Multiple voltage regulator with
switch and ignition buffers
TDA3618JR
FUNCTIONAL DESCRIPTION
The hold output is enabled (LOW) at low battery voltages.
This indicates that it is not possible to get regulator 1 into
regulation when switching it on. The hold function includes
hysteresis to avoid oscillations when the regulator voltage
crosses the hold threshold. Pin HOLD also becomes LOW
when the switch is in foldback protection mode; see Fig.4
for a timing diagram. The hold circuit block diagram is
given in Fig.3.
The TDA3618JR is a multiple output voltage regulator with
a power switch, intended for use in car radios with or
without a microcontroller. Because of the low-voltage
operation of the car radio, low-voltage drop regulators are
used in the TDA3618JR.
Regulator 2 switches on when the backup voltage
exceeds 6.5 V for the first time and switches off again
when the output voltage of regulator 2 falls below 1.9 V
(this is far below an engine start). When regulator 2 is
switched on and its output voltage is within its voltage
range, the reset output is enabled to generate a reset to
the microcontroller. The reset cycle can be extended by an
external capacitor at pin CRES. The start-up feature is
built-in to secure a smooth start-up of the microcontroller
at first connection, without uncontrolled switching of
regulator 2 during the start-up sequence.
The power switch can also be controlled by means of a
separate enable input (pin ENSW).
All output pins are fully protected. The regulators are
protected against load dump (regulators 1 and 3 switch off
at supply voltages >18 V) and short-circuit (foldback
current protection).
The switch contains a current protection. However, this
protection is delayed at short-circuit by the reset delay
capacitor. During this time, the output current is limited to
a peak value of at least 3 A and continuous current of 2 A
(VP ≤ 18 V).
The charge of the backup capacitor can be used to supply
regulator 2 for a short period when the supply drops to 0 V
(the time depends on the value of the storage capacitor).
In the normal situation, the voltage on the reset delay
capacitor is approximately 3.5 V (depending on
temperature). The switch output is approximately
VP − 0.4 V. At operational temperature, the switch can
deliver at least 3 A. At high temperature, the switch can
deliver approximately 2 A. During an overload condition or
short-circuit (VSW < VP − 3.7 V), the voltage on the reset
delay capacitor rises 0.6 V above the voltage of
The output stages of regulators 1 and 3 have an extremely
low noise behaviour and good stability. These regulators
are stabilized by using small output capacitors.
When both regulator 2 and the supply voltage (VP > 4.5 V)
are available, regulators 1 and 3 can be operated by
means of enable inputs (pins EN1 and EN3 respectively).
Pin HOLD is normally HIGH and is active LOW. Pin HOLD
is connected to an open-collector NPN transistor and must
have an external pull-up resistor to operate. The hold
output is controlled by a low voltage detection circuit
which, when activated, pulls the warning output LOW
(enabled). The detection outputs of the regulators are
connected to an OR gate inside the IC such that the hold
output is activated (goes LOW) when the regulator
voltages of regulator 1 and/or regulator 3 are out of
regulation for any reason. Each regulator enable input
controls its own detection circuit, such that if a regulator is
disabled or switched off, the detection circuit for that
regulator is disabled.
regulator 2. This rise time depends on the capacitor
connected to pin CRES. During this time, the switch can
deliver more than 3 A. The charge current of the reset
delay capacitor is typically 4 µA and the voltage swing
approximately 1.5 V. When regulator 2 is out of regulation
and generates a reset, the switch can only deliver 2 A and
will go into the foldback protection without delay. At supply
voltages >17 V, the switch is clamped at 16 V maximum
(to avoid externally connected circuits being damaged by
an overvoltage) and the switch will switch off at load dump.
Interfacing with the microcontroller (simple full or semi
on/off logic applications) can be realized with two
independent ignition Schmitt triggers and ignition output
buffers (one open-collector and one push-pull output).
Ignition 1 output is inverted.
The hold circuit is also controlled by the temperature and
load dump protection. Activating the temperature or load
dump protection causes a hold (LOW) during the time the
protection is activated. When all regulators are switched
off, pin HOLD is controlled by the battery line (pin VP),
temperature protection and load dump protection.
The timing diagrams are shown in Figs 4 and 5.

11. The drop-out voltage of the power switch is measured between pins VP and SW.
12. The maximum output current of the power switch is limited to 1.8 A when the supply voltage exceeds 18 V.
A test-mode is built-in. The delay time of the power switch is disabled when a voltage of VP + 1 V is applied to the
switch-enable input.
13. At short-circuit, Isc of the power switch is held constant to a lower value than the continuous current after a delay of
at least 10 ms. A test-mode is built-in. The delay time of the switch is disabled when a voltage of VP + 1 V is applied
to the switch-enable input.

Application information
NOISE
The two examples show how an output capacitor value is
selected.
Table 1 Noise figures
Example 1
NOISE FIGURE (µV)(1)
REGULATOR
Regulators 1 and 3 are stabilized with an electrolytic
output capacitor of 220 µF (ESR = 0.15 Ω).
At Tamb = −30 °C the capacitor value is decreased to
73 µF and the ESR is increased to 1.1 Ω. The regulator will
remain stable at Tamb = −30 °C (see Fig.9).

Example 2
Note
1. Measured at a bandwidth of 200 kHz.
Regulator 2 is stabilized with a 10 µF electrolytic capacitor
(ESR = 3 Ω). At Tamb = −30 °C the capacitor value is
decreased to 3 µF and the ESR is increased to 23.1 Ω.
The regulator will be unstable at Tamb = −30 °C (see
Fig.10).
The noise on the supply line depends on the value of the
supply capacitor and is caused by a current noise (output
noise of the regulators is translated into a current noise by
means of the output capacitors). When a high frequency
capacitor of 220 nF in parallel with an electrolytic capacitor
of 100 µF is connected directly to pins 1 and 14 (supply
and ground), the noise is minimal.
Solution
To avoid problems with stability at low temperatures, the
use of tantalum capacitors is recommended. Use a
tantalum capacitor of 10 µF or a larger electrolytic
capacitor.
STABILITY
The regulators are stabilized with the externally connected
output capacitors. The output capacitors can be selected
using the graphs of Figs 9 and 10. When an electrolytic
capacitor is used, the temperature behaviour of this output
capacitor can cause oscillations at a low temperature.

SOLDERING
The total contact time of successive solder waves must not
exceed 5 seconds.
Introduction to soldering through-hole mount
packages
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg(max)). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
This text gives a brief insight to wave, dip and manual
soldering. A more in-depth account of soldering ICs can be
found in our “Data Handbook IC26; Integrated Circuit
Packages” (document order number 9398 652 90011).
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300 °C it may remain in contact for up to
10 seconds. If the bit temperature is between
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints for more than 5 seconds.
300 and 400 °C, contact may be up to 5 seconds.
