●Description
BD5413EFV is a 5W + 5W stereo class-D power amplifier specifically developed for low power consumption and low heat
generation applications like powered speakers. BD5413EFV employs the state-of-the-art BCD (Bipolar, CMOS and DMOS)
process technology to eliminate a turn-on resistance in the output power stage and an internal loss due to a wiring
resistance as much as possible, achieving a high performance of 80% (4W + 4W output with a load resistance of 8Ω). In
addition, BD5413EFV employs a compact power package which dissipates heat via the rear to achieve low power
consumption and low heat generation so that the need for connecting an external heat radiator can be eliminated up to a
total output of 12.8W. This product meets the needs for compact, thin sound generation systems and powerful, high-quality
sound reproduction.
●Features
1) Small output noise voltage capable of achieving a high S/N set
Input conversion noise voltage = 2.8μVrms
A bipolar differential is used for input amplifier to eliminate 1/f noise.
2) Support of power supply voltage ranging from 6V to 10.5V
A supply voltage range is supported that matches an AC adaptor or battery cell driven set.
When a set is battery driven, its operating time can be extended by means of a high performance class-D amplifier.
3) Support of low current consumption mode
A circuit current in shut-down mode is 1μA or less.
4) Built-in soft muting function for reducing pop at shut-down ON or OFF
When a signal is present, its smooth envelope waveform is realized owing to this function.
In addition, when no signal is present, pop generation is eliminated.
A transit time can be adjusted easily through the use of an external capacitor.
5) Realization of high efficiency and low heat generation
Efficiency = 80% (4W+4W (Vcc=9V, RL=8Ω) output can be made without using an external heat radiator.)
A compact power package HTSSOP-B24 (7.8mm x 7.6mm) is employed.
6) Built-in function for reducing pop generation at disconnection from the outlet
7) Support of function for sampling frequency selection
An internal PWM sampling frequency can be selected from three frequencies (200kHz, 250kHz and 300kHz).
Countermeasures against interference (beat noise) due to a switching power source can be taken as needed.
8) Realization of high reliability
Countermeasures against short-circuits due to output terminals shorted to VCC or ground can be taken
(support of automatic recovery).
A temperature protection circuit is incorporated (support of automatic recovery).
9) Support of ERROR pin
ERROR output takes place as a warning which indicates an error.
(short-circuits due to output terminals shorted to VCC or ground, or IC high temperature abnormality).

●Absolute maximum ratings
A circuit must be designed and evaluated not to exceed absolute maximum rating in any cases and even momentarily, to
prevent reduction in functional performances and thermal destruction of a semiconductor product and secure useful life and
reliability.

Technical Note

●Notes for use
1. About absolute maximum ratings
If an applied voltage or an operating temperature exceeds an absolute maximum rating, it may cause destruction of a
device. A result of destruction, whether it is short mode or open mode, is not predictable. Therefore, provide a physical
safety measure such as fuse, against a special mode that may violate conditions of absolute maximum ratings.
2. About power supply line
As return of current regenerated by back EMF of output coil happens, take steps such as putting capacitor between
power supply and GND as a electric pathway for the regenerated current. Be sure that there is no problem with each
property such as emptied capacity at lower temperature regarding electrolytic capacitor to decide capacity value. If the
connected power supply does not have sufficient current absorption capacity, regenerative current will cause the voltage
on the power supply line to rise, which combined with the product and its peripheral circuitry may exceed the absolute
maximum ratings. It is recommended to implement a physical safety measure such as the insertion of a voltage clamp
diode between the power supply and GND pins.
3. Potential of GND (1, 7, 8, 13, 18 and 19 pins)
Potential of the GND terminal must be the lowest under any operating conditions.
4. About thermal design
Perform thermal design with sufficient margins, in consideration of maximum power dissipation Pd under actual operating
conditions. This product has an exposed frame on the back of the package, and it is assumed that the frame is used with
measures to improve efficiency of heat dissipation. In addition to front surface of board, provide a heat dissipation pattern
as widely as possible on the back also.
A class-D power amplifier has heat dissipation efficiency far higher than that of conventional analog power amplifier and
generates less heat. However, extra attention must be paid in thermal design so that a power dissipation Pdiss should not
exceed the maximum power dissipation Pd.

5. About operations in strong electric field
Note that the device may malfunction in a strong electric field.
6. Thermal shutdown (TSD) circuit
This product is provided with a built-in thermal shutdown circuit. When the thermal shutdown circuit operates, the output
transistors are placed under open status. The thermal shutdown circuit is primarily intended to shut down the IC avoiding
thermal runaway under abnormal conditions with a chip temperature exceeding Tjmax = 150℃, and is not intended to
protect and secure an electrical appliance. Accordingly, do not use this circuit function to protect a customer's electrical
appliance.
7. About shorting between pins and installation failure
Be careful about direction and displacement of an IC when installing it onto the board. Faulty installation may destroy the
IC when the device is energized. In addition, a foreign matter getting in between IC pins, pins and power supply, and
pins and GND may cause shorting and destruction of the IC.
8. About power-on or power-off sequence
Set the SDX pin (pin 14) to “L” level before initiating the power-on sequence. Similarly, set the SDX pin (pin 14) to “L”
level before initiating the power-off sequence. If such a setting is made, pop reduction is achieved at power-on or power-
off sequence. In addition, note that all power supply pins shall be made active or inactive at the same time.
9. About error output pin (pin 11)
When a high temperature protection function or VCC/GND shorting protection function is activated, an error flag is output
via an error output pin. Because the error output pin is primarily intended to indicate the state of BD5413EFV and is
available only to protect BD5413EFV, it cannot be used for any other purposes.
10.About TEST pin (pin 4)
Do not use the TEST pin. Keep this pin open or connect it to VCC for regular use.
