High Voltage Monolithic Silicon Power IC
TPD4123AK
The TPD4123AK is a DC brush less motor driver using high
voltage PWM control. It is fabricated by high voltage SOI process.
It is three-shunt resistor circuit for current sensing. It contains
level shift high-side driver, low-side driver, IGBT outputs, FRDs
and protective functions for under voltage protection circuits and
thermal shutdown circuit. It is easy to control a DC brush less
motor by just putting logic inputs from a MPU or motor controller
to the TPD4123AK.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).

Note 1: The required bootstrap capacitance value varies according to the motor drive conditions. The capacitor is
biased by V and must be sufficiently derated for it.

Note 2: When using this product, adjustment is required in accordance with the use environment. When mounting,
place as close to the base of this product leads as possible to improve the ripple and noise elimination.
Note 3: The DIAG pin is open drain. If not using the DIAG pin, connect to the GND.
Handling precautions
（１） Please control the input signal in the state to which the V
voltage is steady. Both of the order of the
CC
V
BB
power supply and the V
power supply are not cared about either.
CC
Note that if the power supply is switched off as described above, this product may be destroyed if the
current regeneration route to the V power supply is blocked when the V line is disconnected by a
BB
BB
relay or similar while the motor is still running.
（２） The excess voltage such as the voltage surge which exceed the maximum rating is added, for example,
may destroy the circuit. Accordingly, be careful of handling this product or of surge voltage in its
application environment.

Description of Protection Function
(1) Under voltage protection
This product incorporates under voltage protection circuits to prevent the IGBT from operating in
unsaturated mode when the V voltage or the V voltage drops.
CC
BS
When the V
power supply falls to this product internal setting V UVD (=11 V typ.), all IGBT outputs
CC
CC
shut down regardless of the input. This protection function has hysteresis. When the V
power supply
CC
reaches 0.5 V higher than the shutdown voltage (V UVR (=11.5 V typ.)), this product is automatically
CC
restored and the IGBT is turned on again by the input. DIAG output is reversed at the time of V
CC
under-voltage protection. When the V
reversed.
power supply is less than 7 V, DIAG output isn't sometimes
CC
When the V supply voltage drops V UVD (=9 V typ.), the high-side IGBT output shuts down.
BS
BS
When the V
supply voltage reaches 0.5 V higher than the shutdown voltage (V UVR (=9.5 V typ.)), the
BS
BS
IGBT is turned on again by the input signal.
(2) Thermal shutdown
This product incorporates a thermal shutdown circuit to protect itself against the abnormal state when its
temperature rises excessively.
When the temperature of this chip rises to the internal setting TSD due to external causes or internal heat
generation, all IGBT outputs shut down regardless of the input. This protection function has hysteresis
ΔTSD (=50°C typ.). When the chip temperature falls to TSD − ΔTSD, the chip is automatically restored and
the IGBT is turned on again by the input.
Because the chip contains just one temperature detection location, when the chip heats up due to the IGBT,
for example, the differences in distance from the detection location in the IGBT (the source of the heat)
cause differences in the time taken for shutdown to occur. Therefore, the temperature of the chip may rise
higher than the thermal shutdown temperature when the circuit started to operate.
(3) SD pin
SD pin is the input signal pin to shut down the internal output IGBT. Output of all IGBT is shuted down after
delay times (2 μs typ.) when "L" signal is inputed to the SD pin from external circuit (MCU etc.). It is
possible to shut down IC when overcurrent and others is detected by external circuit. Shut down state is
released by all of IC input signal "L". At open state of SD pin, shut down function can not operate.
