TPD4125AK
The TPD4125AK 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 TPD4125AK.

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 VCC 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 VCC voltage is steady. Both of the order of
the VBB power supply and the VCC power supply are not cared about either.
Note that if the power supply is switched off as described above, this product may be destroyed if
the current regeneration route to the VBB power supply is blocked when the VBB line is
disconnected by a 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 VCC voltage or the VBS voltage drops.
When the VCC power supply falls to this product internal setting VCCUVD (=11 V typ.), all IGBT
outputs shut down regardless of the input. This protection function has hysteresis. When the VCC
power supply reaches 0.5 V higher than the shutdown voltage (VCCUVR (=11.5 V typ.)), this product is
automatically restored and the IGBT is turned on again by the input. DIAG output is reversed at the
time of VCC under-voltage protection. When the VCC power supply is less than 7 V, DIAG output isn't
sometimes reversed. When the VBS supply voltage drops VBSUVD (=9 V typ.), the high-side IGBT
output shuts down. When the VBS supply voltage reaches 0.5 V higher than the shutdown voltage
(VBSUVR (=9.5 V typ.)), the 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 shut down
after delay times (2 μs typ.)) when "L" signal is inputted 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.

The VCC pin voltage when output is off defines the under voltage protection operating voltage.
Also sweeps from 6 V to increase. The VCC pin voltage when output is on defines the under voltage
protection recovery voltage.
