TPD4105AK
TOSHIBA Intelligent Power Device
High Voltage Monolithic Silicon Power IC
TPD4105AK
The TPD4105AK is a DC brushless motor driver using
high- voltage PWM control. It is fabricated using a high-voltage
SOI process. The device contains a level shift high side driver,
low side driver, IGBT outputs, FRDs and protective functions for
under-voltage protection circuits, and a 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 TPD4105AK.

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 the DIAG pin is not used, connect to the GND.
Handling precautions
(1)
(2)
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.
The excess voltage such as the voltage surge which exceed the maximum rating is added, for
example,ay 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.
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 excessive rise in
temperature.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 between the detection location and the IGBT (the
source of the heat) can cause differences in the time taken for shutdown to occur. Therefore, the
temperature of the chip may rise higher than the initial thermal shutdown temperature.

*:Note:Sweeps the VCC pin voltage from 15 V to decrease and monitors the U pin voltage.
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.
