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) 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
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 TSD (= 50 C typ.). When the chip temperature falls to TSD - TSD, 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. (1)
