The capacitor is biased by VCC and must be sufficiently derated for it. Note 2: The following formula shows the detection current: IO = VR ÷ R1 (For VR = 0.5 V) Do not exceed a detection current of 3 A when using this product. (Please go from the outside in the over current protection.) Note 3: 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 4: 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 RS pin connecting the current detection resistor is connected to a comparator in the IC and also functions as a sensor pin for detecting over current. As a result, over voltage caused by a surge voltage, for example, may destroy the circuit. Accordingly, be careful of handling the IC or of surge voltage in its application environment. 11 2008-05-13 TPD4125K Description of Protection Function (1) Over-current protection This product incorporates a over-current protection circuit to protect itself against over-current at startup or when a motor is locked. This protection function detects voltage generated in the current detection resistor connected to the RS pin. When this voltage exceeds VR (=0.5 V typ.), the IGBT output, which is on, temporarily shuts down after a dead time , preventing any additional current from flowing to this product. The next all “L” signal releases the shutdown state. (2) 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. (3) 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.
