1 VI+ Positive Logic CMOS Input Drive Signal. 2 VI− Negative Logic CMOS Input Drive Signal. 3 VDD1 Input Supply Voltage on Primary Side, 2.5 V to 6 V. The supply that is connected to this pin must be referenced to VSS1. 4 VSS1 Ground Reference for Primary Side. 5 RESET CMOS Input. When a fault exists, bring this pin low to clear the fault. RESET has an internal 300 kΩ pull-down resistor. 6 FAULT Open-Drain Logic Output. Connect this pin to a pull-up resistor to read the signal. A low state on this pin indicates when a desaturation fault has occurred. The presence of a fault condition precludes the gate drive output from going high. 7 READY Open-Drain Logic Output. Connect this pin to a pull-up resistor to read the signal. A high state on this pin indicates that the device is functional and ready to operate as a gate driver. If READY is low, the gate drive output is precluded from going high. 8 VSS1 Ground Reference for Primary Side. 9 VSS2 Negative Supply for Secondary Side, −15 V to 0 V. The supply that is connected to this pin must be referenced to GND2. 10 VSS2 Negative Supply for Secondary Side, −15 V to 0 V. The supply that is connected to this pin must be referenced to GND2. 11 VOUT Gate Drive Output Current Path for the Device. 12 VDD2 Secondary Side Input Supply Voltage, 12 V to 35 V. The supply that is connected to this pin must be referenced to GND2. 13 VDD2 Secondary Side Input Supply Voltage, 12 V to 35 V. The supply that is connected to this pin must be referenced to GND2. 14 DESAT Detection of Desaturation Condition. Connect this pin to an external current source or a pull-up resistor. A fault on this pin asserts a fault on the FAULT pin on the primary side. Until the fault is cleared on the primary side, the gate drive is suspended. During a fault condition, a smaller turn-off FET slowly brings the gate voltage down. 15 VSS2 Negative Supply for Secondary Side, −15 V to 0 V. The supply that is connected to this pin must be referenced to GND2. 16 GND2 Ground Reference for Secondary Side. Connect this pin to the emitter of the IGBT or the source of the MOSFET being driven.
