Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS1 | power_in | Ground reference for the primary (logic) side; pin 1 is shorted internally to pin 8 per the package characteristics note. |
| 2 | VI+ | input | Positive logic CMOS drive signal input, referenced to VSS1, with logic-high threshold of 0.7 × VDD1 and logic-low threshold of 0.29 × VDD1 (Table 1). |
| 3 | VI− | input | Negative logic CMOS drive signal input, referenced to VSS1, using the same CMOS thresholds as VI+ (Table 1). |
| 4 | READY | output | Open-drain logic output that needs a pull-up resistor; high indicates the device is functional and ready, and READY low prevents the gate output from going high. |
| 5 | FAULT | output | Open-drain logic output that needs a pull-up resistor; low indicates a desaturation fault, and a fault prevents the gate output from going high. |
| 6 | RESET | input | CMOS input with an internal 300 kΩ (typical) pull-down; bring low for at least the 500 ns debounce time to clear a fault. |
| 7 | VDD1 | power_in | Primary-side logic supply, 2.5 V to 6 V referenced to VSS1. |
| 8 | VSS1 | power_in | Ground reference for the primary side; shorted internally to pin 1. |
| 9 | VSS2 | power_in | Negative secondary-side supply, −15 V to 0 V referenced to GND2; shorted internally to pin 16. |
| 10 | DESAT | bidirectional | Desaturation detection pin, connected to an external current source or pull-up resistor; the comparator threshold is 9.2 V typical (8.73 V to 9.61 V), and a fault here asserts FAULT on the primary side. |
| 11 | GND2 | power_in | Secondary-side ground reference; connect to the emitter of the IGBT or source of the MOSFET being driven. |
| 12 | VOUT_OFF | output | Gate drive output current path for the off signal; absolute maximum voltage is −0.3 V to VDD2 + 0.3 V referenced to VSS2. |
| 13 | VDD2 | power_in | Secondary-side supply, 12.25 V to 30 V referenced to GND2, with VDD2 − VSS2 not to exceed 30 V. |
| 14 | VOUT_ON | output | Gate drive output current path for the on signal; absolute maximum voltage is −0.3 V to VDD2 + 0.3 V referenced to VSS2. |
| 15 | GATE_SENSE | bidirectional | Gate voltage sense input for Miller clamping and Miller clamp output; connect to the gate of the driven device, or tie to VSS2 if the Miller clamp is not used. |
| 16 | VSS2 | power_in | Negative supply for the secondary side, −15 V to 0 V referenced to GND2; shorted internally to pin 9. |
