## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. |
| 2 | ANODE | input | LED anode; drive with IF(ON) of 10 to 16 mA (absolute maximum IF 25 mA, peak 50 mA) and reverse voltage limited to 5 V. |
| 3 | CATHODE | input | LED cathode; input return, with VF(OFF) recommended between -3.0 V and 0.8 V to hold the output low. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VSS | power_in | Output-side negative supply/ground; VDD-VSS must be 15 V to 30 V recommended, 35 V absolute maximum. |
| 6 | VO1 | output | Gate drive output (NMOS/PMOS stage common node) with peak output current up to 3.0 A (max pulse width 10 µs) and rail-to-rail swing. |
| 7 | VO2 | output | Gate drive output tied to the PMOS stage, with peak output current up to 3.0 A (max pulse width 10 µs). |
| 8 | VDD | power_in | Output-side positive supply; 15 V to 30 V recommended, 35 V absolute maximum VDD-VSS, with UVLO turn-on threshold 12.5 V typ. and turn-off 11 V typ. |
