PM8834TR from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ENABLE_1 | input | Enable input for Driver 1; pull low to disable Driver 1 (OUT1 will be low, PWM1 will be ignored); internally pulled up to VCC with typical 100 kΩ internal resistor; TTL/CMOS-compatible threshold. |
| 2 | PWM_1 | input | PWM input signal for Driver 1 featuring TTL/CMOS-compatible threshold and hysteresis; internally pulled down to GND with 10 μA current generator. |
| 3 | GND | power_in | Ground reference for all internal logic and drivers; connect to PCB ground plane. |
| 4 | PWM_2 | input | PWM input signal for Driver 2 featuring TTL/CMOS-compatible threshold and hysteresis; internally pulled down to GND with 10 μA current generator. |
| 5 | OUT_2 | output | Driver 2 output stage capable of providing up to 4 A drive current to MOSFET or IGBT gates; low ohmic series resistor useful to reduce dissipated power. |
| 6 | VCC | power_in | PM8834 supply voltage; bypass with low ESR MLCC capacitor to GND; operating range 5 V to 18 V. |
| 7 | OUT_1 | output | Driver 1 output stage capable of providing up to 4 A drive current to MOSFET or IGBT gates; low ohmic series resistor useful to reduce dissipated power. |
| 8 | ENABLE_2 | input | Enable input for Driver 2; pull low to disable Driver 2 (OUT2 will be low, PWM2 will be ignored); internally pulled up to VCC with typical 100 kΩ internal resistor; TTL/CMOS-compatible threshold. |
