JSMSEMI · Gate Drivers · SOT-23-5
FAN3111ESX-JSM from JSMSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply pin, recommended 5.0 V to 20 V (absolute maximum 25 V), with UVLO thresholds of 4.0 V rising and 3.9 V falling. |
| 2 | GND | power_in | Ground pin, the reference for all voltage ratings. |
| 3 | IN+ | input | Non-inverting logic input (3.3 V compatible, VIH min 2.7 V, VIL max 0.8 V) with an internal 100K resistor to GND, and it can be used as an enable or disable when unused. |
| 4 | IN- | input | Inverting logic input (3.3 V compatible, VIH min 2.7 V, VIL max 0.8 V) with an internal 100K resistor to VDD, and it can be used as an enable or disable when unused. |
| 5 | OUT | output | Gate drive output with 4 A source and 4 A sink peak current, swinging 0 V to VCC. |
