IR1161LTRPBF from Infineon Technologies, 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 | VCC | power_in | Supply voltage pin monitored by the UVLO circuit, with a recommended operating range of 4.75 V to 18 V and an internal clamp at 20 V. |
| 2 | GND | power_in | IC ground reference, connected to the SR MOSFET source. |
| 3 | MOT | input | Minimum On Time programming input, set by an external resistor (5 kΩ to 100 kΩ recommended) connected to GND. |
| 4 | VD | input | High-voltage FET drain sense input rated for up to 200 V, with a -3 V negative spike allowed only for widths of 100 ns or less. |
| 5 | GATE | output | Gate drive output with 1 A peak source and 2.5 A peak sink capability, where a minimal gate resistor is recommended. |
