MCP1316MT-30HE from Microchip Tech, 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 | RST | output | Active-low open-drain Reset output with internal pull-up resistor (typically 4.7 kΩ) on the MCP1316M that goes low when VDD falls below VTRIP, MR is forced low, WDI sees no edge within the time-out period, or during power-up. |
| 2 | VSS | power_in | Ground reference for the device. |
| 3 | MR | input | Active-low Manual Reset input with internal pull-up and noise filtering, which allows a push button to ground to force RST active. |
| 4 | WDI | input | Watchdog Timer input where an edge transition resets the watchdog counter, a falling edge is required to start the timer, and no edge within the time-out period forces RST active. |
| 5 | VDD | power_in | Positive supply for the device and the monitored voltage, with operating range of 1.0V to 5.5V. |
