MCP1319T-29LE 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 | Push-pull active-low Reset output that is driven low when VDD falls below the trip point VTRIP, when MR is forced low, and during power-up, and returns high once VDD rises above VTRIP + VHYS and the Reset delay expires. |
| 2 | VSS | power_in | The ground reference for the device. |
| 3 | RST | output | Push-pull active-high Reset output that is driven high when VDD falls below VTRIP, when MR is forced low, and during power-up, and is driven low once VDD rises above VTRIP + VHYS and the Reset delay expires. |
| 4 | MR | input | Active-low Manual Reset input with an internal pull-up resistor that forces both RST/RST outputs active when pulled low by a push-button, and filters noise pulses on the pin. |
| 5 | VDD | power_in | The positive supply for the device, rated for a voltage range of 1.0V to 5.5V. |
