MAX6343SUT+T from MAXIM INTEGRATED, in a SOT-23-6. 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; operates from +1V to +5.5V, with a 1µF bypass capacitor recommended close to the pin. |
| 2 | GND | power_in | Ground. |
| 3 | PFI | input | Power-fail voltage monitor input; when PFI is below 1.25V, PFO goes low, and it should be connected to GND or VCC when not used. |
| 4 | PFO | output | Power-fail voltage monitor output, independent of the reset output, which goes low when PFI is below 1.25V. |
| 5 | MR | input | Manual-reset input; pull low to force a reset, which stays active while MR is low and for the reset timeout period after MR goes high, and leave unconnected or connect to VCC if unused. |
| 6 | RESET | output | Active-low open-drain reset output on the MAX6343 that stays low for 180ms after VCC rises above the reset threshold or MR goes from low to high, needing a pull-up resistor to a supply up to +5.5V. |
