MAX6457UKD3A+T from Maxim Integrated, 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 | OUT | output | Open-drain monitor output that requires an external pullup resistor, asserts low for VCC between 1.5V and 4V, goes low when VIN+ drops below VTH- and goes high after the timeout period (tTP) when VIN+ exceeds VTH+. |
| 2 | GND | power_in | Ground. |
| 3 | IN+ | input | Adjustable undervoltage monitor threshold input, operating within 0 to VCC. |
| 4 | CLEAR | input | Clear input: drive high to latch OUT high when VIN+ exceeds VTH+, connect to GND for transparent operation, and it must be low when powering up the device (VIL max 0.4V, VIH min 2V). |
| 5 | VCC | power_in | Supply voltage, operating range 4V to 28V. |
