MAX6457UKD3A+T

Maxim Integrated · Monitors & Reset Circuits · SOT-23-5

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.
