MAX4789EUK+T

Maxim Integrated · Pre-ordered Chips · SOT-23-5

MAX4789EUK+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 IN power_in Input supply, operating from 2.3V to 5.5V; bypass IN with a 0.1µF ceramic capacitor to ground.
2 GND power_in Ground.
3 ON input Active-high switch on input; a logic high (VIH minimum 2.0V) turns the switch on and a logic low (VIL maximum 0.8V) turns it off.
4 FLAG output Open-drain fault output that goes low when the device stays in forward or reverse current limit longer than the blanking time (14ms minimum); it is high impedance when no fault is present or ON is low, and requires an external pullup from FLAG to IN.
5 OUT power_out Current-limited switch output; bypass OUT with a 0.1µF ceramic capacitor to ground.
