ETA6021S2F

etasolution · Power Distribution Switches · SOT23-5

ETA6021S2F from etasolution, in a SOT23-5. 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	Power input with an operating range of 2.5 V to 5.5 V; bypass with a 4.7 µF capacitor to GND as close to the device as possible.
2	GND	power_in	Ground reference pin for the device.
3	EN	input	Enable pin that controls the switch; the datasheet gives an EN logic high threshold of 1 V and a logic low threshold of 0.66 V at VIN = 5.5 V.
4	ILIM	passive	Current limit threshold setting pin; connect a precision resistor from this pin to GND to program the current limit from 75 mA to 1.7 A.
5	OUT	power_out	Current-limited switch output that must not exceed VIN + 0.3 V to GND; bypass with a capacitor greater than 120 µF if used for USB.
