LTC4411ES5#TRPBF

Analog Devices · Power Distribution Switches · TSOT-23-5

LTC4411ES5#TRPBF from Analog Devices, in a TSOT-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 Ideal diode anode and positive power supply for the LTC4411, operating over 2.6V to 5.5V; when used as a switch it must be bypassed with a low ESR ceramic capacitor of 1µF (X5R or X7R preferred).
2 GND power_in Power and signal ground for the IC; all voltages are referenced to GND.
3 CTL input Controlled shutdown pin with a weak 3µA pull-down: pull high to shut down the IC, tie to GND to enable it, and it can be left floating when not in use.
4 STAT output Open-drain status indicator that is Hi-Z in forward conduction and pulls down 10µA in reverse turn-off; terminate through a 470k resistor to a high voltage to read conduction, and it may be left floating or grounded when not in use.
5 OUT power_out Ideal diode cathode and output of the LTC4411, to be bypassed with a nominal 1mΩ ESR capacitor of at least 4.7µF; the part is stable with ESRs down to 0.2mΩ.
