Single-channel load switch with an integrated N-channel MOSFET, in a SOT-23-6 package. It connects VIN to VOUT under an active-high ON control, from a 1 to 5.5 V rail at up to 2 A, with a low on-resistance. An external capacitor on CT sets the output slew rate to tame inrush, and QOD gives a controlled quick output discharge when the switch turns off. The clean way to sequence and hot-swap power rails to sub-circuits.

Pinout

Pin	Name	Type	Function
1	VIN	power_in	Switch input, 1 V to 5.5 V. Place ceramic bypass capacitor(s) (>=1 uF recommended) between this pin and GND. Absolute max 6 V.
2	GND	power_in	Device ground reference.
3	ON	input	Active-high switch control input. VIH >= 1 V, VIL <= 0.5 V (VIN = 1 to 5.5 V). Low-voltage compatible (1 V or higher GPIO). Do not leave floating.
4	CT	passive	Switch slew-rate (rise-time) control. Connect an external capacitor to GND to program the rise time; may be left floating for the default rise time.
5	QOD	passive	Quick Output Discharge pin. Configure by placing an external resistor between VOUT and QOD, tying QOD directly to VOUT to use the internal pull-down (RPD ~24-45 Ohm depending on VIN), or leaving floating to disable QOD.
6	VOUT	power_out	Switch output. Connected to VIN through the internal N-channel MOSFET (RON ~52 mOhm typ at VIN = 5 V; 53 mOhm typ at VIN = 3.3 V). Supports up to 2 A continuous.
