Description
The SC33001A/AH are a family of an ultra-low Rdson load
switch optimized for use in battery powered applications.
This family of devices support up to 3A continuous output
current. Sophisticated integrated circuitry maximizes
Vgs of the power NMOS to minimize Rdson resistance
over a wide range of operating conditions.
The device provides a controlled soft-start to limit inrush
current. SC33001A features an automatic discharge
circuit which discharges the output when the SC33001A is
disabled. SC33001AH does not include the automatic
output discharge circuitry.
SC33001A/AH family has integrated current limit and over
temperature to prevent the device from failure when
down stream circuitry is at low impedance fault
conditions.
The SC33001A/AH are oered in an ultra small 6-bump
0.9mm x 1.4mm Chip Scale Package (CSP) which enables
very small board area implementations. The SC33001A/
SC33001AH has an operating temperature range of -40

to +85
