Description

The LS0504EDD12 is a compact, low RON load switch with

controlled slew rate. The device operates over an input voltage

range of 1.8V to 5.5V and can support maximum continuous

current of 4A.

The controlled output slew rate greatly reduces inrush current at

start-up when charging large bulk load capacitances, thereby

minimizes input supply voltage droop. LS0504E comes with builtin

full protections against over current, over voltage and over

temperature. It provides an accurate enable threshold which allows

users to program input under-voltage lockout (UVLO) threshold

through external resistor divider network. It has built-in 8Ω resistor

for quick output discharge at disable.
