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.
