DETAILED DESCRIPTION

SiP32413, SiP32414, and SiP32416 are dual n-channel

power MOSFETs designed as high side load switch with

slew rate control to prevent in-rush current. Once enable the

device charges the gate of the power MOSFET to 5 V gate

to source voltage while controlling the slew rate of the turn

on time. The mostly constant gate to source voltage keeps

the on resistance low through out the input voltage range.

For SiP32414, when disable the output discharge circuit

turns on to help pull the output voltage to ground more

quickly. For all parts, in disable mode, the reverse blocking

circuit is activated to prevent current from going back to the

input in case the output voltage is higher than the input

voltage. Input voltage is needed for the reverse blocking

APPLICATION INFORMATION

Input Capacitor

While bypass capacitors on the inputs are not required,

all applications. The bypass capacitors should be placed as

physically close as possible to the device’s input to be

effective in minimizing transients on the input. Ceramic

capacitors are recommended over tantalum because of

their ability to withstand input current surges from low

impedance sources such as batteries in portable devices.
