EUP3504
1.8A Line Switch with Low On-Resistance
DESCRIPTION
The EUP3504 is a low dropout line switch IC with ON/OFF control and output current protection which integrates a P-channel MOSFET.
By connecting the EUP3504 to the output pin of a step-down DC/DC converter, the EN pin controls ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the EUP3504 helps to extend battery life and product operation time.
The EUP3504 contains a current limit protection circuit so these are not required externally unlike discrete circuit solutions where MOSFETs and resistors are used. Externally programmable soft-start allows for proper power on sequencing with respect to other power supplies and avoids input inrush current during startup.
