EUP3506
Dual 1.5A Line Switch with Low On-ResistanceDescription
The EUP3506 contains two independent low dropout line switches with ON/OFF control, output current soft-start and output current protection.
By connecting the EUP3506 to the output pins of two step-down DC/DC converters, the EN1/EN2 pins control ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the EUP3506 helps to same system power and extend battery life.
When a low signal is inputted to the EN pin, each switch enters shutdown mode. Even a load capacitor is connected to the output pin during shutdown, the electric charge stored at the load capacitor is discharged through the internal switch. As a result, the VOUT pin voltage falls quickly to the GND level. Externally programmable soft-start allows proper power on sequencing with respect to other power supplies and avoids input inrush current during startup.
Other features include current limit protection and thermal shutdown protection.
