EUP3506
Dual 1.5A Line Switch with
Low On-Resistance
DESCRIPTION
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.
