BDS2EJAAGUL is an intelligent power switch IC

(IPS) that has two built-in N-channel MOSFETs

capable of carrying 1A current. This switch IC

operates from low input voltages from 0.9V to

3.6V and exhibits a typical on-resistance of 45

mΩ. Built-in safety features include soft-start,

over current protection with fold back current

limiting, under voltage lockout, thermal shut

down and reverse current protection when

power is switched off. BDS2EJAAGUL is

available in a space-saving VCSP50L1 package

and uses an internal N-channel MOSFET for

discharging output capacitance.
