POWER MANAGEMENT SWITCH
MB3802
I
DESCRIPTION
The MB3802 is a power management switch incorporating two switch circuits with extremely low ON resistance.
NO diode is required because the switch block is configured with an N-ch MOS to prevent reverse current at
swich OFF.
The MB3802 starts at a very low voltage (typical V
of the switching voltage because the intermal DC/DC converter applies the optimum voltage for the N-ch MOS
gate at swith ON.
IN
> 2.2V) and a stable ON resistance is obtained irrespective
Moreover, the load-side capacitor is discharged at switch OFF, and the power supply for various power supply
systems is switched efficiently.
