detailed description
power switch
The power switch is an N-channel MOSFET with a maximum on-state resistance of 95 m
(VI(IN) = 5.5 V),
configured as a high-side switch.
charge pump
An internal 100-kHz charge pump supplies power to the driver circuit and provides the necessary voltage to pull
the gate of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7 V and
requires very little supply current.
