detailed description
power switches
n-channel MOSFET
The IN1-OUT n-channel MOSFET power switch has a typical on-resistance of 250 m
at 3.3-V input voltage,
and is configured as a high-side switch.
p-channel MOSFET
The IN2-OUT p-channel MOSFET power switch with typical on-resistance of 1.3
at 3.3-V input voltage and
is configured as a high-side switch. When operating, the p-channel MOSFET quiescent current is reduced to
less than 1.5
A.
charge pump
An internal 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.
driver
The driver controls the gate voltage of the IN1-OUT and IN2-OUT power switches. To limit large current surges
and reduce the associated electromagnetic interference (EMI) produced, the drivers incorporate circuitry that
controls the rise times and fall times of the output voltage.
