3 Description
The TPS7H2201-SP is a single channel load switch
that provides configurable rise time to minimize inrush
current and reverse current protection. The device
contains a P-channel MOSFET that can operate over
an input voltage range of 1.5 V to 7 V and can
support a maximum continuous current of 6 A. The
switch is controlled by an on and off input (EN), which
is capable of interfacing directly with low-voltage
control signals.
The TPS7H2201-SP is available in a ceramic
package with integrated thermal pad allowing for high
power dissipation. The device is characterized for
operation over the free-air temperature range of
–55°C to 125°C.
