3 Description
The TPS22958x is a small, single channel load
switch with an adjustable rise time. The device
contains an N-Channel MOSFET that can operate
over an input voltage range of 0.6 V to 5.5 V and can
support a maximum continuous current of 4 A (DGK
package) or 6 A (DGN package). The switch is
controlled by an on/off input, which is capable of
interfacing directly with low voltage control signals.
The rise time of the device can be externally
controlled in order to avoid inrush current. Attaching a
capacitor to the CT pin will change the rise time:
increasing the value of the capacitor will increase the
rise time. The TPS22958x is available in two space-
saving packages (DGK and DGN) with or without a
thermal pad for high power dissipation. The device is
characterized for operation over the free-air
temperature range of -40°C to 105°C.
