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.
