DESCRIPTION
The TPS22967 is a small, ultra-low R_ON, single
channel load switch with controlled turn on. The
device contains an N-channel MOSFET that can
operate over an input voltage range of 0.8V to 5.5V
and can support a maximum continuous current of
4A. The switch is controlled by an on/off input (ON),
which is capable of interfacing directly with low-
voltage control signals. In the TPS22967, a 225-Ω
pull-down resistor is added for quick output discharge
when switch is turned off.
The TPS22967 is available in a small, space-saving
2mm x 2mm 8-pin SON package (DSG) with
integrated thermal pad allowing for high power
dissipation. The device is characterized for operation
over the free-air temperature range of –40°C to 85°C.
