Compact ultra-low RON dual-channel load switch with controlled turn on

10-02-2015 | Texas Instruments | Power

The TPS22968 is a compact new ultra-low RON dual-channel load switch with
controlled turn on from Texas Instruments (TI).

The TPS22968 is available in a small, space-saving package (DPU) with
integrated thermal pad allowing for high power dissipation. The device is
characterized for operation over the free-air temperature range of -40C to
85C.

The device contains two N-channel MOSFETs that can operate over an input
voltage range of 0.8V to 5.5V and can support a maximum continuous current
of 4A per channel. Each switch is independently controlled by an on/off
input (ON1 and ON2), which is capable of interfacing directly with
low-voltage control signals. In TPS22968, a 270ohm on-chip load resistor is
added for output quick discharge when switch is turned off.
