The TPS22994 is a multi-channel, low RON load switch with user
programmable features. The device contains four N-channel MOSFETs that can operate over an input
voltage range of 1.0 V to 3.6 V. The switch can be controlled by I2C
making it ideal for usage with processors that have limited GPIO available. The rise time of the
TPS22994 device is internally controlled in order to avoid inrush current. The TPS22994 has five
programmable slew rate options, four ON-delay options, and four quick output discharge (QOD)
The channels of the device can be controlled via either GPIO or
I2C. The default mode of operation is GPIO control through the ONx
terminals. The I2C slave address terminals can be tied high or low to
assign seven unique device addresses.
The TPS22994 is available in a space-saving RUK package (0.4-mm pitch) and is
characterized for operation over the free-air temperature range of –40°C to 85°C.
