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) resistance options.

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.
