3 Description
The TPS22993 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 1.0V to 3.6V. The
switch can be controlled by I2C making it ideal for
usage with processors that have limited GPIO
available. The rise time of the TPS22993 device is
internally controlled in order to avoid inrush current.
The TPS22993 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 TPS22993 is available in a space-saving RLW
package (0.4mm pitch) and is characterized for
operation over the free-air temperature range of
–40°C to 85°C.
