The TPS2HCS08-Q1 device is a dual channel, smart high-side switch controlled through a serial peripheral interface (SPI) and is intended for power distribution and actuator drive applications. The device integrates robust protection to ensure output wire and load protection against short circuit or overload conditions. The device features overcurrent protection configurable via SPI with sufficient flexibility to support loads that require large inrush currents and provide improved protection. The device also integrates a programmable fuse profile (current versus time) that turns off the switch under persistent overload condition. The two features together allow optimization of the wire harness for any load profile with full protection.

The device supports a SPI-configurable capacitive charging mode for ECU loads in power distribution switch applications. The device also includes two low power mode (LPM) states, an auto entry mode or a manual entry mode, that enables the device to provide current to the load ECU while only consuming about 10–20µA of current.

The TPS2HCS08-Q1 device also provides a high accuracy digital current sense over SPI that allows for improved load diagnostics. By reporting load current and the channel output voltage and output FET temperature to a system MCU, the device enables diagnosis of switch and load failures.

The TPS2HCS08-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.
