The TPS2HCS10-Q1 device is a dual channel, smart high-side switch controlled through a serial peripheral interface (SPI). The device integrates robust protection to ensure output wire and load protection against short circuit or overload conditions. The device features overcurrent protection which is configurable via SPI in two ranges of thresholds. This allows sufficient flexibility to support loads that require large inrush currents, while providing improved protection. Further, the device integrates a programmable fuse profile (current versus time) that turns off the switch under persistent overload condition, thereby reducing the overhead on the MCU. These 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 a low quiescent current ON-state that provides up to 800 mA of peak current while consuming about 10 µA of current.

The TPS2HCS10-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 TPS2HCS10-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.
