The TPS2HCS05-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 establish output wire and load protection against short-circuit or overload conditions. The device features overcurrent protection configurable through 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 conditions. Together, the two features allow for the optimization of the wire harness for any load profile with full protection.
The device supports an 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 and a manual entry mode, that enables the device to provide current to the load ECU while only consuming from 10µA to 32µA of current.
The TPS2HCS05-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 the diagnosis of switch and load failures.
The TPS2HCS05-Q1 is available in a HTSSOP package which allows for a reduced PCB footprint.
