A programmable current-limit function greatly improves the reliability of the whole system. High-accuracy current sensing allows a better real-time monitoring effect and more-accurate diagnostics without further calibration.

K is a constant value across the temperature and supply voltage.

The CS pin can also report a fault by pulling up the voltage of the Vs active drain and a source voltage clamp is built in to address switching off the energy of inductive loads, such as relays, solenoids, pumps, motors, and so forth. During the inductive switching-off cycle, both the energy of the power supply (EBAT) and the load (ELOAD) are dissipated on the high-side power switch itself. With the benefits of process technology and excellent IC layout, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTPS1H100BQ-Q1\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003edevice can achieve excellent power dissipation capacity. When a fault condition occurs, CS works as a diagnostics report pin. When an open load or short to battery occurs in the on-state, VCS almost equals 0. When the current limit, thermal shutdown\/swing, open load, or short to battery in the off-state occurs, the voltage is pulled up to VCS.\u003c\/p\u003e\n\u003cp\u003eThe project can be used as a high-side power switch for a wide variety of resistive, inductive, and capacitive loads, including low-wattage bulbs, LEDs, relays, solenoids, and heaters.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eCL\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e(Current Limit) resistor can be changed through\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ePR1 Trimmer\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003epotentiometer.
