10.1 Application Information

The TPS1210x-Q1 family is a 45-V, low IQ, smart high side driver with protection and diagnostics. The TPS1210x-Q1 device architecture is design to drive and control back-to-back N-Channel MOSFETs independently in common source configuration with separate control inputs (INP1, INP2), which makes TPS1210x-Q1 an excellent choice to realize circuit breaker in battery management system (BMS). The strong (2-A) GATE drivers enable switching parallel MOSFETs in high current applications such as circuit breaker in powertrain (DC/DC converter), driving loads in power distribution unit, circuit breaker in 12-V BMS, and so forth.

The TPS1210x-Q1 device provides configurable short-circuit protection using ISCP and TMR pins for adjusting the threshold and response time respectively. Auto-retry and latch-off fault behavior can be configured. By using CS+ and CS– pins, current sensing can be done either by an external sense resistor or by MOSFET VDS sensing. High side or low side current sense resistor configuration is possible by using CS_SEL pin input. The device also features diagnosis of the internal short circuit comparator using external control on SCP_TEST input.

The following design procedure can be used to select the supporting component values based on the application requirement.
