The TPS2H160-Q1 family is a fully-protected dual-channel smart high-side switch, with integrated 160-mΩ NMOS power FETs. Full diagnostics and high-accuracy current-sense features enable intelligent control of the load. An external adjustable current limit improves reliability of the whole system by limiting the inrush or overload current.

The TPS2HB16-Q1 device is a dual-channel smart high-side switch intended for use in 12-V automotive systems. The device integrates robust protection and diagnostic features to ensure output port protection even during harmful events like short circuits in automotive systems. The device protects against faults through areliable current limit, which, depending on device variant, is adjustable from 4.1 A to 48.5 A. The TPS2HB16F-Q1 device is designed to be able to drive 2x35W, 2x27W, and 2x21W bulbs due to its high fixed current limit of 60A. The high current limit range allows for usage in loads that require large transient currents, while the low current limit range provides improved protection for loads that do not require high peak current. The device is capable of reliably driving variousload profiles. The TPS2HB16-Q1 also provides a high accuracy analog current sense that allows for improved load diagnostics. By reporting load current and device temperature to a system MCU, the device enables predictive maintenance and load diagnostics that improves the system lifetime. The TPS2HB16-Q1 is available in a HTSSOP package which allows for reduced PCB footprint. The TPS2HB16-Q1 device is a dual-channel smart high-side switch intended for use in 12-V automotive systems.

The TPS310x and TPS311x families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on,RESETis asserted when the supply voltage (VDD) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors VDDand keeps theRESEToutput active as long as VDDremains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive state to ensure proper system reset. The delay time starts after VDDhas risen above VIT. When VDDdrops below VIT, the output becomes active again. All the devices of this family have a fixed-sense threshold voltage (VIT) set by an internal voltage divider. The TPS3103 and TPS3106 have an active-low, open-drainRESEToutput. The TPS3110 has an active-low push/pullRESET. The product spectrum is designed for supply voltages of 0.9 V up to 3.3 V. The circuits are available in SOT23-6 packages. The TPS31xx family is characterized for operation over a temperature range of -55°C to 125°C.
