Texas Instruments  PTPS2HB50DQPWPRQ1

The TPS2HB35-Q1 device is a dual-channel smart high-side switch intended for use with12-V automotive batteries. The device integrates many protection and diagnostic features.

This device provides a high-accuracy analog current sense that enables improveddiagnostics of complex loads (such as multiple parallel loads driven by the same switch).

The TPS2HB35-Q1 device includes a programmable current limit, which allows for optimizedprotection in a wide variety of load applications.

The device operates with an input voltage down to
3 V. This input voltage allows for continued operation during cold crank.

The TPS2HB35-Q1 device is available in a small 16-pin HTSSOP package for a reduced PCBfootprint.
