Texas Instruments PTPS2HB08FQPWPRQ1
The TPS2HB08-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.
The 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 TPS2HB08-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 (as measured with respect to the device GND pin). This input voltage allowsfor continued operation when the battery voltage drops during cold crank.
The TPS2HB08-Q1 device is available in a small 24-pin HTSSOP package for a reduced PCBfootprint.
