Texas Instruments  PTPS1HA08AQPWPRQ1

The TPS1HA08-Q1 is a single-channel high-side load switch intended for use with 12-Vautomotive batteries. The device integrates many protection and diagnostic features.

The TPS1HA08-Q1 provides a high accuracy analog current sense that allows for improveddiagnostics of complex loads (such as multiple parallel loads driven by the same switch).

The TPS1HA08-Q1 is available with both a high current limit and also a low current limit.The high current limit option is designed for loads that require a large transient current. The lowcurrent limit option provides improved protection for loads that do not require high peak current.

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

The TPS1HA08-Q1 is available in a small 16-pin HTSSOP package which allows for reducedPCB footprint.
