Texas Instruments TPS1HB08-Q1 Smart High-Side Switch is designed for usage in 12V automotive systems. The device combines robust protection and diagnostic features to secure output port protection, even through harmful events such as short circuits in automotive systems. The device protects against faults within a reliable current limit, which, depending on device version, is adaptable from 6.4A to 70A or set at 94A. The high current limit range provides for usage in loads that demand large transient currents, while the low current limit range provides improved protection for loads that do not need high peak currents. The device can reliably drive a broad range of load profiles.
The device also offers a high accuracy analog current sense that provides for improved load diagnostics. By reporting load current and device temperature to a system MCU, the device facilitates predictive maintenance and load diagnostics that enhance the system lifetime. The device is offered in an HTSSOP package, which provides for a smaller PCB footprint.
Typical applications include automotive display modules, 65W automotive headlights, ADAS modules, seat comfort modules, transmission control units, HVAC control modules, body control modules, and incandescent and LED lighting.
