Dual-channel smart high-side switch for automotive systems
Texas Instruments TPS2HB08-Q1 Dual-Channel Smart High-Side Switch is designed for use in 12V automotive systems. The device integrates robust protection and diagnostic features to ensure output port protection even through harmful events like short circuits in automotive systems. The device guards against faults through a reliable current limit, which, depending on device variant, is adjustable from 6.4A to 70A. The high current limit range enables for usage in loads that need large transient currents, while the low current limit range offers improved protection for loads that do not need high peak current.
The device also offers a high accuracy analog current sense that enables improved load diagnostics. By reporting load current and device temperature to a system MCU, the device allows predictive maintenance and load diagnostics that enhances the system lifetime.
