Texas Instruments (TI) introduced the industry's first smart, high-side power switch with programmable current limit. As automotive systems become more complex, the various loads within the system can each require different profiles during operation.
Using the TPS1H100-Q1, designers can drive various loads with advanced flexibility in powertrain, body-electronics safety and driver-information systems where reliability is paramount.
The TPS1H100-Q1 also offers 20 percent higher current-sense accuracy versus the competition to enable intelligent, real-time diagnosis of its loading conditions. System designers can benefit from the device's simplicity and flexibility to reduce circuit complexity while advancing their systems.
Features:
－ Highest-accuracy current sense: 5-mA current-sense accuracy gives designers the ability to leverage sophisticated load-checking to adjust the driving profile, detect system deterioration, locate problem areas, or judge circuit conditions.
－ Programmable current limit: The TPS1H100-Q1 is the first to provide adjustable current-limit capability to allow flexible control.
－ High-avalanche energy-dissipation capability: A high-voltage avalanche structure eliminates Zener transient voltage suppressors and free-wheel diodes to address voltage surging for inductive load recirculation.
－ Automotive Electronics Council (AEC) Q100-012 Grade A compliance: Guarantees zero failure for lifetime reliability in automotive and industrial environments.
