TEXAS Instruments (TI) has released the industry’s first smart, high-side power switch with programmable current limit.
The smart power switch replaces discrete components in powertrain and automotive body electronics, providing the highest current sense and accurate diagnostics without calibration.
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 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.
Key features and benefits of the TPS1H100-Q1:
- 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.
