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 flexibility in powertrain, body-electronics safety and driver-information systems where reliability is paramount.
The TPS1H100-Q1 also offers 20% higher current-sense accuracy than alternative devices to enable intelligent, real-time diagnosis of its loading conditions for reduced circuit complexity and advanced system features.
Features of the TPS1H100-Q1 include:
Highest-accuracy current sense: 5-mA current-sense accuracy gives designers the ability to add 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 claimed as the first such product 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 handle voltage surging for inductive load recirculation;
AEC Q100-012 Grade A compliance: Guarantees zero failure for lifetime reliability in automotive and industrial environments.
An automotive BCM reference design addresses common design challenges such as load driving, condition diagnostics and fault detection. Designers can use this TI Designs reference design to quickly design door locks; window lifts; seat heaters; heating, ventilation and air conditioning (HVAC); lamps; and light-emitting diodes (LEDs). Support comes in the form of the TPS1H100EVM evaluation module (EVM) that allows users to evaluate the TPS1H100-Q1 for resistive, capacitive and inductive load layout. The EVM is available for $29.
The TPS1H100-Q1 is available in a 14-pin, 5.0 x 6.4 mm thermally enhanced thin shrink small-outline package (HTSSOP), for $0.80 (1000)..
