The TPS1HB16-Q1 device is a smart high-side switch intended for use in 12-V automotive systems. The device integrates robust protection and diagnostic features to ensure output port protection even during harmful events like short circuits in automotive systems. The device protects against faults through a reliable current limit, which, depending on device variant, is adjustable from 4.4 A to 49 A. The high current limit range allows for usage in loads that require large transient currents, while the low current limit range provides improved protection for loads that do not require high peak current. The device is capable of reliably driving a wide range of load profiles.

The TPS1HB16-Q1 also provides a high accuracy analog current sense that allows for improved load diagnostics. By reporting load current and device temperature to a system MCU, the device enables predictive maintenance and load diagnostics that improves the system lifetime.

The TPS1HB16-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.

參考設計

TIDA-020027 — 車用全功能側視鏡模組參考設計

現代豪華側視鏡包含許多便利功能，除了簡單地提供側視鏡的 X-Y 方向控制以外，還可為駕駛員提供更好更安全的體驗。其中包括可減少眩光的自動調光側視鏡；用於在狹小停車空間內防止側視鏡受損的可摺疊側視鏡模組；用於盲點物體偵測的 LED 指示燈、照地燈和轉向指示燈；以及用於在寒冷條件下為側視鏡除霧和除冰的加熱器。每一項功能的新增都需要更多電子裝置，因此汽車電子設計人員希望能夠設計出隨著負載需求的變化可擴展的多功能整合式解決方案。此參考設計為小尺寸解決方案中考量這類電子裝置的設計提供了出發點。
