ZHCSHN4D February 2018 – September 2021 TPS1H200A-Q1
PRODUCTION DATA
The TPS1H200A-Q1 device is a smart high-side switch with an internal charge pump and single-channel integrated NMOS power FET. The adjustable current limit function improves the reliability of the whole system. Full diagnostic features enable intelligent control of the load.
The external high-accuracy current limit sets the current limit value for the application. When overcurrent occurs, the device improves system reliability by clamping the inrush current effectively. The device saves system cost by reducing the size of PCB traces and connectors, and the capacity of the preceding power stage. The TPS1H200A-Q1 device allows three modes when a current limit occurs. Users can set the output to consistently hold the current, to immediately latch off, or to automatically retry through the configuration on the DELAY pin. The configurable behaviors during a current limit provide design flexibility. This includes functionality, cost, and thermal dissipation.
This device supports full diagnostics with the digital status output. High-accuracy and low-threshold open-load detection enables real-time ON state monitoring. The device supports operation without an MCU (stand-alone mode) which allows the system to locally implement full functionality.
The TPS1H200A-Q1 device is a smart high-side switch for a wide variety of resistive, inductive, and capacitive loads, including LEDs, bulbs, relays, solenoids, and submodules.
