The TPS3851H50SQDRBRQ1 from Texas Instruments is an automotive-grade, high-accuracy voltage supervisor featuring an integrated watchdog timer. This device is designed for reliable system monitoring, offering a precise undervoltage threshold accuracy of 0.8% across its operating temperature range of -40°C to 125°C.
Key electrical characteristics include an input voltage range of 1.6V to 6.5V and a low supply current of 10µA typical. It supports common rails from 1.8V to 5.0V with available undervoltage thresholds of 4% and 7%, and includes 0.5% hysteresis for stable operation in tight tolerance systems. The supervisor also features a reset timeout of 170ms minimum and an active-low reset output.
Packaged in a compact 8-SON (3x3) or 8-VDFN exposed pad, the TPS3851H50SQDRBRQ1 is suitable for surface mount applications. Its AEC-Q100 qualification, including specific HBM and CDM ESD classifications, ensures suitability for demanding automotive environments. The device also includes a user-programmable watchdog timeout and a watchdog disable feature.
