The TPS389C03-Q1 device is an integrated multichannel window monitor reset IC with three remote sense pins available in a 16-pin 3mm × 3mm QFN package.

This highly accurate multichannel voltage supervisor is designed for systems that operate on low-voltage supply rails and have narrow margin supply tolerances. Internal glitch immunity and noise filters further eliminate false resets resulting from erroneous signals. This TPS389C03-Q1 device does not require any external resistors for setting overvoltage and undervoltage reset thresholds, which further optimizes overall accuracy, cost, solution size, and improves reliability for safety systems. I2C functionality gives flexibility in selecting thresholds, reset delays, glitch filters, and pin functionality. This device offers CRC error checking and a built-in ADC for voltage readouts to provide redundant error checking. The device has a built in Q&A watchdog and Error Signal monitor with independent watchdog enable and watchdog output.
