The TPS388C0x-Q1 device is an integrated multichannel window monitor reset IC with remote sense pin options and integrated window watchdog available in a 16-pin 3mm x 3mm QFN package.

This highly accurate multichannel voltage supervisor is designed for systems that operate on low-voltage supply rails and have marginal supply tolerances. Internal glitch immunity and noise filters further eliminate false resets resulting from erroneous signals. This TPS388C0x-Q1 device does not require any external resistors for setting overvoltage and undervoltage reset thresholds, which further optimizes overall accuracy, cost, 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. The device has a built in window watchdog with independent watchdog enable.

This device has a low typical quiescent current specification of 1500µA (typical). The TPS388C0x-Q1 is designed for automotive applications and is qualified for AEC-Q100 Grade 1 and qualified as a functional safety compliant device with ASIL-B rating.
