The TPS389006-Q1 device is an integrated six multichannel window monitor reset IC with two remote sense pins available in a 16-pin 3 mm x 3 mm QFN package.

This highly accurate multichannel voltage supervisor is ideal 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 TPS389006-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, sequence logging during turn ON or turn OFF, and a built-in ADC for voltage readouts to provide redundant error checking. In addition, TPS389006-Q1 offers a sync feature for tagging rails as they come up. Rail tagging works across multiple instances of TPS389006-Q1 devices.
