The TPS389006-Q1 device is an ASIL-D compliant six-channel window supervisor IC with two remote sense pins available in a 16-pin 3 mm x 3 mm QFN package. This high accuracy multichannel voltage supervisor is designed for systems that operate on low-voltage supply rails and have narrow margin supply tolerances.

Remote sense pins enable a highly accurate voltage measurement on the high current core rail by accounting for voltage drop across PCB traces. I 2C functionality gives flexibility in selecting thresholds, reset delays, glitch filters, and pin functionality. The internal glitch immunity and noise filters eliminate the need for external RC components to reduce false resets resulting from power transients. In addition, 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.

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. TPS389006-Q1 device also pairs with TI’s power-supply sequencer TPS38700-Q1 to ensure proper power-on sequence in addition to voltage monitoring for ASIL-D level compliance.
