The TPS389006/08-Q1 device is an ASIL-D compliant six/eight-channel window supervisor IC with two remote sense pins (six channel version) available in a 16-pin 3mm x 3mm QFN package. The TPS389R06-Q1 device is a six channel window supervisor IC with 2 remote sense pins and a Reset output. 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. I2C 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, 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 offers a sync feature for tagging the rails as the device powers up. The TPS389006 device also pairs with TI’s power-supply sequencer TPS38700 to enable proper power-on sequence in addition to voltage monitoring for SIL-3 level compliance.
