The TPS38800-Q1/TPS388R0-Q1 device is a 2 to 8 channel window supervisor IC available in a 16-pin 3mm x 3mm 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.

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. TPS38800-Q1/TPS388R0-Q1 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.
