TPS389C03-Q1 I2C Programmable Voltage Supervisors

Texas Instruments TPS389C03-Q1 I²C Programmable Voltage Supervisors are integrated multi-channel window monitor reset ICs with three remote sense pins. These highly accurate multi-channel voltage supervisors are designed for systems operating on low-voltage supply rails and with narrow-margin supply tolerances. Noise filters and internal glitch immunity further eliminate false resets resulting from erroneous signals. The TPS389C03-Q1 does not require any external resistors for setting the overvoltage and undervoltage reset thresholds, which further optimizes overall accuracy, cost, and solution size and improves reliability for safety systems. I²C functionality gives flexibility in selecting thresholds, glitch filters, reset delays, and pin functionality. These devices offer CRC error checking and a built-in ADC for voltage readouts to provide redundant error checking. The devices contain a built-in Q&A watchdog and error signal monitor with an independent watchdog output and watchdog enable. The Texas Instruments TPS389C03-Q1 supervisors are available in a 16-pin 3mm x 3mm QFN package.
