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.
