The TPS389C0XEVM is an evaluation module (EVM) for the TPS389C03-Q1 Multichannel Overvoltage and Undervoltage I2C Programmable Voltage Supervisor and Monitor with Q&A Watchdog.
The TPS389C0XEVM comes with TPS389C0300CRTERQ1 pre-populated on pad U1 or depending on availability TPS389C0XEVM can be fitted with socket J7 to house TPS389C0300CRTERQ1. This IC variant is configured for three integrated multichannel window inputs to monitor three distinct input voltage rails with three remote sense pins. Additionally, this IC variant offers a built in Q&A watchdog and Error Signal monitor with independent watchdog enable and watchdog output. The device also includes internal glitch immunity and noise filters to eliminate false resets resulting from erroneous signals. The TPS389C03-Q1 device does not require any external resistors for setting overvoltage and undervoltage reset thresholds which optimizes and improves the reliability for safety systems.
