TPS389C0xEVM Multichannel Voltage Supervisor with
Watchdog and I
Description
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.
