SNVSCC2F November 2022 – July 2024 TPS389C03-Q1
PRODUCTION DATA
The TPS389C03-Q1 family of devices has three
channels that can be configured for over voltage, under voltage or both in a window
configuration. The TPS389C03-Q1 features a highly accurate window threshold voltages
(up to ±5mV) and a variety voltage thresholds
which can be factory configured or set on boot up by I2C commands.
The TPS389C03-Q1 includes the resistors used to set the overvoltage and undervoltage thresholds internal to the device. These internal resistors allow for lower component counts and greatly simplifies the design because no additional margins are needed to account for the accuracy of external resistors.
The TPS389C03-Q1 is designed to assert active low output signals (NIRQ and/or NRST) when the monitored voltage is outside the safe window. The default configuration has the interrupts enabled for over voltage and under voltage faults, sequence timeout set for 1ms, BIST enabled at POR, and over voltage and under voltage debounce set for 102.4µs.
