The TPS3703A7280DSERQ1 is a Texas Instruments simple reset/power-on reset IC that monitors a single voltage rail and asserts a reset when the supply drops below 2.8V. The active-low, open-drain output pulls low during undervoltage and releases when the rail recovers — no external pull-up is integrated, so budget a resistor to the supervisor's supply or the monitored rail.
Yes, it is part of the Automotive, AEC-Q100 series, validated for automotive-grade reliability including extended temperature range and stress testing.
The reset output is active-low with an open-drain or open-collector stage. An external pull-up resistor to the supervisor's supply or the monitored rail is required.
