The TPS3307-18MDREPG4 from Texas Instruments is a multi-voltage supervisor that monitors three supply rails simultaneously: a fixed 1.68 V threshold, a fixed 2.93 V threshold, and one adjustable input that you set with an external resistor divider. It asserts a reset signal — available as both active-high and active-low outputs — whenever any monitored voltage falls below its threshold, and holds reset for a minimum of 140 ms after all rails return to tolerance. The push-pull, totem-pole output stage drives the reset line directly without an external pull-up resistor, simplifying the BOM on the processor interface.

Frequently asked questions
What is the reset timeout of TPS3307-18MDREPG4?
The reset timeout is a minimum of 140 ms. After all monitored voltages rise above their thresholds, the reset output remains asserted for at least this duration before releasing the processor.
