It asserts a reset output when either monitored voltage drops below its threshold, and holds reset active for a minimum of 70 ms after both rails recover, giving the downstream processor time to stabilize before release. ## Open-drain output and wired-OR flexibility The output is open-drain, active-low — this lets you wire-OR the reset signal with other supervisors or a manual reset button without adding external logic gates. A pull-up resistor to the I/O rail is required; the value sets the rise time on the reset line.","metaTitle":"TPS3306-25DG4 Multi-Voltage Supervisor","metaDescription":"Texas Instruments TPS3306-25DG4 dual voltage supervisor monitors 2.5V and 3.3V rails with 70ms min reset timeout.
