It asserts a reset signal — available in both active-high and active-low polarities — when either monitored voltage drops below its threshold, and holds reset for a minimum of 140ms after both rails recover. ## Thresholds and reset timing for processor sequencing The 2.93V threshold monitors a nominal 3.3V rail, while the 2.25V threshold monitors a 2.5V rail — together they cover the core and I/O supplies common on mixed-voltage boards with FPGAs, DSPs, or dual-supply MCUs. The 140ms minimum reset timeout gives the downstream processor time to stabilize its internal oscillators and PLLs before the reset de-asserts. Both push-pull outputs source and sink current directly, so no external pull-up resistor is needed on the active-low output, and the active-high output drives a logic high without a pull-up. The totem-pole stage handles capacitive loads on the reset line without extra buffering.","metaTitle":"TPS3305-25DR Multi-Voltage Supervisor, 2.25V/2.93V Threshold","metaDescription":"Texas Instruments TPS3305-25DR dual-voltage supervisor monitors 2.25V and 2.93V thresholds.
