The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, saving a component on the BOM. ## 140 ms reset timeout — what it buys the processor The minimum reset timeout of 140 ms gives the power supply time to stabilise and the processor time to complete its internal reset sequence before the supervisor releases the reset line. For a typical microcontroller or DSP, that window covers the power-on ramp and the oscillator start-up period without the need for an external delay capacitor. ## Industrial temperature, 8-SOIC footprint","metaTitle":"Texas Instruments TPS3305-33DG4 Multi-Voltage Supervisor","metaDescription":"Texas Instruments TPS3305-33DG4 multi-voltage supervisor monitors two rails at 2.93V and 4.55V.
