TPS3106K33DBVR

The TPS3106K33DBVR is an ultralow-supply current/supply-voltage Supervisory Circuit with active-low open-drain output. The supervisory circuit provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, /RESET is asserted low when the supply voltage (VDD) becomes higher than 0.4V. Thereafter, the supervisory circuit monitors VDD and keeps the /RESET output low as long as VDD remains below the threshold voltage (VIT-). To ensure proper system reset, after VDD surpasses the threshold voltage, an internal timer delays the transition of the /RESET signal from low to high for the specified time. When VDD drops below VIT-, the output transitions low again. It has a fixed-sense threshold voltage (VIT-) set by an internal voltage divider.
