The TPS3805H33DCKR is a dual Voltage Detector with active-low push-pull output. The supervisory circuit provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. The TPS3805 device provides a second adjustable SENSE input. RESET is asserted in case any of the two voltages drops below VIT. During power on, /RESET is asserted when supply voltage VDD becomes higher than 0.8V. Thereafter, the supervisory circuit monitors VDD (or SENSE) and keeps /RESET active as long as VDD or SENSE remains below the threshold voltage VIT. As soon as VDD (SENSE) rises above the threshold voltage VIT, /RESET is de-asserted again.
- ±1.5% High threshold voltage accuracy
