Processor Supervisor 2.93V 0V to 5.8V 5-Pin SOT-23 T/R

The TPS3825 is supervisors provide circuitinitialization and timing supervision, primarily for DSPand processor-based systems. During power-on,RESET asserts when the supply voltage VDDbecomes higher than 1.1 V. Thereafter, the supplyvoltage supervisor monitors VDD and keeps RESETactive as long as VDD remains below the thresholdvoltage, VIT-. An internal timer delays the return ofthe output to the inactive state (high) to ensure propersystem reset. The delay time, td, starts after VDD hasrisen above the threshold voltage, VIT-. When thesupply voltage drops below the threshold voltageVIT-, the output becomes active (low) again. Noexternal components are required. All the devices ofthis family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider.
