Product Summary

The TPS3823-25QDBVRQ1 is a supervisor provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET is asserted when supply voltage VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitor VDD and keeps RESET active as long as VDD remains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage VIT. When the supply voltage of the TPS3823-25QDBVRQ1 drops below the threshold voltage VIT-, the output becomes active (low)again. No external components are required. The TPS3823-25QDBVRQ1 has a fixed-sense threshold voltage VIT- set by an internal voltage divider.
