DESCRIPTION
The TLV810 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems.
During power-on, RESET is asserted when the supply
voltage (VDD) becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors 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 (low) to ensure proper system reset. The delay time (td(typ) = 200 ms) starts after VDD has risen above the thresh...
