DESCRIPTION
The TLV803 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems.
The TLV803 and TLV863 are functionally equivalent. The TLV863 provides an alternate pinout of the TLV803.
During power-on, RESET asserts when the supply voltage (VDD) becomes greater than 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage VIT....
