supervisors provide reset control, primarily in  
microcomputer and microprocessor systems.  
During power-on, RESET is asserted when V

reaches 1 V. After minimum V  
(≥ 2 V) is

established, the circuit monitors SENSE voltage  
and keeps the reset outputs active as long as

Except for the TLC7701, which can be customized with two external resistors, each supervisor has a fixed  
SENSE threshold voltage set by an internal voltage divider. When SENSE voltage drops below the threshold  
voltage, the outputs become active and stay in that state until SENSE voltage returns above threshold voltage  
and the delay time, t , has expired.
