DESCRIPTION  
The TLC77xx family of micropower supply voltage  
supervisors provide reset control, primarily in  
microcomputer and microprocessor systems.  
During power-on, RESET is asserted when VDD  
reaches  
1 V. After minimum VDD (≥2 V) is  
established, the circuit monitors SENSE voltage and  
keeps the reset outputs active as long as SENSE  
voltage (VI(SENSE)  
) remains below the threshold  
voltage. An internal timer delays return of the output  
to the inactive state to ensure proper system reset.  
The delay time, td, is determined by an external  
capacitor:  
td = 2.1 × 104 × CT  
Where  
CT is in farads  
td is in seconds  
SPACER  
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, td, has expired.
