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
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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
