TheTLC77xxfamilyofmicropowersupplyvoltage

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

20 19

RESIN

SENSE voltage (V

) remains below the

SENSE

I(SENSE)

threshold voltage. An internal timer delays return

of the output to the inactive state to ensure proper

RESET

system reset. The delay time, t , is determined by

9 10 11 12 13

an external capacitor:

t = 2.1 × 10 × C

Where

C is in farads

t 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, t , 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.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
