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 V_DD

reaches

1 V. After minimum V_DD(≥2 V) is

established, the circuit monitors SENSE voltage and

keeps the reset outputs active as long as SENSE

voltage (V_I(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, t_d, is determined by an external

capacitor:

t_d= 2.1 × 10⁴× C_T

Where

C_Tis in farads

t_dis 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, t_d, 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 the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
