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 

×

×

 C

T

Where

C

T

 is in farads

t

d

 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

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.

description (continued)

In addition to the power-on-reset and undervoltage-supervisor function, the TLC77xx adds power-down control

support for static RAM. When CONTROL is tied to GND, RESET will act as active high. The voltage monitor

contains additional logic intended for control of static memories with battery backup during power failure. By

driving the chip select (CS) of the memory circuit with the RESET output of the TLC77xx and with the CONTROL

driven by the memory bank select signal (CSH1) of the microprocessor (see Figure 10), the memory circuit is

automatically disabled during a power loss. (In this application the TLC77xx power has to be supplied by the

battery.)

The TLC77xxI is characterized for operation over a temperature range of –40

°

C to 85

°

C; the TLC77xxQ is

characterized for operation over a temperature range of – 40

°

C to 125

for operation over the full Military temperature range of – 55

C to 125
