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 VDD (≥ 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:

td = 2.1 × 104 × C

T

Where

CT 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, 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.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

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°C; and the TLC77xxM is characterized
for operation over the full Military temperature range of –55°C to 125°C.
