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
DD
established, the circuit monitors SENSE voltage
and keeps the reset outputs active as long as

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.

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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
