description/ordering information
The TL7757 is a supply-voltage supervisor
designed
for
use
in
microcomputer
and
microprocessor
systems.
The
supervisor
monitors the supply voltage for undervoltage
conditions. During power up, when the supply
voltage, VCC, attains a value approaching 1 V, the
RESET output becomes active (low) to prevent
undefined operation. If the supply voltage drops
below threshold voltage level (VIT), the RESET
output goes to the active (low) level until the
supply undervoltage fault condition is eliminated.
