description
The TL7757 is a supply-voltage supervisor
designed for use in microcomputer and
microprocessor
systems.
monitors the supply voltage for undervoltage
conditions. During power up, when the supply
voltage, V
CC
, 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 (V
IT–
), the RESET
output goes to the active (low) level until the
supply undervoltage fault condition is eliminated.
