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

RESET output becomes active (low) to prevent

undefined operation. If the supply voltage drops

output goes to the active (low) level until the
