G697L293T1Uf     SOT-23-5  微处理器复位IC


General Description

The G696/G697 are microprocessor (μP) supervisory

circuits used to monitor the power supplies in μP and

digital systems. They provide excellent circuit reliability

and low cost and adjustments when used with +5V,

+3.3V, +3.0V- powered circuits.

These circuits perform a single function: they assert a

reset signal whenever the VCC supply voltage declines

below a preset threshold, with hysteresis keeping it

asserted for time delay determined by externally programmable

time delay generator after VCC has risen

above the reset threshold. Reset thresholds suitable

for operation with a variety of supply voltages are

available.

The G697L has an open-drain output stage, while the

G696 have push-pull outputs. The G697L’s open-drain

RESET output requires a pull-up resistor that can be

connected to a voltage higher than VCC. The G696L

have an active-low RESET output, while the G696H

has an active-high RESET output. The reset comparator

is designed to ignore fast transients on VCC,

and the outputs are guaranteed to be in the correct

logic state for VCC down to 0.8V.

Low supply current makes the G696/G697 ideal for

use in portable equipment. The G696/G697 are available

in 5-pin SOT23-5 or TSOT-23-5 packages.
