General Description
The G690/G691 are microprocessor (P) supervisory
circuits used to monitor the power supplies in P and
digital systems. They provide excellent circuit reliability
and low cost by eliminating external components and
adjustments when used with +5V, +3.3V, +3.0V- pow-
ered circuits.
These circuits perform a single function: they assert a
reset signal whenever the VCC supply voltage declines
below a preset threshold, keeping it asserted for at
least 140ms after VCC has risen above the reset
threshold. Reset thresholds suitable for operation with
a variety of supply voltages are available.
The G691L has an open-drain output stage, while the
G690 have push-pull outputs. The G691L’s open-drain
RESET output requires a pull-up resistor that can be
connected to a voltage higher than VCC. The G690L
have an active-low RESET output, while the G690H
has an active-high RESET output. The reset com-
parator is designed to ignore fast transients on VCC,
and the outputs are guaranteed to be in the correct
logic state for VCC down to 1V.
Low supply current makes the G690/G691 ideal for
use in portable equipment. The G690/G691 are avail-
able in 3-pin SOT89 or SOT23 or SC70 packages.
