General Description
The G670/G671 are microprocessor (µP) supervisory
circuits used to monitor the power supplies in µP 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. Reset thresholds suitable for
operation with a variety of supply voltages are avail-
able.
The G671L has an open-drain output stage, while the
G670 have push-pull outputs. The G671L’s open-drain
RESET output requires a pull-up resistor that can be
connected to a voltage higher than VCC. The G670L
have an active-low RESET output, while the G670H
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 G670/G671 ideal for
use in portable equipment. The G670/G671 are avail-
able in 3-pin SOT-23, TO-92 and SOT-89 packages.
