Stresses beyond those listed under "Absolute Maximum Ratings" may cause p'ermanent damage to the device. These are stress rat- ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of  the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The G692/G693 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. The G692/G693 also provide a de-
bounced manual reset input.

These circuits of G692/G693 perform a single function: they assert a  reset signal whenever the V_CC supply voltage declines  below a preset threshold, keeping it asserted for at
least 140ms after V_CC has risen above the reset  threshold. Reset thresholds suitable for operation with  a variety of supply voltages are available.

The G693L has an open-drain output stage, while the  G692 have push-pull outputs. The G693L's open-drain  RESET   output requires a pull-up resistor that can be  connected to a voltage higher than V_CC. The G692L  have an active-low  RESET   output, while the G692H  has an active-high RESET output. The reset com- parator is designed to ignore fast transients on V_CC,  and the outputs are guaranteed to be in the correct  logic state for V_CC down to 1V.

Low supply current makes the G692/G693 ideal for  use in portable equipment. The G692/G693 are avail-able in a 4-pin SOT143 packages.
