The APX811/812 are used for microprocessor supervisory circuit
to monitor the power supplies in These circuit 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 240ms after Vcc has risen above the reset threshold.
Reset thresholds suitable for operation with a variety of supply
voltages are available. The APX811/812 have push-pull outputs.
The APX811 has an active low RESET output, while the
APX812 has an active high RESET output.
The APX811/812 devices incorporate a manual reset input, MR .
A low level at MR causes RESET to become active.
The APX811/2 are targeted at 2.5V, 3V, 3.3V and 5V powered
systems and are available with different threshold voltages to
meet the exact needs of the system. They are available in the
space saving SOT143 package and operate over the whole
industrial temperature range, -40 to 85°C.
