DESCRIPTION
The SM72240 microprocessor supervisory circuit
monitors the power supplies in microprocessor and
digital systems. It provides a reset to the
microprocessor during power-up, power-down,
brown-out conditions, and manual reset.
The SM72240 asserts a reset signal whenever the
supply decreases below the factory-programmed
reset threshold. Reset will be asserted for at least
100ms even after VCC rises above the reset
threshold.
The SM72240 has an active-low open-drain RESET
output.
The SM72240 is suitable for monitoring 5V. With a
low supply current of only 6μA, the SM72240 is ideal
for use in portable equipment. The SM72240 is
available in the 5-pin SOT-23 package.
