The SM72240MFE-3.08/NOPB 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 SM72240MFE-3.08/NOPB 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 SM72240MFE-3.08/NOPB has an active-low open-drain RESET output.
The SM72240MFE-3.08/NOPB is suitable for monitoring 5V. With a low supply current of only 6μA, the SM72240MFE-3.08/NOPB is ideal for use in portable equipment. The SM72240MFE-3.08/NOPB is available in the 5-pin SOT-23 package.
