Product Summary

The MAX6467US44D3+T is a microprocessor supervisory reset circuit with edge-triggered, one-shot manual reset. The MAX6467US44D3+T microprocessor (μP) supervisory circuit monitors single power-supply voltages from +1.8V to +5.0V and assert a reset if the supply voltage drops below its preset threshold. An edge-triggered, one-shot manual reset function ensures that the μP enters the reset mode for a fixed timeout period only, even in the event of a continuously asserted manual reset. The MAX6467US44D3+T significantly improves system reliability compared to traditional manual reset supervisory circuits. The applications of the MAX6467US44D3+T include Cell Phones/PDAs, Embedded Control Systems, Industrial Equipment, Automotive Products, Portable/Battery-Powered Equipment, Medical Devices, DSL Modems, MP3 Players, GPS Systems, Digital Cameras.
