MAX807NCPE+

Supervisors Overview

The MAX807NCPE+ is a full-featured microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5 V to 5.5 V and features a reset threshold voltage of 4.4 V with 2% accuracy. The device provides active high and active low push-pull outputs, a manual reset input, and an integrated watchdog timer. It includes battery backup switching and power-fail detection capabilities. The component is housed in a 16-pin PDIP package and functions reliably across an operating temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Provides dual active high and active low push-pull reset outputs
• Includes manual reset input for user-initiated control
• Features battery backup switching and power-fail detection

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Industrial control systems
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix NCPE against official datasheets to confirm the 16-pin PDIP package and commercial temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list limited stock or obsolete status. Ensure pinout compatibility with existing PCB layouts before integration.

Supervisors Selection Notes

Select this component when a single-supervisor IC with both watchdog and manual reset is required. The 4.4 V threshold suits standard 5 V logic systems. Consider the PDIP package for through-hole prototyping or high-reliability applications requiring robust mechanical mounting. Verify that the 2% accuracy meets the specific voltage tolerance requirements of the monitored rail.

Supervisors Part Context

This part belongs to the MAX807M series of uPower supervisors designed for low-power consumption. It consolidates multiple protection functions into a single small footprint, reducing bill-of-materials complexity compared to discrete solutions. The series is widely used in embedded systems requiring reliable power management and fault handling.

Supervisors Replacement Considerations

Cross-reference with MAX807MCPE+ for identical electrical specifications in the same package. Verify functional equivalence with MAX807NEWE+ if surface-mount packaging is acceptable. Confirm pinout compatibility before substituting with other MAX807 variants.
