MAX693AEPE+

Supervisors Overview

The MAX693AEPE+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 0 V to 5.5 V and features a typical threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device provides a reset delay time of 50 ms and consumes a working power supply current of 100 uA. It includes a watchdog timer, battery backup switchover, and power-fail detection capabilities. The output type is active low push-pull, and it lacks manual reset functionality. The component is housed in a PDIP-16 package and supports through-hole installation.

Supervisors Feature Summary

• Integrates watchdog timer and battery backup switchover for system reliability
• Provides power-fail detection with active low push-pull output
• Features chip enable signal control for power management

Supervisors Applications

• Microprocessor power monitoring
• Computers and controllers
• Intelligent instruments
• Critical microprocessor power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'EPE+' against official Analog Devices documentation to confirm lead-free status and temperature grade. Confirm availability as distribution channels may indicate restricted supply or regional sales limitations. Ensure the PDIP-16 through-hole package matches the target PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated watchdog and battery backup is required. The 4.4 V threshold suits standard 5 V logic systems. Consider the 100 uA quiescent current for power-sensitive designs. Verify that the active low push-pull output drives the target microprocessor reset pin correctly without external pull-ups.

Supervisors Part Context

The MAX693A series serves as a pin-compatible upgrade to earlier MAX693 devices, offering improved performance metrics such as lower supply current and faster chip-enable propagation delay. It belongs to the broader family of microprocessor supervisory circuits designed to ensure stable operation in embedded systems by monitoring voltage levels and managing system resets during power anomalies.
