DS1239-10

Supervisors Overview

The DS1239-10 is a MicroManager backup power controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75V to 5.5V and features a threshold voltage of 4.37V. The device provides low-active reset output with a minimum timeout of 25ms. Designed for through-hole installation, it utilizes a 16-pin DIP package (0.300 inch width). The component supports an operating temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Monitors pushbutton inputs for external override capabilities
• Converts standard CMOS SRAM into nonvolatile memory configurations
• Provides orderly shutdown control for microprocessor applications

Supervisors Applications

• Nonvolatile microprocessor system management
• Battery-operated handheld device stop mode control
• CMOS SRAM backup power circuit integration

Supervisors Procurement Notes

Verify current manufacturing status as the DS1239-10 is listed as obsolete. Confirm availability of RoHS-compliant alternatives if environmental compliance is required. Check datasheet specifications against legacy design requirements before procurement planning.

Supervisors Selection Notes

Select this component for legacy systems requiring specific MicroManager functionality. Ensure voltage thresholds match the target SRAM backup requirements. Consider package constraints for through-hole mounting in existing PCB layouts.

Supervisors Part Context

Part of the Maxim Integrated MicroManager series designed for battery-backed memory applications. This specific model integrates power monitoring and control logic to manage transitions between main power and backup sources efficiently.

Supervisors Replacement Considerations

DS1239-10+T&R; serves as a tape-and-reel variant of the same functional specification.
