DS1238S-10

Supervisors Overview

The DS1238S-10 is a MicroManager integrated circuit designed for power management and system protection in microprocessor applications. It operates within a temperature range of 0°C to 70°C and utilizes a 16-SOIC surface-mount package. The device monitors a single voltage supply with a threshold of 4.37V, providing high-active or low-active reset outputs with a minimum timeout of 40 ms. It features both open-drain and push-pull output configurations.

Supervisors Feature Summary

• Holds the microprocessor in check during power transients and halts out-of-control processors
• Converts CMOS SRAM into nonvolatile memory by controlling external power switches
• Unconditionally write-protects memory when the power supply is out of tolerance

Supervisors Applications

• Microprocessor system power monitoring
• CMOS SRAM nonvolatile memory conversion
• Orderly shutdown control in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'S-10' against official Maxim Integrated documentation to confirm the exact pinout, temperature grade, and packaging specifications. Ensure compatibility with the target 16-SOIC footprint and validate that the 4.37V threshold aligns with the system's voltage requirements before procurement.

Supervisors Selection Notes

Select this component for applications requiring precise power supervision and battery backup management. It is suitable for designs needing accurate power-failure warnings and automatic write-protection mechanisms. Consider the 16-SOIC package constraints and the specified operating temperature range when integrating into the final hardware design.

Supervisors Part Context

This part belongs to the DS1238 MicroManager family, which integrates power-supply monitoring, battery-switchover, and watchdog timer functions. It is designed to replace discrete components in complex power management circuits, offering a compact solution for maintaining system integrity during power fluctuations.

Supervisors Replacement Considerations

The MAX691 is documented as a pin-for-pin compatible alternative within the same product family.
