DS1236A-5N+

Supervisors Overview

The DS1236A-5N+ is a MicroManager integrated circuit designed for power supply monitoring and backup control in microprocessor systems. It operates within a commercial temperature range of 0°C to 70°C and is housed in a 16-pin DIP package. The device monitors a single voltage channel with a threshold of 4.37V, providing both open-drain and push-pull outputs. It features a minimum reset timeout of 25 ms and supports active-high or active-low reset signals. The component consumes less than 100 nA of battery current at 25°C, ensuring efficient operation during power failure events.

Supervisors Feature Summary

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

Supervisors Applications

• Nonvolatile microprocessor applications requiring orderly shutdown
• Battery-operated handheld applications needing low-power stop mode control
• High-current applications controlled via external power switches
• Systems requiring accurate power supply monitoring and backup management

Supervisors Procurement Notes

Verify the specific suffix 'N' corresponds to the 16-pin DIP package configuration as indicated in official documentation. Confirm that the '+T&R' suffix variant differs only in packaging format while maintaining identical electrical characteristics. Ensure compatibility with the required operating temperature range of 0°C to 70°C for commercial applications. Cross-reference the manufacturer's latest datasheet to confirm pinout assignments and output drive capabilities before integration.

Supervisors Selection Notes

Select this component when precise 10% power supply monitoring is required alongside comprehensive backup management functions. The DS1236A-5N+ is suitable for designs needing both reset generation and direct control over external switching elements for SRAM backup. Consider the 16-pin DIP package if through-hole mounting is preferred for prototyping or specific mechanical constraints. Evaluate the low standby current consumption for battery-sensitive applications where minimal drain during normal operation is critical.

Supervisors Part Context

The DS1236 series belongs to Maxim Integrated's MicroManager family, which integrates power supply monitoring, reset generation, and backup control into a single chip. This series simplifies the design of nonvolatile memory systems by eliminating discrete components typically used for power supervision and battery switchover. The DS1236A-5N+ specifically offers a fixed threshold version, distinguishing it from adjustable variants within the broader product line.

Supervisors Replacement Considerations

The DS1236S-10+T&R serves as a functional substitute with identical electrical specifications but utilizes a 16-SOIC surface-mount package instead of the DIP form factor.
