DS1236A-5+

Supervisors Overview

The DS1236A-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V, featuring a threshold voltage of 4.5 V to 5.5 V. The device monitors one input and provides active high, active low, open drain, and push-pull outputs. Key specifications include a reset delay time of 150 ms, an overvoltage threshold of 4.5 V, and an undervoltage threshold of 4.25 V. It supports manual reset and includes a watchdog timer and battery backup switch. The component functions with a chip enable signal and power failure detection, drawing 4 mA during operation.

Supervisors Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as the provided model includes a plus sign which may indicate specific compliance or packaging variations not explicitly detailed in general listings. Confirm availability status directly with authorized distributors, as this component series may be subject to discontinuation or limited supply constraints. Ensure the package type matches the required PCB footprint before ordering.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog and battery backup features is required. Consider the 150 ms reset delay and specific threshold voltages for compatibility with the target system's power rails. Verify that the available output types (active high/low, open drain, push-pull) meet the interface requirements of the monitored logic.
