DS1232LPS-2/T&R

Supervisors Overview

The DS1232LPS-2/T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input within a 4.5V to 5.5V range, featuring selectable thresholds of 3.3V to 5.5V. The device provides active high, active low, and open drain outputs with a reset delay time of 610 ms. It includes a watchdog timer and power-fail detection, operating at a maximum supply voltage of 5.5V and consuming 200 µA. The component is housed in an SOIC-8 package and supports surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for program execution monitoring
• Provides configurable output types including active high, active low, and open drain
• Includes power-fail detection capability for system reliability

Supervisors Applications

• Embedded systems requiring microprocessor supervision
• Industrial control units needing watchdog protection
• Communication equipment power management

Supervisors Procurement Notes

Verify the exact suffix designation as datasheets may list DS1232LPS-2+T&R or similar variants. Confirm RoHS compliance status through official manufacturer documentation, as older Maxim parts may have specific environmental declarations. Ensure the tape and reel packaging matches your automated assembly requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. Verify that the 200 µA operating current fits the system's power budget. Ensure the SOIC-8 package dimensions align with the PCB footprint constraints and that the 610 ms reset delay meets the target microcontroller's startup timing specifications.

Supervisors Part Context

This part belongs to the DS1232LP/S series of low-power MicroMonitor chips originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. These circuits are designed to provide robust reset signals and watchdog timers for embedded applications, ensuring system stability during power fluctuations or software faults.
