DS1232+

Supervisors Overview

The DS1232+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V, with a maximum power supply voltage of 5.5 V and an overvoltage threshold of 5.5 V. The device features a reset delay time of 610 ms and maintains an accuracy of 10%. It consumes a working supply current of 500 uA. Designed for through-hole installation, it utilizes an 8-PDIP package. The component supports active high, active low, open drain, and push-pull output types. It includes a watchdog timer but lacks manual reset and battery backup switching capabilities.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports multiple output drive configurations including push-pull and open drain
• Provides power-fail detection capability

Supervisors Applications

• Microprocessor power supervision
• Voltage monitoring in embedded systems
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status as indicated in manufacturer documentation. Ensure the selected package variant matches the required PCB footprint. Validate operating temperature ranges against environmental specifications. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. Consider the 610 ms reset delay and 10% accuracy for timing-sensitive applications. Evaluate the 500 uA supply current against power budget constraints. Verify that the through-hole PDIP-8 package aligns with assembly requirements. Ensure the absence of manual reset meets design logic.

Supervisors Part Context

The DS1232+ belongs to the Maxim Integrated MicroMonitor series, designed for supervising microprocessor power supplies. It combines voltage monitoring with watchdog timer functions in a compact form factor. This series targets applications requiring reliable system reset generation and fault detection without external discrete components.
