DS1232LPN+

Supervisors Overview

The DS1232LPN+ is a low-power 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 and features a maximum power supply voltage of 5.5 V with an overvoltage threshold at 5.5 V. The device monitors one input and provides active high, active low, and open drain outputs. It includes a watchdog timer and power-fail detection but lacks manual reset and battery backup switching capabilities. The reset delay time is specified as 610 ms, with an accuracy of 10%. Operating current is 200 uA. It supports through-hole installation in a PDIP-8 package and functions within a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside power-fail detection capabilities.
• Provides versatile output configurations including active high, active low, and open drain signals.
• Designed for low-power operation with a working supply current of 200 uA.

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded systems
• Watchdog timer implementation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details prior to integration. Ensure the PDIP-8 through-hole package matches PCB layout requirements. Validate operating temperature range suitability for the specific application environment. Check for obsolescence or lifecycle restrictions before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. Consider the 610 ms reset delay and 10% accuracy specifications for timing-sensitive designs. The wide operating temperature range makes it suitable for industrial environments. Verify that the lack of manual reset and battery backup aligns with system design constraints.

Supervisors Part Context

This part belongs to the DS1232LP series of low-power MicroMonitor chips. It is distinct from other variants like the DS1232LPS which may feature different packages or manual reset options. The PDIP-8 package distinguishes it from surface-mount alternatives such as the LPU variant. It serves as a dedicated supervisory solution within the Maxim Integrated portfolio.
