DS1232LPS+T&R

Supervisors Overview

The DS1232LPS+T&R is a Low-Power MicroMonitor Chip manufactured by Analog Devices Inc./Maxim Integrated. It functions as a voltage supervisory circuit designed to monitor system power integrity. The device operates within a supply voltage range of 3.0 V to 5.5 V and features a quiescent current of 200 uA. It provides active high, active low, and open drain output types with a reset delay time of 610 ms. The component includes watchdog timer functionality and power-fail detection capabilities. It is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates watchdog timer for automatic microprocessor restart after fault conditions
• Provides power-fail detection to ensure reliable system monitoring during voltage drops
• Offers flexible output configurations including active high, active low, and open drain signals

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the tape-and-reel packaging format aligns with automated assembly requirements. Cross-reference the exact part number with authorized distributors to confirm availability status and lead times prior to procurement planning.

Supervisors Selection Notes

Select this component when low quiescent current consumption is critical for battery-operated or energy-efficient designs. The integrated watchdog feature simplifies software complexity by handling hardware resets automatically. Verify that the required reset threshold voltage falls within the specified operational range of the target application environment.
