DS1232LPS+

Supervisors Overview

The DS1232LPS+ is a low-power MicroMonitor voltage supervisor in an 8-SOIC package. It monitors a single input with thresholds of 4.37V or 4.62V selectable via the TOL pin. The device provides active high, active low, and open-drain outputs with adjustable reset timeouts. Operating from 4.5V to 5.5V, it features a watchdog timer and power-fail detection within a 0°C to +70°C temperature range.

Supervisors Feature Summary

• Integrates power-fail comparator for monitoring supply voltage deviations
• Configurable watchdog timer with programmable timeout intervals
• Selectable reset output polarity and open-drain capability
• Manual reset input support for system intervention

Supervisors Applications

• Microprocessor power supply supervision
• Watchdog timer implementation in embedded systems
• Power-fail signal generation for data protection

Supervisors Procurement Notes

Verify RoHS compliance status as datasheets may indicate conflicting information regarding REACH and RoHS3 certification. Confirm package variant accuracy against specific suffix requirements. Check manufacturer discontinuation notices for legacy stock availability. Validate operating temperature range specifications against application environmental constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with configurable watchdog functionality is required. Ensure the 8-SOIC package fits the PCB layout constraints. Verify that the 4.5V to 5.5V operating range matches the target system voltage. Consider the TOL pin configuration for threshold selection between 4.37V and 4.62V based on system tolerance requirements.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for microprocessor supervision. The DS1232 series provides integrated power management functions including reset generation and watchdog timing. This specific model represents the lead-free, RoHS-compliant version of the legacy DS1232LPS part number.

Supervisors Replacement Considerations

DS1232LPSN+ offers similar functionality in a 16-pin SOIC package.
