DS1232LPU

Supervisors Overview

The DS1232LPU is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides power supply monitoring with adjustable or selectable reset timeouts and supports active high, active low, or open-drain outputs. The device operates within a voltage range of 4.5V to 5.5V, featuring threshold voltages of 4.37V and 4.62V. It includes a watchdog timer and manual reset capability. The component is housed in an 8-uMAX/uSOP surface-mount package and functions within a temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports configurable reset output polarities including open-drain, active high, and active low
• Provides manual reset functionality via pushbutton input
• Features adjustable or selectable reset timeout durations

Supervisors Applications

• Embedded systems requiring power supervision
• Microcontroller-based designs needing watchdog protection
• Industrial control circuits operating at 5V logic levels

Supervisors Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm if the RoHS-compliant variant DS1232LP+ is available as a direct replacement. Ensure the selected substitute matches the required 8-pin package type and electrical specifications for your design.

Supervisors Selection Notes

Select this component for applications requiring a single-channel voltage monitor with integrated watchdog features. Consider the 8-uMAX package constraints for PCB layout. Verify that the operating temperature range of 0°C to 70°C meets environmental requirements. Check compatibility with the 4.5V to 5.5V supply voltage range.

Supervisors Part Context

This component belongs to the MicroMonitor series from Maxim Integrated, now part of Analog Devices. It is designed for low-power embedded applications. The DS1232LPU specifically utilizes a surface-mount 8-pin uMAX or uSOP package, distinguishing it from through-hole DIP variants like the DS1232LP+.

Supervisors Replacement Considerations

The DS1232LP+ is listed as a direct substitute. Verify package compatibility between the 8-uMAX/SOP and 8-PDIP formats. Confirm RoHS compliance requirements, as the original LPU version is non-RoHS while the LP+ variant complies with ROHS3 standards.
