DS1232LPU/T&R

Supervisors Overview

The DS1232LPU/T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with thresholds of 4.37V and 4.62V. The device features open-drain and push-pull outputs, supporting active high or active low reset signals. It includes an adjustable or selectable reset timeout and operates within a temperature range of 0°C to 70°C. The component is housed in an 8-uMAX/uSOP package.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability
• Provides power-fail detection capability
• Supports configurable reset output polarity

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Battery-powered devices with power monitoring needs

Supervisors Procurement Notes

Verify the exact suffix configuration as datasheets may list variations such as DS1232LPU without the T&R designation. Confirm RoHS compliance status, as some listings indicate non-compliance while others show compliant variants. Ensure the manufacturer source matches Analog Devices or Maxim Integrated specifications before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog is required. Verify that the operating temperature range of 0°C to 70°C meets application requirements. Check if the specific threshold voltages of 4.37V and 4.62V align with the monitored rail. Consider package availability in 8-uMAX format.

Supervisors Part Context

This part belongs to the MicroMonitor series from Analog Devices/Maxim Integrated. It is designed for simple reset and power-on-reset applications. The device integrates multiple supervisory functions into a single chip to reduce board space and component count in embedded designs.
