DS1232SN

Supervisors Overview

The DS1232SN is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and monitors a single input channel. The device features a watchdog timer, power-fail detection, and manual reset capability. Reset delay times are specified at 610 ms or 1 s depending on configuration. It supports active high, active low, open drain, and push-pull output types with 10% accuracy. Operating temperatures range from -40°C to +85°C in an SOIC-16 package.

Supervisors Feature Summary

• Integrates a watchdog timer for program execution monitoring
• Provides configurable power-fail detection signals
• Supports multiple output drive configurations including open drain and push-pull

Supervisors Applications

• Microprocessor system supervision
• Industrial control unit protection
• Embedded system power monitoring

Supervisors Procurement Notes

Verify the specific suffix requirements against the official datasheet to ensure correct threshold voltages and reset timing characteristics. Confirm package availability as distribution status may vary by region. Cross-reference manufacturer part numbers to avoid confusion with similar variants in the MicroMonitor family.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. Ensure the operating temperature range meets environmental specifications. Verify that the available output drive types match the interface requirements of the target microprocessor or logic circuitry.

Supervisors Part Context

This part belongs to the DS1232 series of MicroMonitor circuits originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. These devices are designed to provide reliable reset signals and system protection for embedded applications requiring robust power management supervision.

Supervisors Replacement Considerations

DS1232SN+T&R is a reel variant of the same functional device.
