DS1232SN+

Supervisors Overview

The DS1232SN+ is a MicroMonitor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for microprocessor system supervision. It operates within a supply voltage range of 4.5V to 5.5V and features a reset delay time of 610 ms. The device provides power-fail detection with 10% accuracy and includes an on-chip watchdog timer. It supports active high, active low, open drain, and push-pull output types. The component is housed in a 16-SOIC surface-mount package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates power-supply monitoring, manual reset input, and watchdog timer functionality into a single supervisory circuit.
• Provides configurable reset signal timing with a typical delay of 610 ms upon power recovery.
• Supports multiple output configurations including active high, active low, open drain, and push-pull modes.

Supervisors Applications

• Microprocessor system supervision
• Embedded system power monitoring
• Industrial control unit reset management

Supervisors Procurement Notes

Verify the specific suffix 'SN+' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the 16-SOIC package dimensions match the target PCB footprint. Confirm that the 10% threshold accuracy meets the design requirements for the specific application voltage.

Supervisors Selection Notes

Select this component when a combined solution for power monitoring and watchdog timing is required without external discrete components. The 16-pin SOIC package suits automated surface-mount assembly processes. Verify that the 500 µA operating current aligns with the system's power budget constraints during normal operation.

Supervisors Part Context

The DS1232 series belongs to the MicroMonitor family originally developed by Dallas Semiconductor before its acquisition by Maxim Integrated and subsequently Analog Devices. This line focuses on providing reliable reset generation and system protection for embedded applications, ensuring stability during power fluctuations or software faults.

Supervisors FAQ

Does the DS1232SN+ include a manual reset input?

Yes, the device supports manual reset input functionality alongside its automatic power-on reset and watchdog features.

What is the watchdog timer capability of this IC?

The IC integrates a watchdog timer that can be configured to monitor periodic pulses from the processor, triggering a reset if signals are not received within the specified interval.
