DS1232S-IBM

Supervisors Overview

The DS1232S-IBM is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V and features a reset delay time of 610 ms. The device includes an integrated watchdog timer and power-fail detection capabilities. It supports active high, active low, open drain, and push-pull output types. The component is housed in a SOIC-16 surface-mount package and functions with a maximum operating current of 500 uA. It provides 10% accuracy for voltage monitoring across a standard commercial temperature range.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability
• Provides power-fail detection functionality
• Supports multiple reset output configurations

Supervisors Applications

• Microcontroller system supervision
• Power supply monitoring circuits
