DS1832

Supervisors Overview

The DS1832 is a MicroMonitor Chip designed for 3.3-volt systems, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features a single monitored input with a threshold of 3.3 V. The device includes an integrated watchdog timer and provides active high, active low, and push-pull output types. It offers a reset delay time of 610 ms and maintains an accuracy of 2.5%. Operating currents are specified at 35 uA, with overvoltage thresholds at 2.64 V and 2.97 V. The component supports power failure detection and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Provides multiple output configurations including active high, active low, and push-pull
• Detects power failures without requiring manual reset functionality

Supervisors Applications

• Embedded systems requiring 3.3V supervision
• Industrial control units needing watchdog protection
• Portable devices with limited power budgets

Supervisors Procurement Notes

Verify current availability status as the part may be subject to limited supply or discontinuation. Confirm package type UMAX-8 compatibility with your PCB layout. Ensure operating temperature range meets environmental requirements. Check RoHS compliance details for regulatory adherence. Validate pinout against schematic designs before integration.

Supervisors Selection Notes

Choose this component when a single-channel supervisor with watchdog capability is required for 3.3V rails. Consider the 35 uA quiescent current for low-power applications. Verify that the 610 ms reset delay aligns with system startup timing needs. Evaluate the push-pull output drive strength against load requirements. Compare against alternatives if manual reset inputs are necessary.

Supervisors Part Context

The DS1832 belongs to the Maxim Integrated MicroMonitor family, focusing on simple voltage supervision and system reset generation. It complements other parts like the DS1830 series but differs by integrating a watchdog timer and supporting higher output drive capabilities. This specific model targets cost-sensitive designs requiring reliable power management in compact packages.

Supervisors Replacement Considerations

DS1832S+ serves as a direct pin-compatible alternative in SOIC-8 packaging.
