LTC2964CUDC#PBF

Supervisors Overview

The LTC2964CUDC#PBF is a quad configurable supervisor IC from Analog Devices, designed to monitor multiple voltage supplies in electronic systems. It features 0.5% accurate threshold detection for four independent channels. The device supports open-drain or push-pull outputs and includes a manual reset function with a minimum reset timeout of 160ms. Operating within a temperature range of 0°C to 70°C, it utilizes a 20-WFQFN exposed pad package (3x4 mm) for surface mount installation.

Supervisors Feature Summary

• Quad configurable voltage supervision with high accuracy
• Supports both open-drain and push-pull output configurations
• Includes manual reset capability with defined timeout characteristics

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for complex digital logic boards
• System integrity monitoring in industrial control units

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Request original manufacturer documentation to validate lot traceability and RoHS compliance status prior to finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required with tight accuracy specifications. Ensure the system design accommodates the 20-WFQNC package dimensions and thermal requirements. Verify that the available reset timeout meets the target system's recovery timing constraints.

Supervisors Part Context

This part belongs to the LTC2964 series of supervisory circuits, which are optimized for managing power integrity in multi-voltage environments. It complements other Analog Devices PMIC solutions by providing precise fault detection without requiring external resistors for threshold setting.

Supervisors Replacement Considerations

Direct substitutes include the LTC2962CUD#PBF and LTC2963 variants within the same family, provided pin compatibility and channel counts align with the existing design requirements.
