LTC2964IUDC#TRPBF

Supervisors Overview

The LTC2964IUDC#TRPBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It monitors four independent power supply rails simultaneously within an operating voltage range of 2.5 V to 5.5 V. The device provides high threshold accuracy of ±0.5% across the entire industrial temperature range. It features selectable under-voltage thresholds for standard voltages including 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, and 1V, alongside an adjustable option. The IC supports both open-drain and push-pull output configurations with a manual reset input and adjustable reset timeout.

Supervisors Feature Summary

• Simultaneous monitoring of four independent power supply channels
• High precision threshold accuracy maintained across the full operating temperature range
• Configurable output drive modes supporting both open-drain and push-pull topologies

Supervisors Applications

• Multi-rail power management systems in embedded controllers
• Industrial equipment requiring simultaneous supervision of multiple voltage domains
• Communication infrastructure monitoring critical power rails

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm the IUDC package designation corresponds to the required 20-lead QFN footprint for your PCB layout. Ensure the selected variant matches the necessary output configuration and threshold settings for your specific power rail requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems that require precise monitoring of four distinct power supplies without external comparator complexity. The fixed selectable thresholds simplify design for common voltage levels like 3.3V and 5V. Consider the adjustable threshold option if non-standard voltages are present. Evaluate the package size constraints against the available 20-QFN form factor during the initial schematic capture phase.

Supervisors Part Context

This part belongs to the LTC2964 series of supervisory circuits designed for multi-channel power monitoring applications. It serves as a compact solution for replacing discrete resistor networks and comparators typically used for voltage detection. The series integrates precision references and delay timers into a single small-footprint package to reduce board space and component count.

Supervisors Replacement Considerations

The LTC2964IUDC#PBF is the tube-packaged equivalent of this reel-supplied component. Verify pinout compatibility if substituting with other quad supervisors from different manufacturers, as threshold selection methods may vary significantly between competing products.
