LTC2935IDC-4#TRMPBF

Supervisors Overview

The LTC2935IDC-4#TRMPBF is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a reset output when the supply drops below or rises above specific thresholds. The device features selectable threshold voltages, with the -4 suffix indicating a fixed threshold configuration. It operates within an input voltage range of up to 5.5 V and consumes only 500 nA of quiescent current. The component offers 1.5% accuracy and includes a manual reset capability with a 200 ms reset delay time. It is housed in an 8-lead DFN package suitable for surface mount applications.

Supervisors Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Selectable threshold voltage options for precise monitoring
• Manual reset functionality with defined delay timing
• High accuracy voltage supervision at 1.5%

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing reliable voltage supervision
• Industrial control circuits with strict power constraints

Supervisors Procurement Notes

Verify the exact part number including the suffix to ensure correct threshold voltage selection. Confirm package type matches design requirements. Check RoHS compliance status before integration. Ensure availability through authorized distributors as stock levels vary. Validate datasheet specifications against application needs.

Supervisors Selection Notes

Choose this supervisor for applications requiring minimal quiescent current and high accuracy. Consider the fixed threshold option if no external resistor network is desired. Evaluate thermal performance within the specified operating temperature range. Compare pinout compatibility with existing PCB layouts. Assess reset delay requirements against system startup times.

Supervisors Part Context

This component belongs to the LTC2935 family of voltage supervisors from Analog Devices. The family offers various packages and threshold combinations. The IDC package denotes an 8-lead DFN form factor. The -4 suffix specifies a particular threshold voltage setting. This series is designed for energy-efficient monitoring tasks.

Supervisors Replacement Considerations

Direct substitutes include other LTC2935 variants with different suffixes for alternative thresholds or packages. Cross-reference pinouts and electrical characteristics carefully. Verify functional equivalence regarding reset behavior and accuracy. Consult manufacturer documentation for approved replacements.
