LTC2935IDC-4

Supervisors Overview

The LTC2935IDC-4 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 a specific threshold. The device features an active-low, open-drain reset output with a fixed 140ms minimum reset delay time. It operates within a supply voltage range of 1.2V to 5.5V and consumes only 500nA of quiescent current. The component is housed in an 8-lead DFN package and supports manual reset functionality via an external pin.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Configurable threshold voltage selection for precise monitoring
• Manual reset capability allows system initialization control

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power-fail detection
• Industrial equipment utilizing multi-source energy harvesting

Supervisors Procurement Notes

Verify the specific suffix IDC-4 against official Analog Devices documentation to confirm the exact threshold voltage combination and package type. Ensure compatibility with the target operating temperature range of 0°C to +70°C. Confirm RoHS compliance status through the manufacturer's material declaration before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with ultra-low standby current is required. The IDC-4 variant offers a specific threshold configuration distinct from other suffixes. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the 140ms reset delay against system startup timing requirements.

Supervisors Part Context

This part belongs to the LTC2935 family of voltage supervisors designed for low-power applications. The family includes various packages such as SOT-23-8 and DFN, with different threshold options. The IDC-4 specifically denotes the 8-lead DFN package variant with a defined threshold set, distinguishing it from TSOT-23-8 or other threshold codes.

Supervisors Replacement Considerations

Direct substitutes include other LTC2935 variants with compatible packages and thresholds, such as LTC2935CDC-4#TRPBF or LTC2935ITS8-4#TRMPBF, provided the electrical characteristics match the design requirements.
