LTC2966CSW#PBF

Supervisors Overview

The LTC2966CSW#PBF is a low current, high voltage dual channel voltage monitor manufactured by Analog Devices Inc. It monitors two independent voltages and provides configurable under-voltage and over-voltage detection. The device features internal high-value resistors for sensing input monitor pins, enabling a compact design. It operates within a supply voltage range of 2.5 V to 36 V and supports adjustable or selectable voltage thresholds. The component offers open drain or open collector outputs and includes manual reset functionality. It is housed in a 20-SOIC package and functions within an operating temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Dual channel voltage monitoring with configurable under-voltage and over-voltage detection capabilities
• Internal high-value resistors provide compact sensing for input monitor pins without external components
• Supports adjustable or selectable voltage thresholds for flexible system supervision requirements

Supervisors Applications

• Power-system supervision in safety-critical automotive applications
• Monitoring multiple independent voltage rails in embedded systems
• High voltage circuit protection where low quiescent current is required

Supervisors Procurement Notes

Verify the specific suffix CSW indicates the commercial temperature grade and SOIC package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the open drain/open collector output configuration matches the downstream logic interface requirements. Validate that the 36 V maximum input rating exceeds the highest expected system voltage during transient conditions.

Supervisors Selection Notes

Select this component when dual-channel supervision is required within a single package footprint. The internal resistor network reduces external bill of materials compared to discrete solutions. Consider the 0°C to 70°C operating range against environmental constraints. Verify that the adjustable threshold feature meets the specific trip point accuracy needs of the application design.

Supervisors Part Context

This part belongs to the LTC2966 series of voltage monitors from Analog Devices. It complements other supervisory ICs by offering dual-channel capability in a standard surface-mount package. The series focuses on high-voltage tolerance and low power consumption for industrial and automotive environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the LTC2966CTS8-4#TRMPBF for different packaging or channel configurations. Verify electrical parameter equivalence before substitution.
