Supervisors Procurement Notes

Verify the specific suffix and package variant when ordering, as availability may vary by region. Confirm RoHS compliance status through official documentation before integration. Check for limited supply conditions or discontinuation notices from the manufacturer. Ensure the selected part number matches the required pinout and electrical specifications for your design.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for battery life extension. The adjustable threshold allows customization for various rail voltages without external resistors if supported by the specific variant configuration. Consider the 200 ms reset delay for timing requirements. Verify that the open-drain output interface is compatible with the downstream logic levels in the target application.

Supervisors Part Context

This part belongs to the LTC2934 series of supervisory circuits from Analog Devices. The series offers various packages including DFN and SOT-23-8, with options for fixed or adjustable thresholds. The CDC-1 variant specifically denotes the DFN-8 package with a -1 suffix indicating the adjustable threshold version. It is part of the broader PMIC portfolio focused on power management and system protection.

Supervisors Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements within the same family, such as other LTC2934 variants with different packages or fixed thresholds. Verify electrical parameter compatibility before substitution.
