The device is housed in a compact 10-DFN (3x2) package, suitable for surface mount applications. It provides open drain or open collector output options for flexible system integration.

Supervisors Feature Summary

• Integrates 27 selectable voltage threshold combinations for customizable supervision
• Includes built-in watchdog timer functionality for system reliability
• Offers open drain or open collector output configurations

Supervisors Applications

• Embedded system power monitoring
• Industrial control unit supervision
• Consumer electronics voltage oversight

Supervisors Procurement Notes

Verify the specific suffix A1 to confirm the selected threshold configuration matches design requirements. Confirm the 10-DFN (3x2) package dimensions against PCB layout constraints. Ensure compatibility with the required output type, as the device supports both open drain and open collector options depending on implementation.

Supervisors Selection Notes

Select this component when multiple fixed voltage thresholds are needed without external resistors. The integrated watchdog timer reduces external component count compared to basic supervisors. Consider the 10-DFN package size for space-constrained designs requiring high precision voltage monitoring capabilities.

Supervisors Part Context

This part belongs to the LTC2918 series of voltage supervisors from Analog Devices. The series is designed for applications requiring reliable power management with minimal external components. The HDDB suffix indicates the DFN package type, while the A1 designation specifies the internal threshold selection code.
