LTC2914HGN-1#PBF

Supervisors Overview

The LTC2914HGN-1#PBF is a quad voltage monitor from Analog Devices, housed in a 16-lead SSOP package. It monitors four positive and two negative supply voltages with adjustable under-voltage and over-voltage thresholds. The device features a guaranteed threshold accuracy of ±1.5% across the temperature range and includes input interference suppression. Operating supply current is 70 µA, and it provides a buffered 1V reference output.

Supervisors Feature Summary

• Simultaneous monitoring of up to four positive and two negative supply voltages
• Adjustable under-voltage and over-voltage trip points for flexible system configuration
• Guaranteed threshold accuracy of ±1.5% across the full operating temperature range
• Integrated input interference suppression to ensure reliable detection during noisy conditions

Supervisors Applications

• Monitoring multiple power rails in industrial control systems
• Supervising battery packs and power distribution units
• Ensuring voltage stability in telecommunications equipment
• Validating power integrity in automotive electronic modules

Supervisors Procurement Notes

Verify the specific suffix 'HGN' corresponds to the SSOP-16 package variant when sourcing. Confirm that the '-1' designation aligns with the required threshold settings for your application. Ensure compatibility with the 16-lead SSOP footprint during PCB layout. Cross-reference the datasheet revision date to confirm feature consistency. Validate that the component meets RoHS compliance requirements for your region.

Supervisors Selection Notes

Select this part when simultaneous supervision of multiple positive and negative voltages is required. Consider the ±1.5% accuracy specification for precision applications. Evaluate the 70 µA supply current against low-power design constraints. Verify that the SSOP-16 package fits within the available board space. Assess the need for adjustable thresholds versus fixed alternatives.

Supervisors Part Context

This component belongs to the LTC2914 series of supervisory circuits designed for comprehensive power management. It complements other Analog Devices voltage monitors by offering dual inputs per channel for enhanced noise immunity. The series supports various packages including DFN and MSOP options for different form factor requirements.

Supervisors Replacement Considerations

Direct substitutes include the LTC2914HGN-1#TRPBF for tape-and-reel packaging. The LTC2914HDHC-1#PBF offers the same functionality in a DFN-16 package. Verify pinout compatibility before swapping between SSOP and DFN variants.
