LTC2914CDHC-1#PBF

Supervisors Overview

The LTC2914CDHC-1#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent channels capable of detecting both under-voltage and over-voltage conditions on positive and negative supplies. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 70µA. It is housed in a compact 16-lead DFN package, suitable for surface-mount assembly.

Supervisors Feature Summary

• Provides simultaneous monitoring of four distinct voltage rails with independent threshold settings
• Detects both under-voltage and over-voltage events across positive and negative power supplies
• Integrates an internal reset generator with programmable delay and manual reset capability

Supervisors Applications

• Multi-rail power sequencing in industrial equipment
• Voltage supervision in telecommunications infrastructure
• System integrity monitoring in embedded computing platforms

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and functional compatibility. Confirm RoHS compliance status through authorized distributors. Ensure the DFN-16 package variant matches your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems requiring comprehensive supervision of multiple power rails within a limited board area. The quad-channel architecture reduces component count compared to discrete solutions. Verify that the required voltage thresholds fall within the adjustable ranges supported by the external resistor network configuration.

Supervisors Part Context
