VT1697SBFQ

Overview

The VT1697SBFQ is a half-bridge driver designed for power MOSFETs, operating with a supply voltage of 1.71V to 1.98V and a load voltage range of 8.5V to 14V. It features a peak output current of 55A and supports PWM interfaces for inductive loads. The device operates within a temperature range of -40°C to 125°C TJ and utilizes a 16-VFQFN (6x3.75) surface-mount package.

Feature Summary

• Integrates diode emulation and status flag capabilities for enhanced system monitoring.
• Includes comprehensive fault protection mechanisms such as current limiting, overtemperature shutdown, short-circuit protection, and under-voltage lockout.

Applications

• General-purpose switching regulator applications
• Boost and Buck converter topologies

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging variations, as the base part number may correspond to different distribution formats. Ensure compatibility with the required thermal management solutions given the QFN package type. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring high peak current drive for external power MOSFETs in compact form factors. The low supply voltage requirement suits battery-powered or low-voltage systems. Evaluate the thermal performance requirements carefully due to the high current capability and small footprint constraints inherent in the 16-QFN package design.

Part Context

This component belongs to the VT1697 series of smart slave devices manufactured by Analog Devices Inc./Maxim Integrated.
