VT1697SBFQX

Overview

The VT1697SBFQX is a half-bridge driver designed for power MOSFET applications, manufactured by Analog Devices Inc./Maxim Integrated. It operates with a supply voltage range of 1.71V to 1.98V and supports load voltages from 8.5V to 14V. The device features a peak output current of 55A and utilizes a PWM interface. It is housed in a 16-FCQFN (6x3.75) surface-mount package. The component functions within a temperature range of -40°C to 125°C TJ and includes integrated fault protection mechanisms such as overcurrent, overtemperature, short circuit, and UVLO.

Feature Summary

• Integrates diode emulation functionality for optimized switching performance.
• Provides status flag outputs for real-time operational monitoring.
• Includes comprehensive fault protection against overcurrent, overtemperature, short circuits, and under-voltage lockout.

Applications

• General-purpose power management systems
• Inductive load driving applications

Procurement Notes

Verify the specific suffix 'X' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the 1.71V to 1.98V supply voltage requirement aligns with your system's logic levels. Ensure thermal management strategies accommodate the 125°C junction temperature limit in high-current scenarios.

Selection Notes

Select this component when a compact half-bridge solution with high peak current capability is required. The low supply voltage range makes it suitable for battery-powered or low-voltage logic-controlled systems. Verify compatibility with the 8.5V to 14V load voltage range before integration into motor control or power conversion circuits.

Part Context

This part belongs to the VT1697 series of smart slave devices and power management ICs from Analog Devices/Maxim Integrated. It is distinct from the VT1677 series, which offers different current ratings and pin configurations. The VT1697 series focuses on efficient half-bridge driving with integrated protection features for robust power stage operation.

Replacement Considerations

Check for direct substitutes within the VT1697 family, such as VT1697SBFQ, ensuring package and electrical specifications match. Cross-reference with other Maxim half-bridge drivers if form-factor constraints allow, verifying pin-to-pin compatibility and thermal performance equivalence.
