VT1697SBFQR Half Bridge Driver IC

Part Overview

The VT1697SBFQR is a half bridge driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed for general purpose power MOSFET applications. This component operates as a PWM-controlled driver for inductive loads with integrated fault protection including current limiting, over-temperature protection, short circuit detection, and under-voltage lockout (UVLO).

The VT1697SBFQR has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VT1697SBFQR is determined by strict equivalence across the following critical parameters:

• Output Configuration: Half Bridge topology
• Package / Case: 16-VFQFN with 16-FCQFN (6x3.75) supplier device package
• Current - Peak Output: 55A
• Voltage - Supply: 1.71V ~ 1.98V
• Voltage - Load: 8.5V ~ 14V
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Interface: PWM control
• Load Type: Inductive
• Technology: Power MOSFET
• Fault Protection: Current Limiting, Over Temperature, Short Circuit, UVLO
• Features: Diode Emulation, Status Flag
• Mounting Type: Surface Mount

The VT1697SBFQX meets all these criteria and is classified as the manufacturer-recommended substitute.
