VT1697SCFQR Half Bridge Driver - Equivalent & Substitute Parts

Part Overview

The VT1697SCFQR is a half bridge driver IC designed for general purpose power MOSFET applications. It operates as a PWM-controlled driver for inductive loads with integrated fault protection including current limiting, over-temperature shutdown, short circuit protection, and under-voltage lockout (UVLO). The device is packaged in a 16-pin FCQFN form factor (6x3.75mm).

The VT1697SCFQR is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VT1697SCFQR is determined by strict equivalence across the following critical parameters:

• Output Configuration: Half Bridge topology
• Peak Output Current: 55A
• Supply Voltage Range: 1.71V ~ 1.98V
• Load Voltage Range: 8.5V ~ 14V
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Package Type: 16-FCQFN (6x3.75mm)
• Fault Protection Features: Current Limiting, Over Temperature, Short Circuit, UVLO
• Interface: PWM control

The VT1697SCFQX meets all these criteria and is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) with identical electrical and mechanical specifications. The primary distinction is product status: VT1697SCFQX is active production, whereas VT1697SCFQR is obsolete.

Parameter Comparison
