Diodes Incorporated DGD0507AFN-7

Overview

DGD0507AFN-7 from Diodes Incorporated is a high-frequency dual-channel gate driver IC for half-bridge N-channel MOSFET configurations, featuring 50V floating high-side capability, 1.5A source / 2.0A sink output current, 20ns typical propagation delay, and integrated bootstrap diode - deployed in DC-DC converters, motor control, and Class D amplifiers.

For engineers reviewing the DGD0507AFN-7 datasheet, DGD0507AFN-7 pinout, DGD0507AFN-7 application, or DGD0507AFN-7 equivalent, key selection criteria include high-side UVLO threshold (7.0V typ), delay matching (5ns typ), logic-level compatibility down to 3.3V, thermal performance (RθJA = 64°C/W), and W-DFN3030-10 package suitability for space-constrained power stages.

Technical Context

The DGD0507AFN-7 implements independent high-side and low-side drivers with cross-conduction prevention logic to enforce dead-time between HO and LO outputs. Its floating high-side stage supports VS up to +50V relative to COM and withstands dVS/dt transients up to 50 V/ns.

It integrates a bootstrap diode to simplify high-side supply design and employs separate undervoltage lockout (UVLO) circuits for both VCC and VB supplies, with hysteresis (0.4V for VCCUV, 0.1V for VENINHYS) to prevent oscillation near threshold.

FAQ

What is the maximum allowable dVS/dt for the DGD0507AFN-7 high-side driver?

The DGD0507AFN-7 specifies a maximum offset supply transient rate of 50 V/ns for the VS node. This rating ensures reliable operation under fast-switching conditions in half-bridge topologies without false triggering or latch-up. Exceeding this limit may compromise timing accuracy or cause unintended high-side conduction.

Can the DGD0507AFN-7 drive both high-side and low-side MOSFETs simultaneously in phase?

No - the DGD0507AFN-7 incorporates hardware-level cross-conduction prevention logic that enforces mutual exclusivity between HO and LO outputs. Even if HIN and LIN are driven identically, internal timing control guarantees a minimum dead-time, preventing shoot-through during transitions.

Is the NC pin (Pin 2) required to be grounded or left floating on the PCB?

Pin 2 is a true no-connect terminal with no internal bond wire or silicon connection. It must remain unconnected on the PCB - neither grounded nor tied to any net. Routing copper or solder paste to this pad may risk shorting adjacent pins due to the 0.5mm pitch in the W-DFN3030-10 package.

Does the DGD0507AFN-7 support 3.3V-only logic inputs without external level shifting?

Yes - all logic inputs (HIN, LIN, EN) accept 3.3V-compatible TTL/CMOS levels, with VIH(min) = 2.4V and VIL(max) = 0.8V at VCC = 12V. The device operates correctly with 3.3V microcontrollers directly, provided VCC remains ≥8V per recommended operating conditions.
