Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

FAN7384
Half-Bridge Gate-Drive IC
Features
Description
 Floating Channel for Bootstrap Operation to +600V
The FAN7384 is a monolithic half-bridge gate-drive IC
designed for high voltage, high speed driving MOSFETs
and IGBTs operating up to +600V.
 Typically 250mA/500mA Sourcing/Sinking Current


Driving Capability for Both Channels
Extended Allowable Negative VS Swing to -9.8V for
Signal Propagation at VDD=VBS=15V
Matched Propagation Delay Below 50ns
Output In-Phase with Input Signal
3.3V and 5V Input Logic Compatible
Built-in Shoot-Through Prevention Logic
Built-in Common Mode dv/dt Noise Canceling Circuit
Built-in UVLO Functions for Both Channels
Built-in Cycle-by-Cycle Shutdown Function
Built-in Soft-Off Function
Built-in Bi-Directional Fault Function
Built-in Short-Circuit Protection Function
Fairchild’s high-voltage process and common-mode
noise canceling technique provide stable operation of
high-side drivers under high-dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gate
driver operation up to VS = -9.8V (typical) for VBS =15V.
The UVLO circuits prevent malfunction when VDD and
VBS are lower than the specified threshold voltage.
Output drivers typically source/sink 250mA/500mA,
respectively, which is suitable for half-bridge and fullbridge applications in motor drive systems.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. TA=25°C, unless otherwise specified.

1. Protection Function
HIN/LIN
1.1 Under-Voltage Lockout (UVLO)
The high- and low-side drivers include under-voltage
lockout (UVLO) protection circuitry that monitors the
supply voltage (VDD) and bootstrap capacitor voltage
(VBS) independently. It can be designed to prevent
malfunction when VDD and VBS are lower than the
specified threshold voltage. Moreover, the UVLO
hysteresis prevents chattering during power supply
transitions. If the supply voltage (VDD) maintains an
under-voltage condition over under-voltage filtering times
(typically 16µs), the fault and soft-off circuits are
activated, as shown Figure 34.

FAN7384 — Half-Bridge Gate-Drive IC
Typical Application Information
2.2 Gate-Drive Loop
For optimum performance, considerations must be taken
during printed circuit board (PCB) layout.
Current loops behave like antennae, able to receive and
transmit noise. To reduce the noise coupling/emission
and improve the power switch turn-on and off performance, gate-drive loops must be reduced as much as
possible.
2.1 Supply Capacitors
If the output stages are able to quickly turn on a switching device with a high value of current, the supply capacitors must be placed as close as possible to the device
pins (VDD and GND for the ground-tied supply, VB and
VS for the floating supply) to minimize parasitic inductance and resistance.

FAN7384 Rev. 1.0.8
2.3 Ground Plane
To minimize noise coupling, the ground plane should not
be placed under or near the high-voltage floating side.
