HVICs (3-Phase, Half-Bridge, and High- & Low-Side Drivers)

Here are some examples of the wide breadth of motor control drivers from Fairchild Semiconductor.

3-Phase Drivers HVIC Features (FAN7389):

Innovative Noise Cancelling Circuit

Floating Channel for Bootstrap Operation to +600V

3.3V and 5V Input Logic Compatible

Lowest quiescent currents = low power consumption

Lowest temperature dependency = stable operation

Built-in Shoot-Through prevention logic

High- and Low-Side Gate Driver HVIC Features (FAN7384):

Floating Channel for Bootstrap Operation to +600V

Typically 250mA/500mA Sourcing/Sinking Current Driving capability for Both Channels

3.3V and 5V Input Logic Compatible

Built-in Shoot-Through prevention logic

Protection Functions: Soft-Off, Bi-Directional fault, Short-Circuit

Low-Side Drivers featuring (FAN3268 and FAN3278):

Dual 2A 20V (FAN3268) or 30V (FAN3278) high-side PMOS, low-side NMOS Bridge Driver with TTL inputs

MillerDrive™ for strong gate drive

<15 ns Typical Rise- and Fall-times

MOSFETs

Features:

Low R_DS(ON)

Low Gate Charge

Fairchild Technology's: SuperFET™, SupreMOS™, UniFET™, PowerTrench™ and FRFET®

SupreMOS® and SuperFET® FRFET® (Fast Recovery Body Diode)

Lower Qrr and Trr

Look for the "F" in the part number; e.g. FCH76N60NF

Ultra FRFET®

SiC diode is no longer needed in anti-parallel with series MOSFET and Schottky diode; while still achieving the same efficiency

Reduce Turn-on loss by 75% compared to standard MOSFETs

Reduced Qrr and Trr, compared to FRFET®, so diode switching loss is drastically reduced

Look for the "U" in the part number; e.g. FDPF5N50NZU

Extensive packaging solutions

Excellent thermal performance

Excellent electrical performance

Fairchild's High Voltage FRFET® MOSFETs
