Solutions for High-Voltage Applications
Advantages
• 10mm minimum creepage and
clearance distance (FOD8320)
• 8mm minimum creepage and
clearance distance (FOD8321)
• Use of P-channel MOSFETs
at output stage enables output
voltage swing close to the
supply rail
• Fast switching speed over full
operating temperature range
• 400ns max. propagation
delay (FOD8320)
• 100ns max. pulse wide
distortion (FOD8320)
• Under Voltage Lockout
(UVLO) with hysteresis
• Extended industrial
temperate range:
–40°C to 100°C
Applications
• AC and brushless
DC motor drives
• Industrial inverters
• Uninterruptible power
supplies (UPSs)
• Induction heating
• Isolated IGBT/Power
MOSFET gate drivers
High-Voltage Insulation Reliability
in Small Form Factor
Achieve reliable and high-insulation voltage as well as high-noise immunity in
high-power industrial applications with Fairchild’s FOD8320 and FOD8321,
advanced 2.5A current output gate driver optocouplers. Utilizing Fairchild’s
Optoplanar^® packaging technology and optimized IC design, both devices
are housed in a wide body 5-pin small outline package. The FOD8320
offers a compact footprint while allowing for a creepage and clearance
distance of greater than 10mm and an internal insulation distance of
0.5mm. The FOD8321 is an alternative for customers who do not require
the 10mm creepage and clearance distance but need the small form factor.
Both devices provide an extended industrial temperature range
(-40°C to 100°C) and are well suited for fast switching of power IGBTs and
MOSFETs used in industrial inverter applications.
