Fairchild Semiconductor’s New Gate Driver Optocoupler Provides Designers High Insulation Voltage and High Noise Immunity
News Release from:
08 May 2012
High power industrial applications such as solar inverters, uninterruptible power supplies (UPS) and motor drives demand a gate driver optocoupler capable of handling networks greater than 690VAC and constant DC voltages greater than1000VDC. In order to achieve this, a creepage and clearance distance of 10mm or greater is essential.
Similarly, applications such as Harsh Environment Inverters (HEI) also require wider creepage and clearance distances even with a 690VAC network. To help designers meet this challenge, Fairchild Semiconductor developed the FOD8320, an advanced 2.5A Output Current Gate Driver Optocoupler.
Using Fairchild’s Optoplanar® packaging technology and optimized IC design, the FOD8320 optocoupler achieves reliable and high insulation voltage as well as high noise immunity. The device, housed in a wide body 5-pin small outline package, offers a compact footprint while allowing for a creepage and clearance distance greater than 10mm and 0.5mm internal insulation distance. Additionally, the FOD8320 provides an extended industrial temperature range (-40 to +100ºC) and is ideally suited for fast switching of power IGBTs and MOSFETs used in industrial inverter applications. Designed with 35kV/µs minimum Common Mode Noise Rejection (CMR) resulting from the proprietary Optoplanar coplanar packaging technology, the FOD8320 eliminates the capacitive charge buildup that occurs in the over-under construction.
Features and Benefits:
• 10mm minimum creepage and clearance distance
• P-Channel MOSFETs at output stage enables output voltage swing close to the supply rail
• Wide supply voltage range from 15V to 30V
• Fast switching speed over full operating temperature range
‾ 400ns max. propagation delay
‾ 100ns max. pulse width distortion
• Under Voltage Lockout (UVLO) with hysteresis
• Extended industrial temperate range, -40 to 100°C temperature range
