High Voltage ICs | PRODUCT FAMILIES<br />
HVIC Backround Information<br />
• High voltage integrated circuit (HVIC)<br />
drivers are driver ICs that receive an<br />
input signal from a control IC, amplify<br />
this signal, and drive one or more<br />
switches (MOSFET or IGBT).<br />
• Many <strong>power</strong> conditioning applications<br />
(e.g. lighting, motor control, etc.) require<br />
one or more devices to be switched<br />
between high voltage rails. These<br />
applications require some form of high<br />
voltage level-shifting technology.<br />
• <strong>International</strong> <strong>Rectifier</strong>’s proprietary<br />
high voltage level-shifting technology<br />
provides the required level-shifting for<br />
these applications in a compact, robust,<br />
and cost-effective design.<br />
High Voltage Gate Driver ICs (HVICs)<br />
<strong>International</strong> <strong>Rectifier</strong>'s MOSFET and IGBT gate driver ICs are the simplest, smallest and<br />
lowest cost solution to drive MOSFETs or IGBTs up to 1200V in applications up to 12kW,<br />
and can save over 30% in part count in a 50% smaller PCB area compared to a discrete<br />
opto-coupler or transformer-based solution. With the addition of few external components,<br />
IR gate driver ICs provide full driver capability with extremely fast switching<br />
speeds, designed-in ruggedness and low-<strong>power</strong> dissipation.<br />
Gate driver IC's generate the current and voltage necessary to turn MOSFETs or IGBTs on<br />
and off from the logic output of a DSP, micro-controller or other logic device. The input is<br />
typically a 3.3 volt logic-level signal. All IR gate driver ICs are CMOS compatible, and most<br />
are TTL compatible. Output currents are up to 2A.<br />

High Voltage<br />
Rails<br />
Driving a MOSFET or IGBT in the high side position of a half-bridge topology or 3-phase<br />
inverter leg offers the additional challenge that the gate voltage is referenced to the<br />
source rather than to ground. The source voltage<br />
is a floating point at up to the maximum bus<br />
voltage, or voltage rating of the MOSFET or<br />
IGBT, 600V and up for motor drive, lighting or<br />
SMPS applications. IR gate drivers use a<br />
patented level shifter technology for high voltage<br />
applications and offer the only 1200 V rating<br />
in the industry.<br />
