CT3150
1.0A MOSFET/IGBT Gate Driver Optocoupler
Features
•
•
•
Peak Output Current : IOP = ±1.0A (max)
Threshold Input Current: IFLH = 5 mA (max)
Common mode transient immunity : ±20kV/µs
Description
The CT3150 consists of a GaAsP LED optically
coupled to an integrated circuit with a power output
stage. This optocoupler is ideally suited for driving
power IGBTs and MOSFETs used in motor control
inverter applications. The high operating voltage
range of the output stage provides the drive voltages
required by gate controlled devices.
•
Under voltage lock out (UVLO) protection with
hysteresis
