Technical overview
Electrical isolation between control logic and power switching stages.
Gate drive optocouplers combine an input LED with an integrated power output stage to provide electrical isolation while driving the gate of IGBT and MOSFET devices. Their higher output voltage and current capability help meet the demanding drive requirements of modern power modules.
Key advantages
Built for noisy, high-voltage power electronics environments.
Rail-to-rail output
Output voltage close to VCC and GND supports lower switching loss in optocoupler-driven IGBT and MOSFET circuits.
UVLO protection
Undervoltage lockout turns off output when supply voltage is insufficient, helping avoid unsafe linear-region operation.
Strong drive capability
High peak output current supports direct drive of demanding power modules, including 1200V / 100A-class IGBT applications.
High noise immunity
CMTI performance up to 35-50 kV/us helps resist switching dV/dt noise and reduce false triggering.
Product matrix
Full current coverage with multiple package choices.
Orient's gate drive optocoupler line covers standard cost-effective drivers and intelligent drivers with additional protection functions such as DESAT detection, soft shutdown, active Miller clamp, and fault feedback.
