onsemi NCx57081 IGBT/MOSFET Gate Drivers

onsemi NCx57081 IGBT/MOSFET Gate Drivers are high-current single-channel IGBT/MOSFET gate drivers with 3.75kV_RMS internal galvanic isolation. These drivers accept complementary inputs and offer options such as active miller clamp, negative power supply, and separate high/low driver outputs for system design convenience. The NCx57081 drivers accommodate a wide range of input bias voltage and signal levels from 3.3V to 20V and are available in a narrow-body SOIC-8 package. Typical applications include motor control, Uninterruptible Power Supplies (UPS), automotive applications, industrial power supplies, solar inverters, and HVAC.

Features

Short propagation delays with accurate matching
IGBT/MOSFET gate clamping during short circuit
IGBT/MOSFET gate active pull-down
Tight UVLO thresholds for bias flexibility
Wide bias voltage range including negative VEE2 (version B)

High transient immunity
High electromagnetic immunity
Low clamp voltage drop eliminates the need for negative power
supply to prevent spurious gate turn-on (version A)
