3-Phase Gate Driver IC

ECN30531F
The ECN30531 drives a 3-Phase Motor Bridge with 3 TOP and 3 BOTTOM Arms, Push-Pull Output
Drivers controlled by 6 CMOS inputs. Built in a High Voltage Dielectric Isolation Process, this Latch-Up
Free IC can directly drive 6 IGBT or MOSFET gates in 3-Phase Brushless DC and Induction Motor
Bridges. The TOP Arms can Boot Strap bias at up to 620VDC (Breakdown). An on-chip OpAmp allows
Custom, Low, Over Current (OC) trip voltages to minimize Sense Resistor power dissipation in High
Wattage applications. The TOP and BOTTOM Arms are Under Voltage (UV) protected.
