HIGH-VOLTAGE MONOLITHIC IC
ECN3067
P1/9
ECN3067 is monolithic IC integrating 6 IGBTs.
It can be applied to DC brushless motors and Induction motors.
Functions
• Free Wheeling Diodes are integrated
• Overcurrent Protection Circuit is integrated
• Undervoltage Detection Circuit is integrated
Features
• PWM control of upper and bottom arm IGBTs are
possible with an outer Microprocessor.
• 6 Logic inputs are compatible with 5V CMOS
or LSTTL outputs.
• Upper and Bottom arm IGBTs can operate in 20kHz chopping frequency.
• For converted AC200 to 230 V power supplies PWM control of top and bottom
arm IGBTs are possible.

5.4 Undervoltege Detection
1) When Vcc supply voltage becomes below Vuvb(11.4V typ.), all of the IGBTs shut off and F
terminal output becomes “L”.
2) When between BU-MU, BV-MV or BW-MW voltage become below Vuvt(11.4V typ.), top arm
IGBT of under voltage detected phase shuts off. In this time, F terminal output doesn’t change.
Note 1. When VCC supply voltage becomes lower, driving capability of IGBT also becomes lower.
Accordingly, power dissipation becomes higher and this causes temperature raise of IC.
In case of junction temperature exceeds 135°C, IC may deteriorate or breakdown.
