HIGH-VOLTAGE MONOLITHIC IC
ECN3063
ECN3063 is monolithic IC integrating 6 IGBTs.
It can be applied to DC brushless motors.
Functions
* Integrated charge pump circuit
* Free Wheeling Diodes are integrated
* Overcurent Protection circuit is integrated
Features
* PWM control of uper and bottom arm IGBTs are possible by controlling
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 230V power supplies

Note 1.
Note 1.
Note 1.
Clock frequency is determined approximately by next equation.
Floating capacitance of PCB must be considered.
At Recommended Value of CR, the error factor of IC is about 10%.
fclock = -1 / (2C*R*Ln(1-3.5/5.5)) ; Ln is natural logarithm
= 0.494 / (C*R) (Hz)
Note 2. Current is limited by the following equation.
IO = Vref / Rs (A)
