in CB. Incidentally, in case of start-up and so on, when the voltage of CB is low, the big charging
electric current flows and sometimes becomes the cause which exerts the bad influence of the noise
and so on. Put limitation resistance RB (Several Ω to about tens of Ω). (When not using bootstrap
circuit, each upper side pre-drive power supply needs an independent power supply. Externally set.)
Also, the upper side power supply voltage sometimes declines by the way of controlling. Confirm it.
2. Because the jump voltage which is accompanied by the vibration in case of switching operation
occurs by the influence of the floating inductance of the wiring of the outer power supply which is
connected with of the + terminal and the –terminal, restrains and spares serge voltage being as the
connection of the snubber circuit (Capacitor / CS / about 0.1 - 10 µF) for the voltage absorption with
the neighborhood as possible between + and the - terminal, and so on, with making a wiring length
(among the terminals each from CI) short and making a wiring inductance small.
3. Iso terminal (20pin) is for the electric current monitor. Be careful, because the overcurrent protection
does not operate when short-circuiting in the Iso terminal and the Vss terminal.
4. Output form of the FAULT terminal is open DRAIN (it is operating as FAULT when becoming LOW).
When the pull up with the resistance, use above 5.6KΩ.
5. Zener diode with 5V (5.0-5.4V) is connected with the inside of the signal input terminal. When
inputting the voltage which exceeds 5 V, connect resistor to between the side of the power and the
signal input terminal, for the input current of the signal input terminal become equal to or less than
0.5mA. This resistor is effective with the noise absorption of the signal terminal, too.
6. The overcurrent protection feature operates only when it is possible to do a circuit control normally.
For the safety, put a fuse, and so on in the Vcc line.
7. Because the IC sometimes destroys and bursts when motor connection terminal (3pin,6pin,9pin)
becomes open while the motor turns, especially, be careful of the connection ( the soldering
condition ) of this terminal.
