*1. Pre-driver power supply (VD4 = 15±1.5V) must have the capacity of IO = 20mA (DC), 0.5A (Peak).
Usage Precaution
1. By the addition of the diode for the bootstrap (DB : high speed type of trr 100ns or less, withstand voltage equal to or
more than 600V) and of the capacitor (CB : about 1 to 47μF), a single power supply drive is enabled. In this case, it
makes a lower side IGBT ON (input signal of lower side makes LOW).
Then it charges in CB. Incidentally, in case of start-up and so, when the voltage of CB is low, the big charging
electric current flows and sometimes becomes the cause which exerts a bad influence of noise and so on. Put
limitation resistor RB (Several Ω to about tens of Ω).
(When not using the bootstrap circuit, each upper side pre-drive power supply needs an external independent power
supply.)
Also, the upper side power supply voltage sometimes declines by the way of controlling. Please confirm.
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 0.22 - 10μF) 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. When the pull up with the resistance,use above 5.6kΩ 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 5V,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 (2pin, 5pin, 8pin) becomes open
while the motor turns, especially, be careful of the connection ( the soldering condition ) of this terminal.
8. The over current protection feature operates normally when an external resistor RSD is connected between the ISD
and Vss terminals. Be sure to connect this resistor. The Level of the overcurrent protection current is variable
according to the RSD value.Select an RSD resistor of an optimum value
while referring to the formula shown on a separate sheet and connect it between the ISD and VSS terminals.
9. If - terminal and VSS terminal are short-circuited, since an over-current protection (ISD) value will become lower
than the inside setting value of HIC, please do not connect externally.
(–terminal and VSS terminal are connected inside HIC)
