*1. Pre-driver power supply (VD4 = 15±1.5V) must have the capacity of IO = 20mA (DC), 0.5A (Peak).
Usage Precaution
1. Single power supply drive is possible by using a bootstrap circuit with a built-in IC.
(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 - 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. 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. 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)
