Fault output signal pull-up resistor (Note 3)
1) Input drive is active-high type. There is a 2.5k
7(min.) pull-down resistor integrated in the IC input circuit. To prevent malfunction, the wiring
of each input should be as short as possible. When using RC coupling circuit, make sure the input signal level meets the turn-on and turn-off
threshold voltage. See application notes for details.
2) Internal HVIC provides high voltage level shifting allowing direct connection of all six driving signals to the controller.
3) FO output is an open collector type. Pull up resistor (R3) should be adjusted to current sink capability of the controller.
4) To prevent input signal oscillations, minimize wire length to controller (~2cm). Additional RC filtering (C5 etc.) may be required. If filtering is added
be careful to maintain proper dead time and voltage levels. See application notes for details.
5) All capacitors should be mounted as close to the terminals as possible. (C1: good temperature, frequency characteristic electrolytic type,
and C2, C3: good temperature, frequency and DC bias characteristic ceramic type are recommended.)
6) Shows short circuit protection disabled. See application notes for use of short circuit protection.
7) Local decoupling frequency filter capacitors must be connected as close as possible to the module’s pins.
8) The length of the DC link wiring between C5, C6, the DIP’s P terminal and the shunt must be minimized to prevent excessive transient
voltages. In particular C6 should be mounted as close to the DIP as possible.
9) Use high quality, tight tolerance current sensing resistor. Connect resistor as close as possible to the DIP’s N terminal. Be careful to check
for proper power rating. See application notes for calculation of resistance value.
10) Inserting a Zener diode (24V/1W) between each pair of control supply terminals to prevent surge destruction is recommended.
