Note 2) By virtue of integrating a photo-coupler inside the module, direct coupling to CPU, without any extemal opto or transformer isolation is possible. Note 3) All outputs are open collector type. Each signal line should be pulled up to plus side of the 5V power supply with approximately 5.1kΩ resistance. Note 4) The wiring between power DC link capacitor and P/N terminals should be as short as possible to protect the ASIPM against catastrophic high surge voltage. For extra precaution, a small film snubber capacitor (0.1~0.22µF, high voltage type) is recommended to be mounted close to these P and N DC power input pins.

(b) Allowable maximum input on-pulse width : This item applies to both P-side and N-side circuits excluding the brake circuit. (Note4) : CL output : The "current limit warning (CL) operation circuit outputs warning signal whenever the arm current exceeds this limit. The circuit is reset automatically by the next input signal and thus, it operates on a pulse-by-pulse scheme. (Note5) : The short circuit protection works instantaneously when a high short circuit current flows through an internal IGBT rising up momentarily. The protection function is, thus meant primarily to protect the ASIPM against short circuit distraction. Therefore, this function is not recommended to be used for any system load current regulation or any over load control as this might, cause a failure due to excessive temperature rise. Instead, the analogue current output feature or the over load warning feature (CL) should be appropriately used for such current regulation or over load control operation. In other words, the PWM signals to the ASIPM should be shut down, in principle, and not to be restarted before the junction temperature would recover to normal, as soon as a fault is feed back from its F O1 pin of the ASIPM indicating a short circuit situation.

By this interlocking, both upper and lower IGBTs of this mal-triggered phase are cut off, and “FO” signal is outputted. After an “input interlock” operation the circuit is latched. The “FO” is reset by the high-to-low going edge of either an upper-leg, or a lower-leg input, whichever comes in later.
