... APPLICATION NOTES MSK 1695 PIN DESCRIPTIONS the power connection from the hybrid to the bus. The external wiring to the pin should be sized according to the RMS current required by the motor. This pin should be bypassed by a high quality mono- lithic ceramic capacitor for high frequencies and enough bulk capacitance to keep the V+ power supply from drooping ...

... LOW POWER STARTUP When starting up a system utilizing the MSK 1695 for the first time, there are a few things to keep in mind. First, because of the small size of the module, short circuiting the output phases either to ground or the DC bus will destroy the bridge. The current limiting and control only works for current actually flowing through the bridge ...
