• Boosted voltage output
• Connections for the two diodes used by
• Ground
• Output current detection
An RF resistor inserted between this pin
and V
voltage used for output current detection.
The current limiter circuit operates by
detecting the voltage on this pin.
• Boost function switching circuit outputs 1
• W-phase output
• V-phase output
• U-phase output
• Supply voltage
Used as the output transistor pre-driver
power supply. This boosted voltage is
used when a low saturation output is
provided. In all other cases this pin will
be at the V
the voltage boost function.
This pin and pin 34 must all be
connected to the frame ground.
This voltage must be stabilized so that
ripple and noise do not enter the IC.
