This pin and pin 34 must all be

connected to the frame ground.

4.2 to 6.5 V

• Supply voltage

This voltage must be stabilized so that

ripple and noise do not enter the IC.

VCC + 1.55 Vtyp

(Ip = –5 mA)

• Boosted voltage output

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 VCC potential.

• Output current detection

An RF resistor inserted between this pin

and VCC converts the output current to the

voltage used for output current detection.

The current limiter circuit operates by

detecting the voltage on this pin.
