MC44605 Pin 1 V CC This pin is the positive supply of the IC.
Pin 2 V C The output high state, V OH, is set by the voltage applied to this pin. With a
separate connection to the power source, it gives the possibility to set by means of an
external resistor the output source current at a different value than the sink current.
Pin 3 Output The output current capability is suited for driving a power MOSFET.
Pin 4 GND The ground pin is a single return typically connected back to the power source.
It is used as control and power ground.
Pin 5 Maximum Power Limitation This block enables to estimate the input power. When
this calculated power is detected as too high, fault information is sent to the disabling block
in order to definitively disable the circuit.
