5. Channel 4 Driver (Spindle Motor Driver)
The channel 4 driver is composed of input amplifer with input selection switch, V-I converter and output power amplifiers.
The voltage, V
REF
, is the external reference voltage given by the bias voltage of the pin 26 in Figure. 4.
The input signal, VIN, through the CH4IN (pin24) is amplified by 100K/100K times and then fed to the next amplifier. And
the amplified voltage is amplified by R2/R1 times and then the fed to the level shift circuit.
Level shifit produces the current due to the difference between the input signal and the internal power reference (PVCC/2).
The current produced as +
I and -
I is fed into the driver buffer.
If it is desired to change the gain, then the CH4CAPA (pin25) can be used. It is controlld by the SW (pin3) input signal.
When the SW (pin3) is high level, then the input voltage,VIN, applied to the CH4CAPA (pin25).
