FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
CCD2 CONSTANT CURRENT CONTROLLER
The CCD2 constant current controller is a switching
hysteretic current controller with a superimposed dither. The
controller is designed to provide a programmable constant
current through a solenoid valve. By controlling current
through the solenoid valve, fluid flow control is achieved.
The master SPI device sends 16-bit command words to
the 33800 device (see
Table 18
). The master device sets up
the output current based on the CCD2 Control command.
The IC is capable of sinking an average output current from
0.0mA to 232mA (without dither). If operating the device with
dither, the DAC + Dither value must be less than 232mA or

Trim Set bit indicates (0=untrimmed, 1= trimmed)
VCAL Status bit indicates when internal or external supply is used. VCAL Bit = 0 indicates external, VCAL Bit = 1indicates internal.
Reset Bit indicates the device has performed a POR.
CCD1 DISable bit allows the CCD1 driver to operate as a standard 1.0A low side driver. With CCD1_DIS bit = 1 the CCD1 function is
disabled.
