 DESCRIPTION

The U8C3005 is a 8-Bit Serial-In Parallel-Out driver with Error

Detection to the solenoid valve drive. The device incorporates shift

registers, data latches, and constant current circuitry on the silicon

CMOS chip. The maximum output current value of one channel is

Approximately limited to 50-85mA by Built-in constant current

source.

The range of power supply PVDD is 8V to 30V and the

Integrated internal 6V Regulator is used for low-voltage power

supply module communication. Moreover, PVDD can be also used

to absorb the inductive coil reverse-phase current with a built-in

reverse diode Between the output of each channel and PVDD in the

time of turn off.

Its built-in open/short detection circuits help users detect Load

state of the detection channels. System retrieve the error

messages to indicate which channel has failure by serial output

data.
