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.
FEATURES
* VDD range: PVDD 8V to 30V
* each channel current limit: 50mA
* Integrated internal 6V regulator
* Maximum clock frequency: 0.5MHz
* Built-in open/short detection
* Short protect
* Detecting response
* Internal reverse diode of PVDD to Absorb reverse current from coil
