U8C3005中文资料8 BIT SERIAL-IN PARALLEL-OUT VALVE DRIVER数据手册UTC规格书

描述 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.
