U8C3525

DESCRIPTION 

The U8C3525 is an 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 250mA by 

Built-in constant current source. 

The U8C3525 has two power supplies, VDD provides power to 

Internal control and communication modules. The range of VDD is 

5V to 18V. PVDD is used to absorb the inductive coil 

reverse-phase current and the range of PVDD is 5V to 35V. 

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.
