U8C3525 Datasheet






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




*VDD range: VDD  5V to18V

           PVDD 5V to 35V

*Maximum clock frequency: 1MHz

*current limit of Each channel:250mA

*Built-in open/short detection  

*Short protect

*Detecting response

*Internal reverse diode of PVDD to Absorb reverse current from coil
