CY335

6-channel injector driver for direct injection engines

Application & Technical Summary

CY335

CY335 controls up to six injectors. The two-bank concept permits two independent injections at a time. High flexibility is guaranteed due to multiple configuration and programming options.

The use of external power components (switches and shunts) provides a high degree of freedom to the control unit designer. A CY335-based system can be adapted to any direct injection valve in the market.
