CG208 | Two-channel magnetive valve current regulator for automatic transmission control

CG208 | Two-channel magnetic valve current regulator for automatic transmission control

Hydraulic valve driver
Built-in precision
High accuracy over temperature and lifetime

CG208 permits fast and precise control on two hydraulic valves to enable quick and smooth gear shifting.

CG208 simplifies the design of transmission control units. Hardware control loops for each valve significantly reduce the need for high microcontroller calculation power.

Benefits

Integrated low-side drivers and shunts

Hardware solution, no μC necessary for regulation

Higher channel count in combination with an additional CG208 (two channels) or CG240 (six channels)
