With a switching characteristic specially optimized for inductive loads, the CG208 is particularly well-suited for the high-precision control of magnetic valves in hydraulic circuits. Applications for the regulator are consequently enabled in both automobile manufacturing – e.g., hydraulic control of automatic transmissions – and industrial electronics. Samples of the new current regulator are immediately available; series production is expected to start at the beginning of 2007.
This new module is equipped with internal digital control electronics that maintain the selected output current constant under changing environmental conditions. External computing power is therefore not required – a factor that quickly becomes very advantageous with heavily loaded processors used in control electronics.
The CG208's housing includes two identical current regulators, which can, however, be set absolutely independent of one another. Both feature a power switch in the low-side branch of the control circuit (standard in Europe), so that the external connection only requires the minimum amount of components. A shared SPI interface (Serial Peripheral Interface) is provided for programming the operating characteristics with a processor; in the opposite direction, this interface signals the status of chip-internal autodiagnostics back to the processor. Internal overload protection automatically prevents damage caused by short-circuits and excessive temperatures.
