The AtmelВ® ATA6838C is a fully protected hex half-bridge driver designed in Smart Power SOI technology, used to control
up to six different loads by a microcontroller in automotive and industrial applications.
Each of the six high-side and six low-side drivers is capable of driving currents up to 950mA. The drivers are internally
connected to form six half-bridges and can be controlled separately from a standard serial data interface. Therefore, all kinds …
