ATA6838C

In Production

A fully protected hex half-bridge driver controlling up to six different loads by microcontroller in automotive and industrial applications. It is designed in smart power SOI technology. 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 to combine loads from bulbs, resistors, capacitors, and inductors. The IC supports the application of H-bridges to drive DC motors.
