Description

The U6815BM is a fully protected driver interface designed in 0.8-µm BCDMOS technology. It is used to control up to 12 different loads by a microcontroller in automotive and industrial applications.

Each of the 6 high-side and 6 low-side drivers is capable of driving currents up to 600 mA. The drivers are freely configurable and can be controlled separately from a standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitors, and inductors can be combined. The IC design especially supports the applications of H-bridges to drive DC motors.
