 Making DC-motor driving simple and safe
In order to meet upcoming regulations on CO2 emission reductions, an increasing number of high-power DC motors are
needed in many automotive applications. These require flexible and scalable MOSFET drivers in H-bridge configuration,
which are able to cover a wide range of applications from powertrain and safety to comfort and convenience.
The L99H01 is a new device from STMicroelectronics, and is the successor of the well established L9903 and
L9904. The circuit offers SPI communication as well as comprehensive diagnosis and protection features. High-
efficiency gate drivers provide
