Product overview
Description
The EVAL-L9907 is designed to provide the user with a platform for the evaluation of the L9907 device. The Board provides all the main input/output capabilities necessary to drive a BLCD motor and provide also diagnostic functionalities. L9907 is fully integrated 3-phase pre-driver with integrated booster capable to drive all kind of Power MOS transistors in 3-phase BLDC motor applications up to 54 V. The integrated boost regulator provides sufficient gate charge to driver Power MOS down to 6 V. The circuit is suitable to operate in environments with high supply voltage such as double battery in 48V systems.L9907 is able to control independently the six pre-driver channels to implement all kind of electric motor control strategies, with the possibility to select among 4 gate output current levels while the application is running. All output channels are protected against short circuit.L9907 is equipped with 2 current sense amplifiers. The gain and output offset voltage of each current sense amplifier can be configured by SPI to allow max flexibility for phase or ground current sense strategy. L9907 is protected against over-temperature and shoot through events.The EVAL-L9907 can be plugged directly to SPC560P-DISP Discovery+ board and using the L9907 demonstration software it is possible to implement a 3 Phase Brush-less Motors control.
