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.
