The VNH7013 was designed with this device in mind. The L99H01 is an H-Bridge controller designed to drive four MOSFETs in an H-Bridge configuration. Specifically, it drives the VNH7013 very neatly. The block diagram, shown here, illustrates the VNH7013 with the L99H01. The L99H01 has a pin designed to measure the diode string in the VNH7013. If the voltage drops below a programmed threshold the L99H01 can turn off the bridge. The L99H01 as two current sense amplifier inputs. So designers can put a resistor either on one of the motor legs, on the ground, or even on the supply. These two devices were designed for each other. The L99H01 was designed in the QFP32 and the PSSO36 packages depending if there is a need for added thermal conductivity. There are very few components required between them. It will require some gate resistors as this part does not have a programmable gate drive. As a result engineers will need gate resisters to manage the slew rate to where it is needed. The operating voltage upper limit for this device is 28V. This may limit some industrial applications.
