An increasing number of medium to high-power DC motors are needed in many automotive, portable, and industrial applications. These varied applications benefit from the highest level of design flexibility offered with a product like the L99H01 which drives scalable n-channel MOSFETs in an H-bridge configuration. The L99H01 is the successor of the well established L9903 and L9904 H-Bridge drivers and offers new features like SPI communication as well as new diagnosis and protection features. The integrated high-efficiency gate drivers provide full-gate driving capability for standard or logic-level power MOSFETs to full RDS(ON) even with a battery voltage down to 6 V, which makes it applicable for new requirements within the hybrid and electric vehicle start-stop applications. The integrated standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information. A gain programmable current sense amplifier which can be trimmed for offset is integrated. The two multiplexed floating current-sense inputs allow the user to place current sense resistors in the source path of the low-side power MOSFET as well as in the motor path. Current measurement inside the drain supply line of the high-side path is also possible. PC board temperature measurement of the MOSFET cluster is also possible via thermal sensors because the L99H01 offers an analog input with programmable threshold. Power dissipation can be significantly reduced with the use of programmable active freewheeling, which allows MOSFETs to turn on in parallel with their body diode during a freewheeling event. The L99H01 can also control reverse-battery or reverse polarity protection with a charge pump output that will control an external N-channel MOSFET placed in the supply line between the DC power source and the L99H01 power input pin.
