The L99MD01XPTR is an octal half-bridge driver for automotive applications.
The L99MD01XPTR device is used to drive DC and/or stepper motors. Four stepper motors can be driven simultaneously using the boost converter. Without the boost converter, the system can run 3 stepper motors in sequential mode or 2 stepper motors simultaneously. The octal half-bridge configuration can also drive 4 DC motors simultaneously or 7 DC motors sequentially.
An integrated 24-bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open load, overcurrent, temperature warning, and overtemperature.
