Product overview
概要
The L99MD01 is an octal half-bridge driver for automotive applications.
The device is intended to drive DC and/or stepper motors. Using the boost converter it’s possible to drive 4 stepper motors simultaneously. Without boost converter the system is able to run 3 stepper motors in sequential mode or 2 stepper motors simultaneously. The octal half bridge configuration allows also to drive 4 DC-motors simultaneously and 7 DC-motors sequentially.
The integrated 24 bit standard Serial Peripheral Interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in on-state, overcurrent, temperature warning and overtemperature.
