This IC controls up to 3 NMOS half bridges for driving BLDC motors or other loads. It’s also possible to drive loads directly at battery supply. For controlling the motor a dynamically programmable, precise dead time generation and a current amplifier are implemented. Diagnostic functions are detecting over current (dynamically programmable threshold), over-temperature, over-/ under-voltage and short-cuts, one for every FET (HS and LS with different dynamically programmable threshold).
Product versions with a “state of the art” LIN2.x transceiver or with a PWM-interface are available. The LIN interface supports “FLASH Mode” to upload a new firmware. The LIN UART is compatible to LIN2.1. The IC provides an integrated 16 bit RISC CPU, assited by hardware waveform generation. Development tools are available. Motor commutation can be done with hall-sensors or other sensor-less principles.
