General Description
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 mo-
tor a dynamically programmable, precise dead time gen-
eration and a current amplifier are implemented. Diag-
nostic functions are detecting over current (dynamically
programmable threshold), over-temperature, over-/ un-
der-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 trans-
ceiver or with a PWM-interface are available. The LIN in-
terface supports “FLASH Mode” to upload a new firm-
ware. 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.
