72V Programmable Brushless Motor Controller with 16bit CPU E523.52 PRELIMINARY INFORMATION – Jan 18, 2017 Features Brief functional description Supply voltage range from 12V to 72V, operational The E523.52 is a programmable, high-voltage brushless
motor controller for 24V.48V automotive applications,
industrial applications and commercial vehicles. It integrates 3 half-bridge drivers, a 11V step down converter,
two linear regulators, and a 16bit RISC microcontroller
with 32kB Flash.
The DC-DC converter efficiently provides 11V for the six
gate drivers, the internal linear regulators, and other
loads such as external Hall sensors. Up to 9 configurable IO pins facilitate interfacing with the application and
the outside world. All IOs can be sampled by a 12bit,
1MS/s ADC with direct memory access.
Three self advancing PWM generators with integrated
dead time can implement various wave-forms. Fully
integrated back-EMF channels allow sensor-less commutation. Automatic ADC triggering allows programming
of complex commutation algorithms. The memory can
be divided into protected and field programmable areas.
Internal temperature monitoring and a thermally efficient
36 Pin QFN package enable the driver section to operate close to its maximum junction temperature of 150В°C. down to 7V
