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 sensorless commutation. Automatic ADC triggering allows programming of complex commutation algorithms. The memory can be divided into pro-tected 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 +150°C.
