Supply voltage range from 12V to 72V,  
The E523。52 is a programmable, high-voltage brushless mo-  
tor controller for 24V..48V automotive applications, indus-  
trial 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.  
operational down to 7V  
11V, 100mA high efficiency DC-DC converter for  
gate supply and other loads  
Three complementary 200mA gate drivers with  
programmable dead time and protection features  
Integrated automotive 16Bit RISC processor with  
4k SRAM and hardware MAC and divider units  
32kByte Flash with ECC error protection  
Self advancing half bridge PWM generators auto-nomously  
generate various commutation waveforms  
1MS/s 12bit ADC autonomous sample sequence engine  
synchronized to PWM with direct memory access  
One SPI module

Up to 9 configurable IO pins facilitate interfacing with the ap-  
plication and the outside world. All IOs can be sampled by a  
12bit, 1MS/s ADC with direct memory access。  
ƒ
Three self advancing PWM generators with integrated dead  
time can implement various wave-forms。 Fully integrated  
back-EMF channels allow sensor-less commutation. Auto-  
matic ADC triggering allows programming of complex com-  
mutation algorithms. The memory can be divided into pro-  
tected and field programmable areas.

4 timer capture and compare units with QEI modes  
One high voltage enable, 9 general purpose IOs  
Thermally efficient 7x7mm 36pin QFN package  
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.
