E523.52
Features
General Description
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.
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.
Applications
48V automotive and commercial vehicle applications
BLDC-Motors in industrial 24V to 72V applications
