Elmos Brushless DC Motor Controller Integrates 16-Bit CPU to Improve System Performance

[Elmos Brushless DC Motor Controller Integrates 16-Bit CPU to Improve System Performance] According to foreign media reports, Elmos's E523.06 is a system chip for brushless DC motors, gate driver from 12V automotive electronics system (gate driver) , gatedriver) is composed of a 16-bit CPU chip that can control up to 3 channels of metal oxide semiconductor (NMOS) half bridges, DC motors or other loads. The CPU architecture and motor peripheral drivers (motordriverperipherals) are optimized for the application of the SingleOriented Field Oriented Control (FieldOrientedControl) process.

The integrated circuit calculates the motor position and commutation time. There is no need to add Hallsensors. The shunt becomes the only measuring component used for external current. The current contained in this module effectively prevents overload current (sustainable adjustment of its threshold), over temperature, over voltage, under voltage, and short circuit (programmable threshold values are set for each field effect transistor).

In addition to the cost-effective design of the target application, the integrated circuit also supports the use of debug interface (JTAG) or high-speed LIN for end-of-line programming. It may also include the following applications: cooling fans, air conditioning fans and fuel pumps, hydraulic pumps, oil pumps or pumps.

The 16-bit CPU is connected to the coprocessor and can be used to perform ADC tasks. Pulse width modulation (PWM) generation ensures high system performance. With this hardware acceleration, the processing speed of the closed control loop is extremely fast, and the operation of the entire motor module can be completed in one PWM cycle. This high-bandwidth integrated circuit measurement amplifier also handles current values. All features can be used to optimize system performance, system stability, system reliability, power consumption, and program debug time.
