Elmos will present its portfolio of motor drivers and LED controller ICs at the electronica in Munich (13 to 16 November 2018). Elmos has delivered more than 500 million motor drivers to customers, is the world leader for LED ambient lighting, and offers a patented heat distribution solution for the LED rear light. You will find us in the Automotive Hall (Hall B4, Booth 439).
The E523.06 is a BLDC motor system-in-a-chip, consisting of a gate driver for the 12V vehicle electrical system combined with a powerful 16-bit microcontroller. It controls up to 3 NMOS half bridges of BLDC, DC motors or other loads. The CPU architecture and motor driver peripherals are optimized for the single-shunt FOC (Field Oriented Control) method. The IC calculates the motor position and the commutation times without additional hall sensors. The only measuring element in the external wiring is a shunt. In addition to the cost-effective design of the target application, the IC supports end-of-line programming via JTAG or high-speed LIN. In-vehicle updates can be carried out with the bootloader. Possible applications include: radiator fans, air conditioning fans and pumps (fuel, hydraulics, oil or water).
With the E522.90/91/92/93 ICs, Elmos is presenting a product family of LED controllers for use in automotive rear lighting. The E522.9x family has an output current of 14mA to 55mA per channel. Up to 165mA/IC is possible in parallel operation. Patented power management ensures a constant lighting intensity of the LEDs even under difficult thermal conditions. A variable proportion of the incurred power loss is shifted to external shunts for this purpose, enabling even and effective heat distribution without hot spots on the PCB. Here the unique dual concept avoids an additional drop via the linear controller stage. With higher current (48-151mA per channel or 450mA in parallel operation) but otherwise the same unique features, Elmos has been supplying successfully the E522.8x product family for a long time.
The Elmos IC E521.36 enables a simple, variable, cost-efficient and very space-saving design of RGB LED modules for connection to a LIN-BUS. The device includes a MSP430 based 16-bit microcontroller with 32kbyte NVM, 128byte EEPROM, a LIN transceiver (up to LIN 2.2) with integrated BSM auto-addressing (bus shunt method), four current sources with up to 40mA each and three 16-bit PWM generators. The 48MHz PWM clock ensures full 16-bit color resolution at a 732Hz repetition rate, enabling flicker-free applications and meeting all known OEM requirements.
