LV8907UW - Sensorless Three-Phase Motor Controller
Sensorless Three-Phase Motor Controller for Automotive

PHOENIX, Ariz – June 20, 2016 – ON Semiconductor (Nasdaq: ON ), has further expanded its portfolio of motor controllers with the introduction of the LV8907UW. Supporting an operating voltage range from 5.5 to 20 volts (4.5 to 40 V transient), this high performance and feature-packed device enables streamlined solutions for driving three-phase brushless motors. The LV8907UW integrates gate drivers for six N-channel MOSFETs, and a dual-stage charge pump for 100% duty-cycle operation. In its lowest cost configuration the IC can operate without an external microcontroller. The device requires no programming, as key parameters and functions - such as startup and speed setting - can be configured via SPI interface and stored in embedded non-volatile (OTP) memory. Open-loop and closed-loop speed control are possible. For more complex applications the LV8907UW can also support a small microcontroller with its integrated linear regulator (3.3V or 5V, 50mA), a local interconnect network (LIN) transceiver for automotive connectivity, and a watchdog timer.
