ON Semiconductor Announces Sensorless Three-Phase Motor Controller for Automotive BLDC Implementation

Highly integrated solution, including BLDC commutation and gate drivers, eliminates need for microcontroller unit

PHOENIX — (BUSINESS WIRE) — 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 nonvolatile (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.

AEC-Q100 qualified, the LV8907UW’s operational temperature range reaches up to 175 °C, thereby ensuring reliable operation in challenging automotive environments. Integrated protection mechanisms include over-current, over-voltage, short circuit, under-voltage, and over-temperature. The features of the device make it ideal for use in automotive water pumps, oil pumps, fuel pumps, HVAC systems, radiator fans, and headlamp cooling units.

“Compelled by market pressures and increasingly stringent legislative measures, automotive manufacturers need to find ways to improve the fuel economy of their models. Electrification of former mechanical applications – such as pumps and fans – is a key step in this path,” explains Ikuya Kawasaki, General Manager of System Solutions Group at ON Semiconductor. “Thanks to its high degree of integration and support for sensorless operation, the LV8907UW enables motor systems to attain maximum efficiency levels without a microcontroller. The resulting designs have reduced complexity and bill of materials, and enhanced reliability.”

Packaging and Pricing

The LV8907UW is supplied in a SQFP48K package format. It is priced at $5.55 per unit in 2,500 unit quantities.
