Includes BLDC current & gate driver, no additional MCU required

ON Semiconductor has expanded its portfolio of existing motor controllers with the launch of the LV8907UW. Supporting a drive power range of 5.5 to 20 volts (transient voltage of 4.5 to 40 volts), this high-performance and multi-functional device is the latest solution for efficiently operating three-phase brushless motors.

The newly released LV8907UW integrates a two-stage charge pump for 100% duty cycle operation and gate drivers for six N-channel MOSFETs. Boasting a design configuration for the lowest cost, this integrated circuit can operate without an external microcontroller.

This device, which allows key variables and functions such as startup and speed settings to be configured via the SPI interface and stored in built-in non-volatile (OTP) memory, does not require separate programming. Open-loop and closed-loop speed control is also possible.


The LV8907UW also supports a small microcontroller with an integrated linear regulator (3.3V or 5V, 50mA) for more complex and sophisticated applications, a LIN transceiver for automotive connectivity, and a watchdog timer.

The LV8907UW, compliant with AEC-Q100 standards, has a maximum operating temperature of 175°C and enables stable operation even in harsh automotive environments. It also incorporates mechanisms to protect against overcurrent, overvoltage, short circuits, undervoltage, and thermal overload. Due to these features, it is ideally used in automotive water-cooled pumps, oil pumps, fuel pumps, HVAC systems, radiator fans, and headlamp cooling units.

Ikuya Kawasaki, General Manager of ON Semiconductor’s System Solutions Group, explained, “Automakers, facing various market pressures and increasingly stringent legislative measures in each country, are focused on ways to improve the fuel economy of new vehicle models,” adding that the electrification of existing mechanical applications, such as pumps and fans, is an essential element of this solution.

Manager Kawasaki also explained, “The LV8907UW, which boasts a high level of integration and supports sensorless operation, enables motor systems to achieve maximum efficiency without an MCU. As a result, it reduces system complexity and BOM while also enhancing system reliability.”
