June 21, 2016 - ON Semiconductor (Nasdaq: ON) introduced the LV8907UW to further expand its lineup of motor controllers. This high-performance, feature-rich device supports an operating range of voltages from 5.5 V to 20 V (4.5 V to 40 V transient) for a compact solution for driving three-phase brushless motors. The LV8907UW integrates a gate driver to drive six N-channel MOSFETs and a two-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 because key parameters and functions such as startup and speed settings can be configured via the SPI interface and stored in embedded non-volatile (OTP) memory. The device also offers open loop and closed loop speed control. For more complex applications, the LV8907UW also supports small microcontroller integrated linear regulators (3.3 V or 5 V, 50 mA), local interconnect network (LIN) transceivers for automotive interworking, and supports a gatekeeper Dog timer.
The LV8907UW is AEC-Q100 compliant and operates over a temperature range of 175 °C to ensure reliable operation in challenging automotive environments. Integrated protection mechanisms include overcurrent, overvoltage, short circuit, undervoltage and overtemperature. The device's features make it ideal for automotive water pumps, oil pumps, fuel pumps, heating and ventilation air conditioning (HVAC) systems, cooling fans and headlamp cooling units.
Ikuya Kawasaki, General Manager of System Solutions at ON Semiconductor, said: "Under market pressures and increasingly stringent legislative measures, automakers must find ways to improve fuel economy. The electronicization of previous mechanical applications was a key step, such as pumps and The LV8907UW's high level of integration and support for sensorless operation allow the motor system to achieve maximum energy efficiency without the need for a microcontroller. The resulting design reduces complexity and bill of materials and enhances reliability."
Packaging and pricing
The LV8907UW is available in an SQFP48K package. The unit price is $5.55 per 2,500 pieces.
