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 it can operate without an external microcontroller.
The device requires no programming, as key parameters and functions - such as start-up and speed setting - can be configured via SPI interface and stored in embedded non-volatile (OTP) memory. Open-loop and closed-loop speed control is also possible. For more complex applications it can 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.
The controller is AEC-Q100 qualified and has an operational temperature range that reaches 175°C, 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 suitable for automotive water pumps, oil pumps, fuel pumps, HVAC systems, radiator fans, and headlamp cooling units.
