Sensorless Three-Phase Brushless DC Motor Controller and Predriver, Automotive

Favorite

Overview

The LV8907 is a high performance, sensorless three-phase BLDC motor controller with predrivers for automotive applications.  An integrated two-stage charge pump provides gate current for a wide range of ultra low RDS(ON) NFETs. The device offers a rich set of system protection and diagnostic functions such as overcurrent, overvoltage, short-circuit, undervoltage, overtemperature and many more. It supports open-loop as well as closed-loop speed control with user configurable startup, speed setting and proportional/integral (PI) control coefficients, making it suitable for a wide range of motor and load combinations. With a built-in linear regulator for powering external circuits, a watchdog timer, and a Local Interconnect Network (LIN) transceiver, the LV8907 offers a very small system solution. The LV8907 stores system parameters in embedded one-time programmable (OTP) non-volatile memory in addition to RAM system memory.  An SPI interface is provided for parameter setting and monitoring the system status. With the operating junction temperature tolerance up to 175°C and electrically LIN compatible control signals (PWM and Enable), the LV8907 is an ideal solution for stand-alone BLDC motor control systems.
