LV8968BBUWR2G中文资料Multipurpose Three-Phase Brushless DC Predriver, Developed in Compliance with ISO 26262数据手册ONSEMI规格书

描述 Description

The LV8968BB is a 3−phase BLDC/PMSM pre−driver with integrated BEMF (Back ElectroMotive Force) sensing and logic level FET compatibility. The wide operating voltage range and AEC−Q100 qualification make this device ideal for automotive applications. Six gate drivers provide 400 mA (typ) gate current to external power
bridges allowing use of low−resistance power FETs as well as logic level FETs. All FETs are protected against overcurrent, short−circuit, over−temperature and gate undervoltage. A multitude of protection and monitoring features make this device suitable for ISO26262 applications. Three independent low−side source pins allow multiple shunt measurement.
The device also includes a programmable linear regulator, a fast current−sense amplifier and a window watchdog for microcontroller support. The SPI interface allows for real time parameter setup and diagnostics. Critical system parameters can be programmed into non−volatile OTP memory.
Junction temperature tolerance up to 175°C and control via wide level WAKE and PWM signals make the LV8968BB an ideal motor pre−driver for automotive applications such as engine cooling fans, fuel, oil, and hydraulic pumps.
