LV8968BBUWR2G: Multi-purpose Three-Phase BLDC Predriver, Developed in Compliance with ISO 26262

The LV8968BB is a multi-purpose three-phase BLDC predriver for automotive applications and developed in compliance with ISO 26262.  This 3−phase peripheral predriver offers integrated BEMF (Back ElectroMotive Force) sensing and 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 the 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 applications with functional safety (FuSa) requirements. 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 predriver for a wide range of ISO 26262 related actuators, fans and pumps.
