LV8968BBUWR2G

The ON Semiconductor LV8968BBUWR2G is a versatile three-phase Brushless DC (BLDC) predriver engineered for automotive applications, compliant with ISO 26262 standards. This device supports a wide operating voltage range, from 8 V to 28 V for full drive power, with transient tolerance up to 40 V. It also features an extended voltage range from 6 V to 33 V when using logic level mode.

Key features include six gate drivers capable of providing 400 mA typical gate current, enabling the use of low-resistance power FETs. The device incorporates extensive system protection, including drain-source short detection, overcurrent shutoff, low gate voltage warning, overtemperature warning and shutoff, and over/undervoltage protection. It supports motor PWM frequencies up to 30 kHz and offers an SPI interface for real-time parameter setup and diagnostics.

The LV8968BBUWR2G is housed in a 48-pin SQFP package with an exposed pad, designed for thermal efficiency and transient operation up to 175°C. It includes a programmable linear regulator providing 5 V or 3.3 V for external loads up to 50 mA, and an integrated window watchdog timer for microcontroller support. Critical system parameters can be programmed into nonvolatile OTP memory.

This predriver is AEC-Q100 qualified and PPAP capable, making it suitable for demanding automotive environments. Applications include suspension systems, park brakes, transmissions, steering pumps, vacuum pumps, battery pack cooling, sliding doors, and lift gates.
