The LV8136V is a PWM system predriver IC designed for three-phase brushless motors. This IC reduces motor driving noise by using a high-efficiency, quiet PWM drive (150-degree drive system). It incorporates a full complement of protection circuits and, by combining it with a hybrid IC in the STK611 or STK5C4 series, the number of components used can be reduced and a high level of reliability can be achieved. Furthermore, its power-saving mode enables the power consumption in the standby mode to be reduced to zero. This IC is optimally suited for driving various large-size motors such as those used in air conditioners and hot-water heaters.

• Quiet PWM drive (150° current-carrying)
• Supports drive phase control (15° lead angle for 150° current-carrying drive. From this state, a lead angle from 0 to 28° can be set in 16 steps)
• Supports power saving mode(power saving mode at CTL pin voltage of 1.0V (typ) or less; ICC = 0mA, HB pin turned
• off)
• Supports bootstrap (maximum duty limit)
• Automatic recovery type constraint protection circuit
• Forward/reverse switching circuit, Hall bias pin
• Current limiter circuit, low-voltage protection circuit, and thermal shutdown protection circuit
• FG1 and FG3 output (360° electrical angle / 1 pulse and 3 pulses)
• Three-phase bipolar drive
