Sine wave PWM Drive, Pre driver IC
Overview
The LV8138V is a PWM system pre driver IC designed for three-phase brushless motors.
This IC reduces motor driving noise by using a high-efficiency, sine wave PWM drive type.
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.
Features
• Three-phase bipolar drive
• Sine wave PWM drive
• Drive phase setting function (Set 0-58 degrees 32 steps: There is an adjustment function corresponding to the CTL pin
input)
• 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
• 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-degree electrical angle/1 pulse and 3 pulses)
