LV8139JA数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

The LV8139JA 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.

特性 Features

• Three-phase bipolar drive
• Sine wave PWM drive
• Drive phase setting function (Set 0-58° 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 0.95V (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)
