3-phase brushless motor pre-driver BD63002MUV General Description Key Specifications BD63002MUV is pre-driver of 3-phase brushless motor. Power supply voltage rating: 30V It generates a driving signal from the Hall sensor and Operating temperature range: -40C to +85C drives PWM through the input control signal. Since there Stand-by current: 1.2mA(Max.) is a built-in booster circuit, Nch-Nch MOS transistors can Range of in-phase input voltage be used on the external power transistor. In addition, the for hall input: V -1.7V(Max.) REG power supply can use 12V or 24V and it has various Current limit detect voltage: 0.2V10% controls and protection functions built-in, making it useful UVLO Lock out voltage: 6.0V(Typ.) for a variety of purposes. Because it adopts small OVLO Lock out voltage 1: 16.0V(Typ.) packages, it can also be used on small diameter motors. OVLO Lock out voltage 2: 28.5V(Typ.) Features Package W(Typ) x D(Typ) x H(Max) Built-in 120 commutation logic circuit. VQFN028V5050 5.00mm x 5.00mm x 1.00mm Driving with Nch-Nch MOS transistors. PWM control mode (low side arm switching). Built-in power-saving circuit. CW/CCW function. Short brake function. FG output (Open drain). Built-in protection circuit for current limiting, overheating, under voltage, over voltage, motor lock. Applications OA machines. Other general civil equipments.
