LB1619M

The LB1619M is a 3-phase brushless motor driver IC ideally suited for use in VTR capstan motor driver, drum motor driver applications.

The features of LB1619M can be summarized as (1)120° voltage linear type; (2)speed control based on motor voltage control; (3)soft switching type eliminating noises caused by current switching and making the values of external capacitors smaller (comparable to those of chip capacitors); (4)on-chip torque ripple compensation circuit; (5)on-chip thermal shutdown circuit.

The absolute maximum ratings and allowable operating conditions of LB1619M are (1)maximum supply voltage VCCmax: 16V; (2)maximum supply voltage VSmax: VCCV; (3)output current IO: 1.5A; (4)hall supply current IH: 20 mA; (5)allowable power dissipation Pd max: 1.0W; (6)operating temperature Topr: - 20 to 75°C; (7)storage temperature Tstg: - 55 to + 125°C; (8)supply voltage VCC: 6 to 16V(Design Notes) it should be noted that dielectric breakdown is liable to occur between pin 11 and other pins.
