Ordering number : ENA0288 Bi-CMOS IC LV8227LG For MD and UMD System Motor Driver IC Overview The LV8227LG is a system motor driver IC that implements all the motor driver circuits needed for MD and UMD (Universal Media Disk) products. The LV8227LG provides a three-phase PWM spindle driver, a sled driver (as two three-phase stepping motor driver channels), and focus and tracking drivers (as two PWM H bridge driver channels). Since the LV8227LG uses Bi-CMOS process, it can contribute to further miniaturization, thinner from factors, and lower power in end products. Functions • PWM H bridge motor drivers (2 channels) • Three-phase stepping motor driver (2 channels) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Supply voltage range 1 VCC max 6.5 V Supply voltage range 2 VG max 15.0 V Output block supply voltage VM max 6.5 V H-bridge channel 1 and 2 output current IO max1 0.3 A Three-phase half-bridge channel 1 output current Three-phase half-bridge channel 2 output current IO max2 0.3 A IO max3 0.6 A Allowable power dissipation 1 Pd max1 Independent IC 0.3 W Allowable power dissipation 2 Pd max2 Mounted on the specified board * 1.45 W Operating temperature Topr -20 to +85 °C Storage temperature Tstg -55 to +150 °C The specified board *: 50×40×0.8mm3 4-layer glass-epoxy circuit board.
