LV8414CS

LV8414CS Bi-CMOS LSI Quad H-Bridge Micro Step Motor Driver with I2C Interface www.onsemi.com Overview The LV8414CS is a motor driver that is available for the PWM constant-current control micro step drive of dual stepper motor. Miniaturization using the wafer level package (WLP) makes the IC ideally suited for driving the stepping motors used to control the lenses in digital still cameras, cell phone camera modules and other such devices. . Feature  Built-in 256-division micro step drive circuit for dual stepper motor  Excitation step proceeds only by step signal input  Peak excitation current switchable to one of 16 levels  Serial data control using I2C interface  Built-in thermal protection circuit  Low supply voltage protection circuit incorporated  On-chip photo sensor drive transistors  On-chip Schmitt buffer Typical Applications  Tablet  Digital Still Camera  Feature Phone  Smartphone WLP32K (2.47×2.47) Specifications Absolute Maximum Ratings at Ta = 25C Parameter Symbol Conditions Maximum supply voltage 1 Maximum supply voltage 2 Output peak current VM max VCC max IOpeak ch1 to 4 t  10ms, ON-duty  20% Continuous output current 1 Continuous output current 2 Allowable power dissipation IO max1 IO max2 Pd max ch1 to 4 PI *Mounted on a specified board.
