LV8414CS

www.DataSheet.co.kr Ordering number : ENA1868 LV8414CS Overview Bi-CMOS IC Microstep Driver Motor Driver IC The LV8414CS is a motor driver IC that incorporates two channels of PWM constant-current control micro-step drivers. 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. Features Two channels of 256-division micro-step drivers 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 Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage 1 Maximum supply voltage 2 Output peak current Continuous output current 1 Continuous output current 2 Allowable power dissipation Operating temperature Storage temperature Symbol VM max VCC max IOpeak IO max1 IO max2 Pd max Topr Tstg ch1 to 4 t ≤ 10ms, ON-duty ≤ 20% ch1 to 4 PI *Mounted on a specified board. 400 30 1.0 -30 to +85 -55 to +150 mA mA W °C °C Conditions Ratings 6.0 6.0 600 Unit V V mA * Specified circuit board : 40mm×50mm×0.8mm, glass epoxy four-layer board.
