1 / 4 page 60607 MS IM / N2502 AS (OT) No.7193-1/4 LB1941T Overview The LB1941T is a single-channel forward/reverse driver IC that provides a constant current control function. Its low-saturation output makes it appropriate for voice coil motor control, and it is optimal for use as the shutter driver IC in digital cameras. Functions • Constant current control (IO = 400mA when Rf = 0.5Ω) • Ultraminiature package (MSOP8: 150mil) • Built-in thermal protection circuit • Includes a rapid charge/rapid discharge circuit for stable shutter operation. • Built-in reference voltage circuit (0.2V typical) Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max -0.3 to +10.5 V Output current IO max 600 mA Output applied voltage VO max -0.3 to VCC+0.3 V Input applied voltage VIN max IN1, IN2 -0.3 to +10.5 V Allowable power dissipation Pd max Mounted on a specified board.* 400 mW Operating temperature Topr -20 to +75 °C Storage temperature Tstg -55 to +150 °C Note*: Mounted on a board: 114.3mm ×76.1mm×1.6mm, glass epoxy resin.
