1 / 4 page 60607 MS IM / N2502 AS (OT) No.7193-1/4 http://onsemi.com Semiconductor Components Industries, LLC, 2013 June, 2013 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. Monolithic Linear IC For Digital Cameras Constant Current Forward/Reverse Driver IC Ordering number : EN7193B Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. |
