1 / 4 page Ordering number : ENA0610A Monolithic Linear IC For Digital Cameras Constant Current Forward/Reverse Driver LB1941GP Overview The LB1941GP 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 • High-performance dual operational amplifier • Constant current control (IO = 400 mA when Rf = 0.5Ω) • Built-in thermal protection circuit • Includes a rapid charge/rapid discharge circuit for stable shutter operation. • Built-in reference voltage circuit (0.2 V typical) • Ultraminiature package (VCT16 (2.6mm × 2.6mm) Specifications 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.* 0.7 W Operating temperature Topr -20 to +75 °C Storage temperature Tstg -55 to +150 °C Note*: Mounted on a board: 50 ×40×10.8 mm3: glass epoxy four-layer. Allowable Operating Range at Ta = 25°C Parameter Symbol Conditions Ratings Unit Function-guaranteed voltage range VOPR 2.5 to 10 V Constant-current set range IOUT Set with RFG-GND resistance 50 to 500 mA Input low level voltage VIL IN1, IN2 -0.3 to +0.5 V Input high level voltage VIH IN1, IN2 2.0 to 10 V ■ Any and all SANYO Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
