LB1941GP Datasheet | SANYO

Ordering number : ENA0610 .. Monolithic Linear IC Overview For Digital Cameras Constant Current Forward/Reverse Driver 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 m A 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 Maximum supply voltage Output current Output applied voltage Input applied voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max IO max VO max VIN max Pd max Topr Tstg IN1, IN2 Mounted on a specified board.- Conditions Ratings -0.3 to +10.5 600 -0.3 to VCC+0.3 -0.3 to +10.5 0.7 -20 to +75 -55 to +150 Unit V m A V V W °C °C Note- : Mounted on a board: 50×40×10.8 mm3: glass epoxy four-layer.
