1 / 8 page D2006 SY IM B8-8570 No.7896-1/8 LB8652T Features • Actuator driver for digital cameras embedded in one chip. (Not supported synchronous driving.) (1) Saturation output for AF - Stepping motor (2 phase, 1-2 phase excitation possible) (2) Constant current control output for SH • Quick charge and quick discharge circuitry allow the stabilization of response speeds. • Input port 1 allows shutter close control. • When shutter opening control, open-loop constant current control is possible. (3) Saturation output for AE - VCM or stepping motor can be used. (2 phase, 1-2 phase excitation possible) (4) ZOOM (lens barrel) - Constant voltage DC motor driver (Normal evolution/Reverse evolution/Brake) Or saturation output stepping motor (2 phase, 1-2 phase excitation possible) • Applications of various actuators possible. SH AE AF ZOOM Application Example 1 VCM VCM STM DCM Application Example 2 VCM VCM STM STM Application Example 3 VCM STM STM DCM • No standby current consumption (or zero). • 2 system power source (VB : for DC motor, VCC : others) • Low saturation output • Built-in thermal protection circuitry • Small, thin package Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit VB max VB 10.5 Maximum Power Source Voltage VCC max VCC 10.5 V Maximum Applied Input Voltage VIN max MD1 to 3, IN1 to 4 10.5 V Maximum Applied Output Voltage VOUT max OUT1 to 8 10.5 V Continued on next page. Ordering number : EN7896C Monolithic Digital IC Driver for Digital Still Cameras 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. Consult with your SANYO Semiconductor representative nearest you before using any SANYO Semiconductor products described or contained herein in such applications. SANYO Semiconductor assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor products described or contained herein. |
