    CST2466A/CST2466AE概述
    CST2466A为摄像机、消费品、玩具和其他低电压或电池驱动的应用提供集成电机驱动器控制。CST2466AE可提供高达1.8A的直流输出电流。它使用2-11V的电机电源(VM)和2V-6V的设备电源(VCC),超低的RDS-on允许SOP-8包可用。CST2466A具有PWM(INA、INB)输入接口。全套保护与过流保护、欠压闭锁和超温停机相结合。峰值电流3.5A,CST2466A提供SOP-8和ESOP-8封装。
    The CST2466A provides an integrated motor driver for cameras, consumer products, toys and other application with low-voltage or battery-powered motion control.The CST2466AE can supply up to 1.8A of output DC current. It operates on a motor power supply (VM) from 2 to 11V and a device power supply voltage (VCC) of 2V to 6V. Ultra- low RDS-ON allows SOP-8 package available. The CST2466A has a PWM (INA、INB) input interface. Full protections are integrated with over-current protection, under-voltage lockout and over-temperature shutdown.

    CST2466A/CST2466AE PCB布局指南:

        The capacitor C1 connected between the GND and the VM pins must be located as close as possible to the CST2466A chip. In different applications, C1(show as above) is recommended to use a 0.1uF in 3V applications; a 1uF is recommended for 4.5V applications; a 4.7uF is recommended for 6V applications; in 9.6V applications, it is recommended to use 22uF, all these capacitors should be SMD package.The connection between the negative pole of the capacitor and the GND terminal of the IC should be as short as possible.  That is to say, the line route should not far away. 
        When the application board has capacitors while filtering for other chips that is far away from the CST2466A, it need to place a small capacitor for CST2466A.
    The capacitor C3 preferably soldering to the motor poles instead of placing it on the PCB. When it is inconvenient to soldering on the motor poles,  it can be mount on the PCB.  The following diagram is the PCB layout reference .
