CST2466/CT2466E概述:
CST2466/CST2466E是2.1A H桥驱动芯片。较宽的输入电压2至11V。超低内阻280mΩ,CST2466/CST2466E提供SOP8和ESOP8两种封装。
CST2466/CST2466E为电动牙刷、摄像机、消费品、玩具和其他低电压或电池驱动的应用提供了集成电机驱动器控制, CST2466/CST2466E可提供高达2.1A的直流输出电流,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。CST2466/CST2466E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。CST2466/CST2466E提供SOP8和ESOP8两种封。
The CST2466/CST2466E provides an integrated motor driver for cameras, consumer products, toys and other application with low-voltage or battery-powered motion control.The CST2466/CST2466E can supply up to 2.1A 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 CST2466/CST2466E has a PWM (INA、INB) input interface. Full protections are integrated with over-current protection, under-voltage lockout and over-temperature shutdown.

CST2466/CST2466E PCB布局指导及典型应用电路图

  
  The capacitor C1 connected between the GND and the VM pins must be located as close as possible to the CST2466/CST2466E 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 CST2466/CST2466E, it need to place a small capacitor for CST2466/CST2466E.
  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 .
