• LTC2946设备通过I2C通信不上

    我使用ARM架构的DSP设备(F28M35X)控制I2C设备,采集电压电流信息,但是始终通信不上。DSP支持400Kbps模式和100Kbps模式,时钟高低电平比Tlow:Thigh=6:4。DSP采用I2C的400Kbps模式时,实际速率374Kbps,周期T=2.67us。实际测量Tlow:Thigh≈6:4=1.58us:1.28us。查看LTC2946设备时序,不知是否支持400Kbps及以下速率进行通讯?我目前DSP的I2C设备接口是否无法满足LTC2946时序要求?

  • Regarding LTC2946 ,permits reverse current

    Hello Sir,

    LTC2946 was connected to battery with VIN and VOUT to load .Current will pass through VIN to VOUT that is fine.

    But while charging current will pass thourgh VOUT to VIN . Can current pass through like that or it will damage the ic ?

  • LTC2946 reverse current measuring

    Hi Sir,

    We are connecting LTC2946 VIN to Battery +ve and VOUT to load. That time current will pass through VIN to VOUT.

    While charging the battery current will pass thourgh VOUT to VIN , Is this operate in reverse current.

    Thanks and regards

  • LTC2946 RSNS Sense Resistor

    I am using the LTC2946 device to measure and monitor the power, charge and energy into and out of a battery.

    To do so I intend to connect the battery output (+ve terminal) to a DC shunt, to produce the sense voltage required for the LTC2946 device.
