Are the L9963E and L9963 battery control and balancing chips compatible with LiFePO4 batteries?

Hello,

According to the datasheets for the L9963E and L9963, the country may be both “a Li-ion battery tracking and protecting chip.” There isn’t any specific point out that they might not paint with LiFePO4 batteries and it is doubtful if ST includes LiFePO4 batteries under “Li-ion” batteries. Want to verify if LiFePO4 may be used with those chips.

Thank You

    Welcome, to the community! L9963 is formerly on NRND (Not Recommended for New Designs), new designs should use L9963E rather.LiFePO4 has a minimal discharge voltage of 2.0 V, a typical cell voltage of 3.2-3.3 V, and a maximum charge voltage of 3.60-3.65. L9963E covers a voltage range between 0.5-4.6Read more

    L9963 is formerly on NRND (Not Recommended for New Designs), new designs should use L9963E rather.
    LiFePO4 has a minimal discharge voltage of 2.0 V, a typical cell voltage of 3.2-3.3 V, and a maximum charge voltage of 3.60-3.65. L9963E covers a voltage range between 0.5-4.6 V per cell, which thus includes LiFePO4, but should also be designed for it by the software of the advanced- position controller.

    Does it answer your question?
    Regards

Hello

I’m developing an operation that does led control with a button, I use a counter for this, but every time I hold the button, the counter increases further than 1 So indeed if I hold the button down, I want it to increase once.

    Perhaps you should debounce the button, as mechanical buttons bounce, i.e. may produce more than one pulse per button press. There are several techniques to do that, one of the easiest is to connect some small capacitor in parallel to the button, which together with the pull resistor forms some lowRead more

    Perhaps you should debounce the button, as mechanical buttons bounce, i.e. may produce more than one pulse per button press.

    There are several techniques to do that, one of the easiest is to connect some small capacitor in parallel to the button, which together with the pull resistor forms some low pass filter. The time constant of that filter should be slightly lower than the period of the maximum speed to press that button(e.g.100.200 ms). You’ll find this solution also at the NUCLEO or DISCOVERY boards.
