Hello, What should be the voltage across VBAT and VBAT- of the M4Z32- BR00SH1 battery at the moment of purchase? However, can it be recharged? If it’s zero at the time of purchase. Thank You

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.

We want to develop a USB- C charger and we need to check the battery charge percentage of the device connected to the USB- C charger. The connected to de USB- C device can be a Smartphone, Tablet, or PC.
In our charger, we’re going to integrate a processor and we need to read the battery percentage of the device that’s being charged
Is it possible to read the battery percentage of the device connected by USB- C? Any ST reference can do this job?

Hello, Battery_status message can give the SOC of the sink. The info will be available only on the PD3 sink( designed with version> = PD3.0 v1.2). PD2 devices do not have similar communication. That information is handled in the dpm_user part and needs to be updated by the user/ customer. Best reRead more

Welcome, to the community! The voltage between both terminals should be nominally 2.8 V, below 2.0 V it should be considered discharged. The battery is based on lithium carbon monofluoride chemistry and isn't rechargeable. Does it answer your question? Regards Alex
