Part Number: TPS43330-Q1 This thread applies to TPS43330-Q1.
In device TPS43330 (non-A version): When device in LPM and waking up EXTSUP gets shorted to VREG and that may cause a restart of the device (including running buck regulators): High-IQ in…
Part Number: TPS65910 This thread applies to TPS65910x.
All variants based on the device are OTP programmed for specified processor; there is no any drop-in replacement for any specified variant; including the TPS65910A3A1RSLR.
Part Number: TPS65320-Q1 This thread applies to TPS65320-Q1.
There is no debounce time on the UV/OV for this device; it's just a Schmitt trigger after a UV/OV comparator.
For most Impedance Track TI battery gauges, a smoothing engine is used to help minimize jumps in the State of Charge (SoC) reported by the gauge. During normal operation of the gauge Full Charge Capacity (FCC) and Remining Capacity (RC) are calculated…
Other Parts Discussed in Thread: GPCCHEM , BQSTUDIO To most efficiently help debug State of Charge accuracy issues, problems encountered during the learning cycle process, or any other function related to the gauge like protection, there is some information…
Other Parts Discussed in Thread: GPCCHEM Some applications require a reduction in the charging voltage, one reason can be to increase the cycle life of the battery.
Reducing the charging voltage will often cause some discrepancies with the State of…
Other Parts Discussed in Thread: EV2400 When looking for the correct chemistry ID for Impedance Track gauges, the GPCCHEM tool should be used. This tool helps find the best matching chemistry ID for the battery. The chemistry ID contains the baseline…
It is common to verify the accuracy of the gauge SoC after learning cycles or battery characterization by doing some math on the discharge logs for capacity and comparing it with the gauge’s predictions.
The voltage range used to define 100% and 0%…
