Part Number: BQ25723 Hello,
We are currently running into an issue where our charger ICs seem to be failing.
The chargers are initially working/charging fine.
The failure mode we are seeing is pin 31 - HIDRV1 - is shorted to GND, pin 28 - REGN - is ~1…
Part Number: BQ25723 I have a BQ25723 in a design, and have verified that by writing the charge current register, charging is enabled.
The issue I have is that once the external power source is removed, charge current goes to zero (which is reasonable…
Hi Christopher,
Thank you for replying. My question was related to this application. which pins are used on the PD side when I use the TPS25750 (Page 54).
Part Number: BQ25723 Hi Team,
Several questions about BQ25723 VSYS_TH2.
If we set VSYS_TH2 = 3.2V then when Vsys below 3.2V it will trigger PROCHOT? Or it will not trigger only when VAP mode is enable ?
For the protection function when Vsys is too low…
