Part Number: BQ25302 Other Parts Discussed in Thread: BQ25303J , , BQ25306 , BQ25300 When battery is shorted, if the high-side FET (HSFET) of the charger turns on then there will be a direct low impedance path to GND resulting in high current through the…
Part Number: BQ25300 I used bq25300 as battery charge IC, but when we power with vbus as 6.8V, the REGN output 0.28V. It is abnormal cause the ic can not work。
We can satisfy the power on conditions of REGN
1. Vbus> Vbat+Vsleep Vbat=3.6V
2. POL floating…
Part Number: BQ25302 Other Parts Discussed in Thread: BQ25303J , , BQ25306 , BQ25300 The battery chargers BQ25300, BQ25302, BQ25306, BQ25303J control the charging enable and disable by the /EN and POL pins.
To enable charging, /EN and POL need to have opposite…
Part Number: BQ25300 Other Parts Discussed in Thread: INA181 Hi,
I am designing a single cell charger with the charger IC being the BQ25300 and a boost converter at the output in order to increase the voltage from the battery range 3.0-4.2V to a stable…
Part Number: BQ25300EVM Other Parts Discussed in Thread: BQ25300 I want to use a 12V 1A input supply instead of 5V 3A to this board. "Power Supply #1 (PS1): A power supply capable of supplying 5 V at 3 A is required. While this part can handle larger…
Part Number: BQ24010 Other Parts Discussed in Thread: BQ25300 , BQ24040 , BQ25170 Hi, Good day. Our customer wants to know how should they terminate the STAT1, STAT2, and PG pins if unused. Also, do we have a similar product that is newer? Is BQ25300 a good…
Charger IC (which is a part that needs 1.8A) is also powered from VBUS, so I assume everything is OK then? Simple state diagram: battery needs to be charged -> plug USB -> TUSB320 connects Rd, then it receives power and measures available current -> TMUX1309…
