Hi Satoshi,
Both parts use the same die with different NVM bits set. The BQ24251 does have ENx enabled. BQ24251 input current limit is set per below:
VINDPM is set by the external resistors (need to confirm). If adding a series resistor helps, then…
Part Number: BQ24253 Other Parts Discussed in Thread: BQ24251 , BQ25606 I need to charge a single lithium ion battery. I selected the BQ24253 because it supports both USB through D+ and D- detection and EN1 and EN2 detection. I have been reading through…
Part Number: BQ27532-G1 Other Parts Discussed in Thread: BQ25600 , BQ24251 Hi everybody,
the datasheet of BQ27532-G1 recommends a charger of the BQ2425x series, which is not recommended for new designs. The product page of BQ24251 names BQ25600 and…
Hi Michael,
BQ24250 doesn't support D+/D- but BQ24251 and BQ24253 support D+/D-.
it looks I should ask BQ team that BQ24250 can support BC1.2 or not.
Regards,
Kai
Akash,
Wanted to add the following regarding the bq25890H.
It is possible to also achieve the 500mA current limit by using an ILIM resistor to fix the current limit to 500mA. This way, even if the result of the D+/D- detection is 1A, it will clamp…
Hello,
It took me some time to respond, but I've moved the bq24251 to a new board. I kept only the components in the dotted square, from the schematic attached earlier on the post. D+ and D- were left floating, SDA, SCL, STAT and PG pins were pulled…
