Other Parts Discussed in Thread: BQ51013B , BQ24251 Is there a convenient way to interface the BQ51013B with the charger BQ24251 so that the charge complete message is sent without the use of a host processor?
The schematic in the BQ51013B data sheet Figure…
Other Parts Discussed in Thread: BQ24251 Please let me know about bq24251 taper current setting.
When the device is not in Host mode, I think taper current becomes 10% of charge current set by external resistor. When device receives I2C command, device…
Other Parts Discussed in Thread: BQ24251
Without Battery connected, Output voltage of BQ24251 drops when the input voltage is approx. 4.66V. Load current is approx. 800mA.
Datasheet specifies min. operating voltage as 4.35V. I would like to know why the…
Other Parts Discussed in Thread: BQ24251 Let say I write Register #2 bits 6:4 (I_IN_ILIMIT[2:0]) to 3’b000 (100mA) while in Host mode and then the WD timer expires and the charger goes into Standalone mode. In this mode the current limit will use the external…
Does any I2C access (read or write) cause the charger to enter Host mode?
On page 34 of the datasheet under I_IN_LIMIT the following sentence states “However, when in standalone mode (e.g. no I2C writes have occurred after power up or the WD timer…
Other Parts Discussed in Thread: BQ24251 Hi Team,
I’d Iike to ask about BQ24251 . Is there a recommended thermistor? Data sheet P26 has introduced the JEITA compliant thermistor. Please tell me if there is a specific thermistor name to be recommended…
Other Parts Discussed in Thread: BQ24251 Hello,
I have some questions regarding the bq24251 D+/D- detection algorithm.
(1) The datasheet states that the D+/D- detection algorithm is only active when the device is in standalone mode (e.g. the host is not…
Hi, Customer is considering the TPS24251. Please tell me about the FUNCTION in the data sheet P33.
want to know the concrete situation of 00,10,11. Best Regards, Yusuke/Japan Disty
In section 9.3.4 (BC1.2 D+/D- Detection) of the datasheet the following paragraph states:
The D+/D– detection algorithm is only active when the device is in standalone mode (e.g. the host is not communicating with the device and the watch dog timer has…
Other Parts Discussed in Thread: BQ24251 My requirement is to charge the battery in standalone mode. Whenever VIN input is connected through USB the battery is not detected and charging is not happening. Below are my findings at the respective pins of…
