Part Number: BQ25756
Hello TI team,
Recently, I have been using the resistance-programmed BQ25756E as the output for the wireless power transmission (WPT) module. At the beginning, the initial power I input to the BQ25756E was lower than the normal working…
您好
To set the maximum input current using the ILIM_HIZ pin, a pull-down resistor to PGND is used. When using a 2-mΩ RAC_SNS resistor, the input current limit is controlled by: IAC_MAX = KILIM / RILIM_HIZ. The actual input current limit is the lower value…
Part Number: BQ25890 As we know, for BQ25890,IINLIM or IDPM_LIM can be used by DPM. But what's the usage of ILIM pin controlled input current limit? That's to say if the input current limit of Charger is determined by ILIM pin, what will happen when the…
Part Number: BQ25730 When we were testing the FRS function of BQ2730, we found that the output current limit was not determined by the OTG Current register for a short period of time (a few milliseconds) after triggering the FRS. If the test output current…
Part Number: BQ25756 1.使用贵公司该系列产品对超级电容充电，为什么充电一段时间后，电压升高到一定值，就没有输出电流了？并且充电状态仍然为不变“Fast Charge”
2.寄存器配置：
//0010: Charge Voltage Limit：15V
//0050: Charge Current Limit--1A
//0060: Input Current DPM Limit--3A
//0382: Input Voltage DPM Limit-…
Part Number: AWR1843BOOST
The product description states that a power supply greater than 2.5A is required, but the user guide says:（2.5-A current limit），
So, should I choose a power cord greater than 2.5A or less than 2.5A?
Does this plug I have meet…
Part Number: LM61460-Q1
1、In the case of light load, whether the output is normal and whether there is a protection mode for light load
2、According to the Datasheet, when the load current is less than half of the ripple current, it will enter DCM. At…
Part Number: LM3485 Hi Team,
I would like to add a little more information. The power supply settings are: voltage 23.5V, current limit 2.1A. The current is 2.1A when the host is charging. The test is as shown on the right, which meets the current limit…
please share the DS of the transformer to complete the schematic review.
As mentioned above, efficiency and EMI will be a challenge. I recommend using a push pull controller for this case. Push pull controller allows to deliver more power with a limited…
