1. NTCs seem to be pre-charge path.
2. When the C pin of LM74801-Q1 is left floating, the reverse current blocking functionality is disabled. So, the device will allow reverse current flow through the MOSFETs. Now with the C pin floating, the device will…
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…
Part Number: TPS55288 TPS55288最大输出电流到底多少A?
手册里 Programmable output current limit up to 6.35 A with 50-mA step 指的是啥？
我的输入是5~20V,我需要输出10A，TPS55288是否支持？请问有没有类似设计可以参考
Part Number: TPS92200
We plan to use it in two cases as follows. Case 1: VIN 12V, VOUT 9.7V, IOUT 180mA
Case 2: VIN 12V, VOUT 9.4V, IOUT 420mA
I want to use the same circuit by changing only the inductor and current limiting resistor. In both cases,…
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…
TPS255x parts enter constant current mode during current limit condition; TPS255x-1 parts latch off。
另外，在datasheet 9.3.1 Overcurrent Conditions部分也有详细介绍二者区别。

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--4…
