Part Number: BQ24172EVM-706-15V Other Parts Discussed in Thread: BQ24172 Hi,
What is the purpose of the 0 Ohms resistor R20 connected in series between the BTST pin and bootstrap capacitor in BQ24172EVM? How this resistor value is calculated if required…
Part Number: BQ24172 HI
I HAVE A CIRCUIT WITH BQ24172 AS CHARGER & ACFET& RBFET P.N CDS17309Q3.
I have designed this board mainly based on BQ24172EVM-706-15V board .
I HAVE NOTICED THAT 30% OF THE MANUFACTURED CARDS HAVE A PROBLEM OF POWER THAT…
Part Number: BQ24170 Other Parts Discussed in Thread: BQ24172EVM-706-15V Hi experts,
Below is the schematic. I found, when the 4.2V x 2 cell battery is abcent, the system voltage is unstable after I changed the input voltage from 12V to 9V. The back-to…

Issue description: TPS25750D Only can be configured as SINK, and cannot be configured as Source in my dev board with the DRP customized…
Hii Jeff,
At the time of initialization, I read all the registers. given below are logs of some voltage, current registers and charger control registers.
[11:04:01:167] Minimal System Voltage set to: 3500mV␊ [11:04:01:201] Charge Voltage Limit set to: 4200mV…
Part Number: BQ24172
Hello,
We are using BQ24172RGYR IC in our design to charge 7.4V 13500mA Lithium Polymer battery.
The input voltage is 12VDC and input current is set max to 1.6A (ACSET) but its only using 1.3A during charging.
The battery charging…
Dear Amrit -JI
Q:What's the start-up load current?
A: Since this PCB is connected to the system’s PCB, and We don’t have other PCBs on hand to measure, I cannot determine the full loading. The system’s PCB is located in our Singapore office…
Hello Ruoxin,
Ruoxin Chang said: NTC to reach 85℃ ~ 100℃
I will assume any where in the range is fine, so I'll pick the middle, 0.4k. R1 will set the voltage and current of NTC. 806 ohms one of many options.
Next to to find the IN- voltage for NTC…
Hello, I tried modifying the example code to use VREFHI also for VREHI, the MCU must have 5V thus is have connected the jumper accordingly.
While using DACOUTB (through example code) at pin 70 of launchXL-F28379D, I am not able to receive any output.…
