Part Number: BQ25176M Tool/software: Why the VIN_DPM_VIN is just 3.25V? Why the test condition is VOUT=2.9V?
The DPM threshold will vary with the cell voltage?
In general, it should be a fixed value.
Part Number: BQ25176M Tool/software: Hi Team,
I would like to realize the purpose of BIAS pin, I understand it could be applied as shutdown "switch". But if I connect it to GND with resistor, what is the function of BIAS pin at this time?
Part Number: BQ25172
Because the BQ2517x ICs are linear regulators, thermal PCB layout is critical:
Exposed thermal pad: Must be soldered to GND with good coverage.
Thermal vias: Use multiple vias near/under the IC to connect top-side copper…
Part Number: BQ25172
Reduced charge current is most commonly caused by thermal regulation (TREG) limiting output current to protect the die. Other causes include:
A current meter (ammeter) placed in series with the output — even a low-resistance…
Part Number: BQ25172
The BQ2517x family are linear (LDO) chargers . Power dissipation = (VIN − VOUT) × IOUT. When this dissipation causes the die temperature to reach ~125°C (TREG threshold), the device automatically reduces output current to prevent…
Part Number: BQ25172
Charge current is set by a resistor to GND on the ISET pin: IOUT = KISET / RISET, where KISET = 300 ±10% (Ohms·mA) for the BQ2517x family. For example, RISET = 600ohms → IOUT ≈ 500mA. The ISET pin also serves as a real-time current…
Part Number: BQ25172
When no battery is connected, the BQ2517x family does not have a battery detection feature. Instead, the IC charges the output capacitor toward the BAT OVP threshold, then shuts off. The output capacitor discharges back through…
Part Number: BQ25176M Tool/software: Dear All,
I'm designing a (solar) charging circuit with BQ25176M for a LiPo battery. The device with the battery will be located in an outside environment with a chance of temperatures below freezing.
Does the…
