Part Number: BQ25173
Slow charging or reduced current from the BQ25173 is almost always caused by thermal regulation (TREG) . When the supercapacitor starts from 0 V and the input voltage is, say, 5 V, the full input-to-output voltage drop appears across…
Part Number: BQ25173
Yes, two BQ25173 devices can be paralleled to increase total output current (up to 1.6 A combined). The recommended method uses a slight offset in the output voltage setpoints between the two devices: one unit is set slightly higher…
Part Number: BQ25173
The BQ25173 does not have built-in cell balancing . For series-connected supercapacitors, external balancing resistors placed in parallel across each capacitor are the standard recommended approach.
A single-cell supercap (rated…
Part Number: BQ25172
If no NTC temperature monitoring is needed, connect a 10 kOhm resistor from TS to GND . This biases the TS pin within the normal operating range (~350–380 mV with the internal 38 µA current source), preventing any false hot/cold…
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
The VSET and TMR pins on all BQ2517x devices operate as digital bin systems , not analog. At startup, a calibrated current pulse is applied to the pin and the resulting voltage is measured and compared to a lookup table of predefined…
