The I²C interface lets you set charge current, termination threshold, and other parameters in firmware rather than with fixed resistors — useful when the same PCB must support multiple battery capacities. Supply voltage tolerance goes up to 13.5V, so it can handle typical 5V USB input or a 9V wall adapter without an external pre-regulator. The constant-current charging mode is programmable, giving you control over the charge profile for the specific cell. ## Industrial temperature range and fault protection The integrated over-temperature and over-voltage fault protection shuts down the charger if the die gets too hot or the input spikes — one less discrete comparator to place on the board. Without it, the 3A charge current will push the junction temperature above the safe limit in a warm ambient. No end-of-life notification or successor part has been published.","metaTitle":"BQ25601RTWR – TI 1-Cell Li-Ion Battery Charger, I²C, 3A","metaDescription":"Texas Instruments BQ25601RTWR – 1-cell Li-Ion/Polymer charger, I²C programmable, 3A max charge current, -40°C to 85°C, 24-WFQFN.

For multi-cell applications, look at the BQ25601 family's sibling parts or a dedicated multi-cell charger."},{"question":"Is the BQ25601RTWR compatible with LiFePO4 batteries?","answer":"The BQ25601RTWR targets Li-Ion/Polymer chemistry with a 4.2V termination voltage.
