That 4.5 A ceiling covers fast-charge targets for tablets, power banks, and portable medical gear where the cell can handle a 1 C rate on a 4500 mAh pack. The actual charge current is set via the I²C bus, so the firmware team can tweak the profile without a resistor swap. Input supply tolerance goes to 17 V maximum, which gives headroom for 12 V wall adapters and USB-C PD sources that may spike during hot-plug. The charger steps the input down to the 4.2 V battery regulation voltage using an integrated synchronous buck converter. ## Fault protection — three layers without external parts Overcurrent, overvoltage, and overtemperature protection are built into the die. Overvoltage protection clamps the input if the adapter voltage exceeds the safe limit; overcurrent limits the charge current during a fault; the thermal regulation loop reduces charge current when the die temperature hits the threshold, preventing a thermal runaway in a cramped enclosure. This triple protection means the BOM can skip a separate overvoltage crowbar or a PTC thermistor in many designs. ## Package and temperature grade — rework and environment The operating range is -40 to 85 °C ambient, which covers industrial and outdoor portable equipment but not under-hood automotive. The exposed pad is the thermal path — a four-layer board with a solid ground plane under the pad keeps the junction temperature below the thermal foldback threshold during a 4.5 A charge cycle. ## Lifecycle and sourcing — no LTB risk For a production BOM that needs a 1-cell Li-ion charger with I²C control and 4.5 A capability, this part is a current-generation choice with a clear supply runway.","metaTitle":"BQ24192IRGER 4.5 A Li-Ion Battery Charger, I²C, 24-VQFN","metaDescription":"TI BQ24192IRGER 1-cell Li-Ion/Li-Pol charger, 4.5 A max, I²C control, 17 V input, fault protection.
