Frequently Asked Questions
What is the maximum charge current of the BQ24195LRGET?
The BQ24195LRGET supports a maximum charge current of 4.5A when powered from a high-current adapter, and 2.5A in standard USB charging mode. The charge current is fully programmable via the I2C interface, allowing fine-grained adjustment from 512mA to 4512mA in 64mA steps to match different battery capacities and thermal budgets.
What applications is the BQ24195LRGET best suited for?
The BQ24195LRGET is optimized for single-cell Li-ion and Li-polymer battery applications including smartphones, tablets, portable power banks, wearables, and IoT devices. Its integrated 5.1V synchronous boost output at up to 2.1A makes it ideal for USB OTG designs, allowing the device to simultaneously charge its own battery while powering connected USB accessories.
Does the BQ24195LRGET support USB OTG (On-The-Go)?
Yes, the BQ24195LRGET features a built-in synchronous boost converter that provides a regulated 5.1V output at up to 2.1A, fully supporting USB OTG operation. This allows a host device to supply power to connected USB peripherals directly from the battery, without requiring an external boost regulator.
What package does the BQ24195LRGET come in, and what are its dimensions?
The BQ24195LRGET is packaged in a 24-pin Quad Flat No-Lead (QFN) package with an exposed thermal pad on the bottom to enhance heat dissipation. The compact QFN footprint is well-suited for space-constrained portable designs and enables efficient thermal management without external heatsinks.
How does the BQ24195LRGET handle input voltage variation from different power sources?
The BQ24195LRGET accepts an input voltage range of 3.9V to 17V, accommodating a wide variety of power sources including 5V USB ports, 9V/12V fast chargers, and wireless charging receiver outputs. Its Dynamic Power Management (DPM) system continuously monitors input voltage and current, automatically limiting charge current to prevent overloading the source adapter.
