Frequently Asked Questions
What is the maximum charge current of the BQ24350DSGR?
The BQ24350DSGR supports a programmable charge current of up to 1.5A, set via an external resistor connected to the ISET pin. This makes it suitable for efficiently charging single-cell Li-Ion or Li-Polymer batteries in compact portable devices.
What input voltage range does the BQ24350DSGR support?
The BQ24350DSGR accepts an input voltage ranging from approximately 4.35V up to 6.5V, with integrated overvoltage protection. This allows it to be powered directly from a standard 5V USB source while protecting against transient overvoltage events.
What package does the BQ24350DSGR come in and what are its dimensions?
The BQ24350DSGR is housed in a WSON-8 (DSG) package measuring 2mm x 2mm, making it one of the smallest solutions for single-cell battery charging. This compact footprint is ideal for space-constrained wearables, earbuds, and IoT devices.
Can the BQ24350DSGR be used as a drop-in replacement for other TI charger ICs?
The BQ24350DSGR is pin-compatible with several other Texas Instruments single-cell charger ICs in the WSON-8 package, such as the BQ24090 family. However, always verify regulation voltage, charge current range, and protection thresholds in the datasheet before substituting in a production design.
