The BQ24075 is a 1.5 A standalone linear Li-ion battery charger with dynamic power-path management for USB- and adapter-powered portable devices.
Product Overview
The BQ2407x family integrates a Li-ion linear charger and system power-path management for space-constrained portable applications. It operates from a USB port or AC adapter and supports up to 1.5 A charge current. Input voltage protection and dynamic power management (VIN-DPM) prevent damage to misconfigured USB supplies, while the device remains USB-IF inrush compliant.
Newfly supplies verified, RoHS-compliant BQ24075-class charger ICs with cross-reference and BOM-matching support for production sourcing.

FAQ
Q: Does the BQ24075 support power-path management?
A: Yes. Dynamic power-path management (DPPM) lets the system draw power from the input while charging the battery simultaneously.
Q: What is the input voltage range?
A: 4.35 V to 6.4 V, suitable for USB ports and standard adapters.
Q: Can you provide a cross-reference?
A: Yes. Share your BOM and Newfly will suggest compatible power-path battery charger ICs.
