Single-cell Li-Ion charger with USB interface and AEC-Q100 grade
It integrates a USB-compatible input, programmable charge current up to 1.5 A, and fault protection including over-temperature, reverse current, and short circuit.
Charge current and programmable features
The charge current is constant and programmable via an external resistor, with a maximum of 1.5 A. Programmable features also include a charge timer, allowing the designer to set the termination timeout for the application's battery capacity. The device operates from a supply voltage up to 16 V and charges a single-cell battery pack to 4.1 V.
Package and footprint for automotive PCB layout
Housed in a 20-VFQFN Exposed Pad package (supplier device package 20-VQFN 3.5x4.5 mm), the part is surface-mount and requires a thermal pad on the PCB for heat dissipation.
Obsolete — sourcing through independent distribution
The BQ24030IRHLRQ1 is listed as obsolete by Texas Instruments. For BOM lines requiring this exact order code, procurement must rely on independent distribution channels for last-time-buy or surplus inventory.
