Single-cell Li-Ion charger with USB input and 1.5A ceiling
The Texas Instruments BQ24032RHLRG4 is a single-cell linear battery charger IC from the bqTINY™ III family, designed for Lithium Ion/Polymer packs with a 4.2V termination voltage. It accepts power from a USB port or a DC adapter up to 16V and delivers a programmable constant charge current with a 1.5A maximum ceiling. The device integrates over-temperature, reverse-current, and short-circuit fault protection, and includes programmable current and timer features for charge management.
Charge current programming and thermal envelope
The charge current is constant and programmable via an external resistor (ISET pin), allowing the designer to set the rate anywhere below the 1.5A maximum.
The BQ24032RHLRG4 carries an Obsolete product status per the manufacturer.
