资 源 简 介
The bq24741/2 is a high-efficiency, synchronous battery charger with integrated compensaTIon, offering low component count for space-constrained Li-ion or Li-polymer battery charging applicaTIons. RaTIometric charge current and voltage programming allows high regulaTIon accuracies, and can be either hardwired with resistors or programmed by the system power-management microcontroller using a DAC or GPIOs.
The bq24741/2 charges two, three, or four series Li+ cells, supporting up to 10 A of charge current, and is available in a 28-pin, 5x5-mm2 thin QFN package.
The bq24741/2 features resistor-programmable PWM switching frequency and accurate 150mA trickle charge (with 20 m sensing resistor), which can be enabled via the TRICKLE pin.
