General Description
The bq24130 is highly integrated host-controlled Li-ion and Li-polymer switch-mode battery charge
controllers with two integrated N-channel power MOSFETs. It offers a constant-frequency synchronous
PWM controller with high accuracy regulation of charge current and voltage. It also provides charge status
monitoring.

PWM controller with high accuracy regulation of charge current and voltage. It also provides charge status
monitoring.
The bq24130 automatically enters a low-quiescent current sleep mode when the input voltage falls below
the battery voltage. The bq24130 charges one, two or three cell (selected by CELL pin), supporting up to
4A charge current. The bq24130 is available in a 20-pin, 3.5
