DESCRIPTION  
–
Automatic Power Path Selector Between  
Adapter and Battery  
The bq24133 is highly integrated stand-alone Li-ion  
and Li-polymer switch-mode battery charger with two  
integrated N-channel power MOSFETs. It offers a  
constant-frequency synchronous PWM controller with  
high accuracy regulation of input current, charge  
current, and voltage. It closely monitors the battery  
pack temperature to allow charge only in a preset  
temperature window. It also provides battery  
detection, pre-conditioning, charge termination, and  
charge status monitoring. The thermal regulation loop  
reduces charge current to maintain the junction  
temperature of 120°C during operation.

Battery Thermistor Sense Hot/Cold Charge  
The bq24133 charges a one, two, or three cell Li-Ion  
battery in three phases: precondictioning, constant  
current, and constant voltage.

–
Input Over-Voltage Protection with  
Programmable Threshold  
Cycle-by-Cycle Current Limit  
Charge is terminated when the current reaches 10%  
of the fast charge rate. A programmable charge timer  
offers a safety back up. The bq24133 automatically  
restarts the charge cycle if the battery voltage falls  
below an internal threshold, and enters  
low-quiescent current sleep mode when the input  
voltage falls below the battery voltage.

Small QFN Package  
The bq24133 features Dynamic Power Management  
(DPM) to reduce the charge current when the input  
power limit is reached to avoid over-loading the  
adapter. A highly-accurate current-sense amplifier  
enables precise measurement of input current from  
adapter to monitor overall system power.
