1.2A Switch-Mode Li+ Chargers with 22V Input  
Rating and JEITA Battery Temperature Monitoring  
General Description  
Features  
S 3.25MHz Switching Li+/Li-Poly Battery Charger  
The MAX8900_ is a high-frequency, switch-mode char-  
ger for a 1-cell lithium ion (Li+) or lithium polymer  
(Li-Poly) battery. It delivers up to 1.2A of current to the  
battery from 3.4V to 6.3V (MAX8900A/MAX8900C) or  
3.4V to 8.7V (MAX8900B). The 3.25MHz switch-mode  
charger is ideally suited to small portable devices such  
as headsets and ultra-portable media players because it  
minimizes component size and heat.  
S JEITA Battery Temperature Monitor Adjusts  
Charge Current and Termination Voltage  
S 4.2V ±±.5ꢀ Battery Regulation Voltage (Alternate  
4.1V Target Available on Request)  
S Adjustable Done Current Threshold  
Adjustable from 1±mA to 2±±mA  
±1mA Accuracy at 1±mA  
Several features make the MAX8900_ perfect for high-  
reliability systems. The MAX8900_ is protected against  
input voltages as high as +22V and as low as -22V.  
Battery protection features include low voltage prequali-  
fication, charge fault timer, die temperature monitoring,  
and battery temperature monitoring. The battery temper-  
ature monitoring adjusts the charge current and termina-  
tion voltage as described in the JEITA* specification for  
safe use of secondary lithium-ion batteries.  
S High-Efficiency and Low Heat  
S Uses a 2.±mm x 1.6mm Inductor  
S Positive and Negative Input Voltage Protection  
(±22V)  
S Up to +2±V Operating Range (Alternate OVLO  
Ranges Available on Request)  
S Supports No-Battery Operation  
S Fault Timer  
Charge parameters are easily adjustable with external  
components. An external resistance adjusts the charge  
current from 50mA to 1200mA. Another external resis-  
tance adjusts the prequalification and done current  
thresholds from 10mA to 200mA. The done current thresh-  
old is very accurate achieving Q1mA at the 10mA level.  
The charge timer is adjustable with an external capacitor.
