GENERAL DESCRIPTION

50m⍀  
The ADP3820 is a precision single cell Li-Ion battery charge  
controller that can be used with an external Power PMOS de-  
vice to form a two-chip, low cost, low dropout linear battery  
charger. It is available in two voltage options to accommodate  
Li-Ion batteries with coke or graphite anodes. The ADP3820’s  
high accuracy (±1%) low shutdown current (1 µA) and easy  
charge current programming make this device especially attrac-  
tive as a battery charge controller.

Charge current can be set by an external resistor. For example,  
50 mΩ of resistance can be used to set the charge current to  
1 A. Additional features of this device include foldback current  
limit, overload recovery, and a gate-to-source voltage clamp to  
protect the external MOSFET. The proprietary circuit also  
minimizes the reverse leakage current from the battery if the  
input voltage of the charger is disconnected. This feature elimi-  
nates the need for an external serial blocking diode.

The ADP3820 operates with a wide input voltage range from  
4.5 V to 15 V. It is specified over the industrial temperature  
range of –20°C to +85°C and is available in the ultrasmall  
6-lead surface mount SOT-23-6 and 8-lead SOIC packages.
