DESCRIPTION 

The EV2602DQ-00B is an evaluation board for 
the MP2602, a linear, high-performance single 
cell Li-Ion battery charger.  

By integrating high voltage input protection into 
the charger IC, the MP2602 can tolerate an 
input surge up to 28V.  

The MP2602 features constant current (CC) 
and constant voltage (CV) charging modes with 
programmable charge currents (200mA to 1A), 
programmable battery full threshold, thermal 
protection, battery temperature monitoring, 
reverse current blocking and trickle charge. The 
device also provides AC adapter power good 
and charge status indications to the system.
