EMC5090
2.5A Synchronous Buck Li-ion Battery Charger
General Description
The EMC5090 is a switch mode lithium-ion battery
charger. It utilities a 1.5MHz synchronous buck
converter topology to reduce power dissipation
during charging. The internal MOS switch delivers
current up to 2.5A to charge the battery. The built in
pre-charge safety timer automatically terminates
charging once the adjustable time limit has been
reached. The EMC5090 includes complete charge
termination circuitry, automatic recharge and a
±1% of 4.2V float voltage.
This device is available in packages of TQFN-16L
(4mmx4mm) for space-saving application.
