Overview
ESMT 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.
Typical Application Features „ 2.
5A maximum Charge Current „ No external MOSFET, sense resistor or blocking Diode Required „ Programmable Trickle Charge Termination Timer „ Programmable Charge Current „ Programmable End-of-Charge Current „ Automatic Recharge „ Thermistor Input for Temperature Qualified Charging Applications „ PDAs, Tablet, Cell Phone...
