Li-Ion Charge Termination IC Interfaces with PWM Switchers
Design Note 242
Fran Hoffart
Rechargeable lithium-ion batteries are rapidly becoming the battery of choice for many battery-powered
products. These products include notebook computers, PDAs, video camcorders, digital cameras, cellular
phones, portable test equipment and others. Compared
to other rechargeable power sources, Li-Ion batteries
have higher energy density for both weight and volume
and provide longer run time between charges. tery from overtemperature and overcurrent conditions.
In addition, battery packs may also contain back-toback MOSFET switches that disconnect the battery if
an overcurrent condition exists for either charge or
discharge, or if an overvoltage or undervoltage condition exists. Many of these precautions are needed
because lithium-ion cells are easily damaged by both
overcharge and overdischarge conditions. Charging Li-Ion batteries is a relatively simple process.
Apply a current-limited (at a 1C rate) constant voltage
(В±1% tolerance) for approximately three hours, then
stop charging. (C is a battery term used to indicate
the Ampere-hour capacity of a battery). A complete
charge cycle may also include precharge qualiп¬Ѓcation
for battery temperature and precharge qualiп¬Ѓcation for
deeply discharged batteries. LTВ®1510 Battery Charger IC
The LT1510 is a high efп¬Ѓciency switching regulator
power IC designed speciп¬Ѓcally for battery charging …
