LTC4124
100mA Wireless Li-Ion Charger
with Low Battery Disconnect
FEATURES DESCRIPTION Complete Wireless Power Receiver, Li-Ion Charger
and PowerPath™ Controller
nn Wireless Input Power Control and Rectification
nn Wideband Wireless Power Frequency: DC to >10MHz
nn Pin-Selectable Charge Current:
10mA/25mA/50mA/​100mA
nn Pin-Selectable Charge Voltage: 4.0V/4.1V/4.2V/4.35V
nn Pin-Selectable Low Battery Disconnect: 2.7V/3.2V
nn Zero Battery Drain Current in Disconnect/Ship Mode
nn Pin-Selectable Low Battery Pre-Charge Current Enable
nn NTC Input for Temperature Qualified Charging
nn Safety Charge Termination Timer
nn Tiny Total Solution Size with Few Externals
nn Small Thermally Enhanced 12-lead
2mm × 2mm LQFN Package The LTC®4124 is a simple high performance wireless
Li-Ion charger with low battery disconnect. The pinselectable charge current (up to 100mA) and charge
voltage ensure versatility while minimizing the number
of required external components. APPLICATIONS The 2mm × 2mm LQFN package and minimal number of
external components make the LTC4124 well-suited for
low power portable applications where small solution size …
