Descriptions
The DIO58011/B is a complete constant-current /
constant voltage linear charger for single cell
Lithium-Ion batteries. No external sense resistor is
needed, and no blocking diode is required due to
the internal MOSFET architecture. Thermal
feedback regulates the charge current to limit the
die temperature during high power operation or
high ambient temperature. The charge voltage is
fixed at 4.2V for DIO58011 and 4.35V for
DIO58011B, and the charge current and the
terminal current can be programmed externally
with resistors. The input voltage is up to 36V.
When the input supply (wall adapter or USB
supply) is removed, the DIO58011/B automatically
enters a low current state, dropping the battery
drain current to less than 1.0μA.
The DIO58011/B is available in a small package
with DFN3*3-10. Standard product is Pb-Free.
Applications
 Wireless phone
 MP3/MP4 Player
 Bluetooth device
