Descriptions
The DIO58056/B/C/D 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 4.2 V for DIO58056, 4.35
V for DIO58056B, 4.4 V for DIO58056C and 4.45 V
for DIO58056D and the charge current and the
terminal current can be programmed externally
with resistors. The input voltage is up to 36 V.
When the input supply (wall adapter or USB
supply) is removed, the DIO58056/B/C/D
automatically enters a low current state, dropping
the battery drain current to less than 1.0 μA.
The DIO58056 is available in a small packages
with DFN2*2-8 and EP-SOIC8. Standard product is
Pb-Free.
Applications
 Wireless phone
 MP3/MP4 player
 Bluetooth device
