DESCRIPTION
The MP26060 is a linear, high-performance
single cell Li-Ion battery charger. By integrating
high voltage input protection into the charger IC,
the MP26060 can tolerate an input surge up to
24V.
The device features constant current (CC) and
constant voltage (CV) charging modes with
programmable charge currents (85mA to 1A),
programmable battery full threshold, thermal
protection, battery temperature monitoring,
reverse current blocking, and trickle charge.
The device also provides AC adapter power
good and charge status indications to the
system.
MP26060 is available in a 10-pin 3mm x 3mm
QFN package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
