DESCRIPTION
The MP26075 is a linear, high performance,
and high efficiency single cell Li-Ion or Li-
polymer battery charger for AC adapter input in
the plug-in, cradle charger applications.
The device will control the AC adapter output
voltage against the battery voltage to increases
energy efficiency. Additionally, MP26075 can
provide very low pre-charge charge current for
deep-discharged battery.
For guaranteed safe operation, MP26075
controls power up sequencing. It ramps-up AC
adapter firstly to limit inrush current when the
adapter plug in. Other safety feature includes
battery temperature monitoring, charge time-out
and fault indications, it also provides
input/output over voltage protection and charge
status indications.
MP26075 is available in QFN 3x3mm package.
FEATURES
Voltage control function for the fly-back
controller
High charge efficiency
Battery voltage options: 4.05V-4.20V.
Low current pre-charge mode
Controlled power-up sequencing

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 power 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 board.
