DESCRIPTION
The MP2603 is a low cost single cell Li-ion
battery charger IC suitable for low charge
current applications. It features constant current
(CC) and constant voltage (CV) charging
modes with programmable charge current
(50mA–150mA), trickle charge and charge
status indication.
The MP2603 is enabled with an input supply
voltage greater than 3.5V. The charger IC is
disabled when unplugged from the AC adaptor.
To minimize the charger’s total solution cost,
the MP2603 does not need an external reverse
blocking diode, a precision current-sense
resistor or a compensation capacitor at the
output. MP2603 is available in a 5-pin TSOT23
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.
