MP2662

500mA Single-Cell Li-ion Battery Charger

with Power Path Management,

1mA Termination and <1μA Battery Leakage

DESCRIPTION

FEATURES

The MP2662 is a highly integrated, single-cell,

Li-ion/Li-polymer battery charger with system

power path management for space-limited

portable applications. The MP2662 takes input

power from either an AC adapter or a USB port

to supply the system load and charge the

battery simultaneously. The charger function

features pre-charge (PRE.C), constant current

fast charge(CC) and constant voltage (CV)

regulation, charge termination, and auto-

recharge.

Including Battery Temperature Monitoring

and Programmable Timer

The power path management function ensures

continuous power to the system by

automatically selecting the input, battery, or

both to power the system. This function

features a low dropout regulator from the input

to the system and a 100mΩ switch from the

battery to the system. Power path management

separates the charging current from the system

load, which allows for proper charge termination

and keeps the battery in full-charge mode.

Safety-Related Certification:

The MP2662 provides a system short-circuit

protection (SCP) function by limiting the current

from the input to the system and the battery to

the system. This feature is especially critical for

preventing the Li-ion battery from being

damaged due to an excessively high current.

An on-chip battery under-voltage lockout

(UVLO) cuts off the path between the battery

and the system if the battery voltage drops

below a programmable battery UVLO threshold.

This prevents the Li-ion battery from being

over-discharged. An integrated I²C control

interface allows the MP2662 to program the

charging parameters, such as input current limit,

input minimum voltage regulation, charging

current, battery regulation voltage, safety timer,

and battery UVLO.

IEC 62368-1 CB Certification
