EMC5060
Single-cell Li-Ion Charger IC with System
Power Management
General Description
The EMC5060 is a single-cell Li-ion charger IC with
system power management feature. It charges the
battery and power the system simultaneously. The
maximum charging current (up to 1.5A) is set by
external resistor for fast charging. The output voltage
for the system is regulated to a nominal value (three
different versions available: 4.4V, 5V or 6V); the
actual value of the output voltage depends on the
input voltage from the adapter, the charging
current and the system loading. With the decrease
of the input voltage or the increase of the system
loading current, the output voltage drops. When the
output voltage drops to a predetermined value
(VAPM-REG), the Active Power Management
function is activated and tries to maintain the output
voltage at VAPM-REG; the EMC5060 will suffice the
system loading with first priority and reduce the
charging current temporarily, i.e. under heavy load
condition, the EMC5060 charges the battery with
the remaining available current to keep the output
voltage at VAPM. In this manner, the charge and
discharge cycle of the battery can be reduced.
It is possible that the EMC5060 fails to maintain the
output voltage at VAPM-REG; for example, when the
system loading current exceeds the capability of the
current-limiting AC adapter. In this scenario, the
output voltage drops to the battery voltage, and
the system is allowed to draw current from the
battery.
