Constant Current Charging Mode

Once the battery voltage has exceeded the UVLO threshold the charger will switch to the constant

current charging mode. The MT6305 allows 160mV (typically) across the external current sense resistor.

This constant current can be calculated.

If the voltage of Li-ion battery is below 4.2V (5.1V for NiMH battery), the battery will be in the constant

current charging mode.

Constant Voltage Charging Mode

This mode is only applied to Li-ion battery charging. If the battery has reached the final charge voltage, a

constant voltage is applied to the battery and keeps it at 4.2V. The charge termination is determined by

the baseband chip internally, which will pull the CHRCNTL low to stop the charger. Once the battery

voltage exceeds 4.3V of Li-ion battery (5.1V of NiMH battery), a hardware over voltage protection (OV)

should be activated and turn off the charger block of MT6305.

Pulsed Charging Algorithm

MT6305 is available to pulsed top-off charging algorithm by the CHRCNTL pin. The control signal is from

baseband chipset to limit the charging duty cycle. This charging algorithm combines the efficiency of

switch-mode chargers with the simplicity and low cost of linear chargers.

Battery Voltage Monitor

As the Table 2 shown, the relations of battery voltage and charger control signals are listed. When Vbat <

3.2V, an UVLO signal is active low. When Vbat >= 4.3, an OV signal is active and terminates charging.

The disconnection of battery could be detected by BATDET pin. BATDET is pulled high internally when

battery disconnected and terminates charging immediately.

Notes: OV terminates charging at 4.3V for Li-ion battery or 5.1V for NiMH battery.
