Hot modulation circuit can device power dissipation ratio is larger or will shuffle temperature control in peace when higher environment temperature
In gamut.Its internal fixed constant-voltage charge voltage is 4.2V, can also be by the resistance adjustment of an outside.In addition, working as
During input power power down, the chip is automatically into the sleep pattern of low-power consumption, and now battery BAT1 consumption is less than 3 microamperes.Its
His function also includes the too low latch of input voltage, recharged automatically, and battery BAT1 monitoring temperatures and charged state/charging terminate
The functions such as state instruction.
The operation principle of the chip is：CN3063 includes the state instruction output end of two open-drain output, and charge shape
State indication endWith charging termination instruction end, when input voltage is more than low voltage test threshold value and battery-end
During BAT voltages, CN3063 starts to charge to battery BAT1, charged state indication endLow level is exported, charging is being represented just
Carrying out.If voltage detecting input FB voltage is less than 3V, charger low current enters line precharge to battery BAT1,
When voltage detecting input FB voltage be higher than 3V when, charger using constant current mode to battery BAT1 charge, charging current by
The 23rd resistance R23 between current monitoring end ISET and earth terminal GND is determined.When voltage detecting input FB voltage connects
During nearly battery BAT1 end modulation voltages, charging current is gradually reduced, and CN3063 enters constant-voltage charge pattern.When input voltage is more than
4.45V, and charging current be reduced to charging terminate threshold value when, charge cycle terminates, charged state indication endOutput
High-impedance state, charging termination instruction endLow level is exported, represents that charge cycle terminates, constant current is filled when charging terminates threshold value
The 10% of electric current.If starting new charge cycle, as long as input voltage is powered off, being then taken in again just can be with.When
Voltage detecting input FB voltage is dropped to when recharging below threshold value, automatically begins to new charge cycle.The height of chip internal
The voltage-reference of precision, error amplifier and resistance pressure-dividing network ensure the error of battery-end BAT modulation voltages positive and negative 1%
Within, meet battery BAT1 requirement.When input voltage power down or input voltage are less than battery BAT1 voltages, charger
Into the sleep pattern of low-power consumption, the electric current of battery-end BAT consumption is less than 3 microamperes, so as to add stand-by time.
