Utilize the charger peripheral circuit of this chip design and simple, be applicable to very much the compact design needs of portable type electronic product.BQ2057 can dynamic compensation lithium battery group internal resistance to reduce the duration of charging, with optional battery temperature monitoring, utilize battery pack temperature sensor continuous detecting battery temperature, in the time that battery temperature exceeds setting range, BQ2057 closes battery is charged.Inner integrated constant pressure and flow device is with high/low limit current sense and programmable charge current, charged state identification can realize by the LED light of exporting or with master interface, has automatically the characteristics such as charging again, minimum current termination charging, low-power consumption sleep.
Charged state flow process:
The charging of BQ2057 is divided into three phases: precharging state, constant-current charge and constant-voltage charge stage.
The preliminary filling stage is installing battery and is adding after power source,
First BQ2057 checks operating voltage VCC,
In the time that operating voltage is too low, charger enters sleep pattern,
If operating voltage is normal, check that whether battery temperature is at setting range, enter temperature fault pattern if undesired, otherwise detect cell voltage VBAT, when cell voltage VBAT is during lower than low pressure thresholding V (min), BQ2057 with the electric current I PRE of constant current IREG10% to battery pre-charging
Constant-current charge.At complete battery pair preliminary filling or cell voltage VBAT during lower than constant voltage VREG, BQ2057 enters constant-current charge state, now by the pressure drop monitoring charging current on outside sensing resistor RSNS, this resistance can be taked the connected mode on high/low limit, in flash current detecting, RSNS is connected between VCC and SNS pin, in the current detecting of low limit, RSNS is connected between VSS and SNS pin, obtains the feedback of charging current by SNS pin.
Constant-voltage charge.In the time that reaching constant voltage VREG, charging voltage enters constant-voltage charge state.In whole working temperature and operating voltage range, constant voltage precision higher than ± 1%, BQ2057 by VBAT and
VSS pin monitoring battery voltage, stops charging while stopping thresholding I (TERM) when charging current reaches, when cell voltage starts again to charge when again charging threshold voltage V (RCH) automatically.BQ2057, except realizing 4.1V, 4.2V, the 8.2V and the charging of 8.4V voltage of standard, can also realize off-standard voltage charging by dividing potential drop, and its method is the input as BAT pin by the battery partial pressure value of divider resistance realization.
Battery temperature monitoring
BQ2057 realizes the continuous monitoring to battery pack temperature by the voltage of measuring between TS and VSS pin, commonly uses thermistor as temperature sensor, and realizes by divider resistance.The resistance of divider resistance can be according to calculation of parameter.BQ2057 by this voltage and inner V (TS1) and the comparison of V (TS2) threshold voltage to determine whether allow charging.Because outside dividing potential drop and interior door voltage limit are all taking VCC as reference, ensure that temperature sensing circuit is not subject to the influence of fluctuations of working power VCC.In the time that TS pin is linked to VCC or VSS, can forbid the charge function of BQ2057.
Charged state instruction
BQ2057 reports current charged state by tri-state pin STAT: charged state high level, the low level of having charged, temperature fault or sleep state high-impedance state.In the time that STAT pin is connected with single LED or two LED reversal connection mode, can realize the LED instruction of charged state, also can be by STAT mouth and instrument microcontroller interface, microcontroller is realized the intelligent management of instrument by three kinds of states of identification STAT mouth.
