8 Detailed Description
8.1 Charge Controller
8.1.1 General Description
The AS3610/11 device serves as a standalone battery charge controller supporting rechargeable Lithium Ion (Li+) batteries. Requiring only a few e xternal components, a fullPfeatured battery charger with a high degree of flexibility can easily be realized. The main features of the controller are: /square6 Charge adapter detection /square6 Internal voltage regulator /square6 Low current (soft) charging /square6 Low current (trickle) charging /square6 Constant current charging /square6 Constant voltage charging /square6 22V input overvoltage protection /square6 Battery presence indication /square6 Operation without battery /square6 Input current limitation /square6 Input voltage drop regulation F igure 13. Detailed Block Diagram ams AG Technical content still valid

8.1.2 Charging Cycle Description
time is approx. 300msec for rising ChDet and approx. 30msec for falling ChDet signal (debounce_timer =00b).
8.1.2.2 Low current soft charging
rechg_en is set, the trickle charging is started.
8.1.2.4 Constant current charging
8.1.2.5 Constant voltage charging
Constant voltage charge mode is initiated, if the battery voltage has reached the VEOC threshold. ycle is terminated and EOC is set. The termination current may be reduce by a factor of 2 by setting the eoccurr bit to 1.

8.1.3 Charger States
8.1.4 Stop charging conditions
There are multiple safety features implemented that trigger a stop_charging condition: T hese are the following: P Battery temperature too high. If ntc_on =1 and voltage at pin NTC is below VBATTEMP P Timeout timer expired (If c h_timeout >0 and charging time has been exceeded). Can be reset by unplugging the charger, setting chg_en =0 or writing charging_tmax =0 P VBUS_OV exceeded P VBUS_UVLO reached P Die temp>140deg (ov_temp_140 set)
8.1.5 Battery presence indication and operation without battery
After EOC state is reached a timer for NOBAT detection is started. If there is no battery present, the voltage will drop to VNOBAT_REG. Depending o n the load on VBAT and the capacitor on VBAT this might take some milliseconds to 1 second. The charger will restart charging (ConstantCurrent charging) after 100msec. The 100msec dead time is necessary to get a battery oscillation frequency of below 10Hz, if there is no battery present and NTC battery detection is not enabled. If No_bat_det=1 and the NOBAT detection timer is below 2 seconds after reaching EOC state, and this happens 2 times in serial, the state “operation without battery” is entered. If the nobat_ntc_det bit is set the looping described above will be stopped and a NTC detection is started. A pull up current of 0.5uA is applied to NTC. If the NTC voltage is above 1.8V, the state machine stays in the no bat state. If the BATTEMP voltage is below 1.8V, a charging cycle is restarted.
8.1.6 VBUS undervoltage regulation
If the voltage on VBUS drops below Vchg_min the current is regulated down to avoid overloading of the input source.
8.1.7 Charger overvoltage protection
This blocks checks if the charger voltage VBUS is above VBUS_OV. In that case the bit stop_charging is set and the charging is stopped until VBUS i s below VBUS_OV. ams AG Technical content still valid

8.1.8 NTC supervision
This charger block also features a supply for an external NTC resistor to measure the battery temperature while charging. If the temperature is t oo high (voltage on NTC pin is below VBATTEMP_ON) the charger will stop operation (stop_charging=1). When the battery temperature drops, the voltage on NTC pin will rise above VBATTEMP_OFF and the charger will start charging again. This is forming a temperature hysteresis of about 3 to 5°C to avoid an oscillation of the charger. The levels for switching off the charger (ntc_temp: 45ºC or 55ºC) as well as the type of NTC (ntc_10k: 10k or 100k) can be selected via register settings. The battery temperature supervision via the NTC can be switched off (ntc_on = 0). The supply for the NTC will be only on when a charger is detected and ntc_on bit is set.
8.2 Step up converter mode (OTG Boost)
The step down charger can also be used in a boost mode providing an output voltage VBOOST on pin VBUS typ 5.05V. In that mode the current d irection is inverted to the charging mode providing current from the battery to the VBUS pin. To enable that mode, it’s necessary that the charger i s disabled (XEN=1 or chg_en=0) and the bit boost_en is set (and for AS3611 the pin OTG_BOOST=1). The bit boost_lowcurr selects the output current capability between 200mA and 500mA.
8.2.1 Softstart of OTG booster
T here is a softstart implemented to reduced inrush current on the VBAT input. For approx. 1msec after the booster is enabled the o utput current is limited below 100mA. After that startup time the full current is available.
8.2.2 Short(circuit and overvoltage protection circuit
To protect the booster, the battery capacity and the circuit connected to VBUS there are multiple protection circuits implemented: P VBAT drops below 2.6V (typ) P VBUS is above 5.3V (typ) P Booster is in current limit operation (e.g. output VBUS is overloaded or shorted to GND) I f one of these conditions is valid for more that 30msec debounce time (debounce_timer =00b), the booster is stopped and the boost_error bit is set. To restart the booster it’s necessary to set boost_en=0 and 1 again. (For AS3611 the OTG_BOOST pin has to be set to 0 and 1 again). If the die Temp is above 140deg the booster is stopped and restarted automatically when the die temperature drops. 8.3 2(Wire(Serial Control Interface
