39 / 67 page  AS3515 V15 austriamicrosystems Data Sheet, Confidential www.austriamicrosystems.com Revision 3.1 38 - 66 6.13 Charger 6.13.1 General This block can be used to charge a 4V Li-Io accumulator. It supports constant current and constant voltage charging modes with adjustable charging currents (50 to 400mA) and maximum charging voltage (3.9 to 4.25V). 6.13.2 Trickle Charge If the battery voltage is below 3V, the charger goes automatically in trickle charge mode with 50mA charging current and 3.9V endpoint voltage. In this mode charging current and voltage are not precise, but provide a charger function also for deep discharged batteries. Also the temperature supervision 6.13.3 Temperature Supervision This charger block also features a supply for an external 100k NTC resistor to measure the battery temperature while charging. If the temperature is too high, an interrupt can be generated. 6.13.4 Parameter Table 39 Charger Parameter Symbol Parameter Notes Min Typ Max Unit ICHG_trick Charging Current (trickle charge) BVDD<=3V, CHG_IN = 4.5V - 5.5V 25 50 100 mA VCHG_trick Charger Endpoint Voltage (trickle charge) BVDD<=3V, CHG_IN = 4.5V 0.72* CHG_IN 4.1 V ICHG (0-7) Charging Current BVDD > 3V, ICHG = 150 – 400mA INOM -20% INOM INOM +20% mA VCHG (0-7) Charging Voltage BVDD > 3V, end of charge is true VNOM -60mV VNOM VNOM +30mV V VON_ABS Charger On Voltage IRQ BVDD = 3V 3.1 4.0 V VON_REL Charger On Voltage IRQ CHG_IN-CHG_OUT 170 240 mV VOFF_REL Charger Off Voltage IRQ CHG_IN-CHG_OUT 40 77 mV VBATEMP_ON Battery Temp. high level BVDD >3V 380 400 420 mV VBATEMP_OFF Battery Temp. low level BVDD >3V 480 500 520 mV ICHG_OFF End Of Charge current level BVDD >3V 10% INOM mA IREV_OFF Reverse current shut down CHG_OUT = 5V, CHG_IN = VSS <1 uA BVDD=3.6V; Tamb=25ºC; unless otherwise specified |
