Battery identification BSI

Battery Bsi Resistor

Different battery types are identified by a pull-down resistor inside the battery pack. In the baseband area of the transceiver, the BSI line has a 150k pull-up to VBB. The MCU can identify the battery by reading the BSI line DC-voltage level with a CCONT (N201) A D-converter. Battery Size Indication pull-up to VBB 150k 5 SIM Card removal detection Treshold 2.4V VBB22.8V Indication resistor for BMC-2 battery (640mAh, NiMH) Indication resistor for BMC-3 battery (900mAh, NiMH) Indication resistor...

Battery temperature BTEMP

The battery temperature is measured with a NTC inside the battery pack. The BTEMP line inside transceiver has a 100k pull-up to VREF. The MCU calculates the battery temperature by reading the BTEMP line DC-voltage level with a CCONT (N201) A D-converter. Battery temperature indication 100k pull-up resistor to VREF in phone Battery package has NTC pull down resistor 47kQ. + -5 +25 C , B 4050+ -3 IBI-pulse,Phone power up by battery (input) Power up pulse width Figure 12 Standard Battery, BTEMP...
