11 Battery Charger
11.1 Battery Charger Hardware Operating Modes
The battery charger hardware is controlled by the VM, see Section 11.3.The battery charger has 5 modes:
â– Disabled
â– Trickle charge
â– Fast charge
â– Standby: fully charged or float charge
013 â– Error: charging input voltage, VCHG, is too low
6, 2 The battery charger operating mode is determined by the battery voltage and current, see Table 11.1 and Figure
r 1 11.1.
be The internal charger circuit can provide up to 200mA of charge current, for currents higher than this the CSR8615
tem QFN can control an external pass transistor, see Section 11.5.
