The charge control is based on a patented multiple ramp A/D conversion method that allows the recognition of dV/dt with a sensitivity of better than 0.5 mV/min. The charging is monitored by a timer as an additional safeguard. A noise suppression of more than 60 dB prevents an overcharging with exceptional accuracy which guarantees a long battery lifetime, despite of high charging rates.The IC can be configured to charge one or two 1.2V cells.   PDF The functionality of this ASIC can be extended on customer´s request. Additional components can be integrated to support other parts of the system, so electronics components can be economized on the PCB. For example a timer will switch off a motor after a fixed time or an integrated DC / DC converter transforms the battery voltage to a desired value. Precise sensor amplifiers are able to convert the signals of pressure sensors, temperature or photo sensors, a motor speed can be controlled by a pulse width modulation (PWM) and also LED drivers are available. Typical applications for the battery controller ASIC are electrical toothbrushes, mobile phones, notebooks, shavers, battery driven toys and household appliances.
