The CB06CRMA is a complete constant-current /constant voltage linear charger for coin batteries. The device contains an on-chip power MOSFET and eliminates the need for the external sense resistor and blocking diode. An on-chip adaptive block can adjust charging current automatically based on the output capability of input power supply, so CB06CRMAis ideally suited for solar powered system. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature.

The regulation voltage is internally fixed at 3.3V with 1% accuracy, it can also be adjusted upwards with an external resistor. The charge current can be set externally with a single resistor. When the input supply is removed, the CB06CRMA automatically enters a low power sleep mode , dropping the battery drain current to less than 3uA. Other features include undervoltage lockout, automatic recharge and charging indicator.
