Features
Single chip solution for rechargeable battery management.
Embedded Microchip patented Accuron™ technology provides precise capacity reporting (within 1%) for all rechargeable battery chemistries.
User configurable and "learned" parameters stored in on-chip 128 x 8 EEPROM; fully field re-programmable via SMBus interface.
Integrating sigma-delta A/D converter accurately measures: - Current through sense resistor (15-bits) - High voltage (18V) battery cells dire.
