A monitoring and protection circuit for 1-cell and 2-cell Li-ion applications that require high security and authentication, accurate monitoring, low cost, and high utilization of the cell energy. The microcontroller includes 16KB self-programming flash program memory, 512-Bytes SRAM, 256-Bytes EEPROM, 1 or 2 cells in series, over-current, high-current and short-circuit protection, 12-bit voltage A/D converter, 18-bit coulomb counter current A/D converter, and debugWire interface for on-chip debug.

The device features autonomous battery protection during charging and discharging, and supports very accurate accumulated current measurements using an 18-bit ADC with a resolution of 0.84µV. It also supports up to 4 MIPS throughput at 4MHz. 1.8 - 9V operation.
