ATmega32HVB

In Production

A monitoring and protection circuit for 3-cell and 4-cell Li-ion applications that require the highest safety including safe authentication, low cost, and high utilization of the cell energy. The microcontroller includes 32KB self-programming flash program memory, 2KB SRAM, 1024-byte EEPROM, 2, 3 or 4 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 A/D converter with a resolution of 0.84µV. It also supports up to 8 MIPS throughput at 8MHz,. 4-25V operation.
