Atmel
®
ATA6870 QFN 7mm
7mm
●
Atmel ATMega32HVB
●
12 external N-channel MOSFETs for balancing of battery cells
●
Connectors
●
ISP connector for programming/debugging the Atmel ATMega32HVB
●
Screw connectors for connecting up to 12 battery cells
J9 should never be set while the Atmel ATmega32HVB is being programmed or while it is entering debug mode. It can be
mounted as soon as AVR Studio prompts for additional SPI lines to be connected in debug mode or after the device has
been correctly programmed.
