DAtA sheet conventions
• VPINNAME and IPINNAME represents the voltage on a pin
or the pin current; VEQ = EQ Pin Voltage.
• Hexadecimal numbers are prefixed with 0x; 0x10 is a
hexadecimal 10
• Register symbol names will be capitalized. Symbols
within a register will be lower case;
en_meas_sys_valid_alert is bit 15 in register
EN_LIMIT_ALERTS (0x0D)
• LiFePO4 is lithium iron phosphate, Li-Ion is used for
both lithium-ion and lithium-ion polymer
• Lithium chemistries refers to LiFePO4 , lithium-ion, and
lithium-ion polymer as a group.
