Data Sheet Conventions
• V_PINNAME and I_PINNAME represents the voltage on a pin
or the pin current; V_EQ = 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;
• 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.
en_meas_sys_valid_alert is bit 15 in register
EN_LIMIT_ALERTS (0x0D)
4015f
