• VPINNAME and IPINNAME represents the voltage on a pin • LiFePO4 is lithium iron phosphate, Li-Ion is used for or the pin current; VEQ = EQ Pin Voltage. both lithium-ion and lithium-ion polymer • Hexadecimal numbers are prefixed with 0x; 0x10 is a • Lithium chemistries refers to LiFePO4 , lithium-ion, and hexadecimal 10 lithium-ion polymer as a group. • Register symbol names will be capitalized. Symbols • When a register name is used in square brackets, this within a register will be lower case; means the 16 bit value associated with that register; en_meas_sys_valid_alert is bit 15 in register For example [VBAT] is the 16 bit ADC measurement EN_LIMIT_ALERTS (0x0D) value of the per cell battery voltage. 4015fb For more information www.linear.com/LTC4015 3 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Order Information Data Sheet Conventions Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram I2C Timing Diagram Operation Applications Information Register Description DETAILED Register Descriptions Typical Applications Package Description Revision History Typical Application Related Parts
