Yes. Series and parallel combinations of batteries should be the same battery model. Two parallel batteries look like a single battery with twice the capacity of the batteries that make it up. Depending…
Yes. The DS277X can measure voltage, temperature, and current, and estimates available capacity for rechargeable both lithium-ion (Li+) and Li+ polymer batteries. LiFePO4 batteries are more difficult to…
We do not guarantee the contents of the registers in the DS277X unless explicitly stated otherwise in the data sheet. We assume that most customers will want to program the DS2777 during pack assembly…
Equations to calculate the quantities in question are shown below: where:
>FULL50 (mAH) = Characterization value in the EEPROM table (6A and 6B)
>AE/SE Active empty/standby empty = Calculated percentage…
The DS277X measures precision Voltage, Temperature and Current. Available Capacity is determined by combination of Coulomb Count, Discharge Rate, Temperature and Cell Characteristics using Maxims Proven…
Aging data is periodically saved to EEPROM and is decreased at approximately 2.4% per 100 cycles or battery life at 88% after 500 cycles. The aging estimation rate can be adjusted by setting the AC register…
The DS277X family has been used in Commercial and Military Radios, DSLR Cameras, Portable Medical Equipment, Digital Cameras/Video Cameras, 3G Multimedia Wireless Handsets,Portable GPS Navigation Systems…
SHA-1 is used to authenticate that a valid genuine battery pack is used, preventing counterfeit batteries causing possible under performance and damage. SHA-1 is used in some of the DS277X devices and…
