1. Description
LTC®6813-1 is a multi-cell battery pack monitor Can measure up to 18 batteries connected in series The total measurement error is less than 2.2mV. cell The measurement range of 0V to 5V makes LTC6813ILWE-1#3ZZPBF Suitable for most battery chemistries. All 18 cells are fine Measured in 290µs, a lower data acquisition rate can Selected as high noise reduction. Multiple LTC6813-1 devices can be connected in series, Allows simultaneous monitoring of long and high Voltage battery pack. Each LTC6813-1 has an isoSPI Interface for high-speed, radio frequency immunity, and long-distance communication. Multiple devices connected in chrysanthemum A chain connected to one host processor of all devices. The daisy chain can be operated in both directions to ensure Communication integrity, even if there is a failure Communication path. The LTC6813-1 can be powered directly from a battery pack or isolated power supply. LTC6813-1 Including the passive balance of each battery, with a separate PWM duty cycle control of each battery. Other features Including an on-board 5V regulator, nine universal I/O lines and sleep mode, where current consumption Reduced to 6µA

5. Application information
If the primary inductance is too low, The pulse amplitude will start to decrease and decay Pulse period. When the pulse drop is severe enough, The effective pulse width seen by the receiver will be greatly reduced, thereby reducing the noise margin. Some decline is acceptable as long as it is a relatively small percentage Total pulse amplitude. Leakage inductance is mainly Affect the rise and fall time of the pulse. Slowly rising And the fall time will effectively reduce the pulse width. pulse The width is determined by the receiver as the time of the signal It is higher than the threshold set by the ICMP pin. Rise slowly and The fall time cuts into the timing margin. Generally best Keep the pulse edge as fast as possible. When evaluating Transformers, it is also worth noting that parallel windings capacitance. Although the transformer has a very good CMRR At low frequencies, this suppression is reduced at high frequencies, mainly due to the capacitance between the windings. When choosing a transformer, it is best to choose A kind of parallel winding capacitance as little as possible. When choosing a transformer, it’s also important Choose a component with a sufficient isolation level application. Rated working voltage of transformer It is a key specification when selecting parts for the application. Interconnect daisy chain links between LTC6813-1 The device sees a stress of <90V in a typical application; ordinary Pulse and LAN type transformers are sufficient. connect For the LTC6820, a higher operating voltage rating may usually be required to obtain good long-term reliability. usually, Match the working voltage to the entire voltage The battery pack is conservative. Unfortunately, the transformer Suppliers usually only specify a one-second high-voltage test, This is not equal to the long-term ("permanent") rating of the part. For example, according to most security The standard 1.5kV rated transformer is expected to handle 230V continuously, while the 3kV equipment can 1100V long-term, although the manufacturer may not always Prove these levels (see actual supplier data for specific). Generally, the higher voltage transformer is Known as "high insulation" or "reinforced insulation" type supplier. In most applications, common mode chokes are also needed to suppress noise.
