The LTC6804HG-2#PBF is a high-performance battery monitor developed by Linear Technology, now part of Analog Devices. This advanced integrated circuit is specifically designed to measure up to 12 series-connected battery cells for state-of-charge (SOC) and state-of-health (SOH) applications. The LTC6804HG-2#PBF is an essential component for modern battery management systems (BMS), ensuring the safety, efficiency, and longevity of battery packs used in electric vehicles, energy storage systems, and other high-reliability applications.

Key Features:

• Cell Voltage Monitoring: Capable of measuring up to 12 series-connected cells with a total measurement error of less than 1.2mV.
• High Voltage Capability: Designed to withstand up to 1000V common mode voltage, which makes it suitable for high voltage battery stacks.
• Robust Communication: Features a robust 2-wire isoSPI communication interface that ensures reliable data transfer even in noisy environments.
• Temperature Measurements: Integrated temperature sensing for monitoring the thermal conditions of the battery pack.
• Daisy Chain Configuration: Multiple LTC6804 devices can be connected in series, allowing for the monitoring of an extended number of cells in large battery packs.
• Configurable Fault Detection: Includes overvoltage, undervoltage, and open-wire detection to protect the battery pack from unsafe operating conditions.

Applications:

• Electric and Hybrid Electric Vehicles (EV/HEV)
• Energy Storage Systems (ESS)
• Backup Power Systems
• Uninterruptible Power Supplies (UPS)

The LTC6804HG-2#PBF is available in a 44-lead plastic SSOP package and is rated for operation from -40°C to 125°C, ensuring reliable performance across a wide range of temperatures. Its high level of integration and advanced features make it an ideal solution for precise battery monitoring in critical applications where safety and efficiency cannot be compromised.
