LTC6810HG-2#3ZZPBF

Overview

The LTC6810HG-2#3ZZPBF is a high-voltage battery stack monitor manufactured by Analog Devices Inc. It supports up to six series-connected cells with a maximum operating voltage of 20 V per cell. The device operates within a supply voltage range of 20 V and draws a quiescent current of 6.2 mA. It features an extended industrial temperature range from -40°C to +125°C. The component is housed in a 44-lead SSOP package designed for surface-mount installation.

Feature Summary

• Monitors multiple series-connected battery cells in high-voltage stacks
• Supports daisy-chain communication for cascading multiple devices
• Operates reliably across extended industrial temperature ranges

Applications

• Electric vehicle battery management systems
• Hybrid electric vehicle powertrain monitoring
• Industrial energy storage system cell balancing

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and thermal grade. Confirm that the required operating voltage does not exceed the 20 V limit per cell. Ensure the design accommodates the SSOP-44 footprint and thermal dissipation requirements for the specified ambient conditions.

Selection Notes

Select this component when monitoring up to six series cells is sufficient for the application architecture. Consider the HG suffix variant for extended temperature operation compared to standard industrial grades. Evaluate the 6.2 mA supply current against system power budgets. Verify that the daisy-chain interface meets the communication speed requirements of the host controller.

Part Context

This part belongs to the LTC681x family of battery stack monitors, which are designed for high-voltage applications. The HG suffix indicates an extended temperature range variant (-40°C to +125°C), distinguishing it from the IG (industrial) or IZ (automotive) variants. It serves as a core sensing element in multi-cell battery architectures requiring precise voltage measurement.

Replacement Considerations

LTC6810IG-2#3ZZPBF offers identical electrical functionality but with a limited temperature range of -40°C to +85°C. LTC6810HZ-2#3ZZPBF provides automotive-grade qualification with similar temperature specifications. Verify package dimensions and thermal characteristics before substituting.
