LTC6802IG-1#3ZZPBF

Battery Management Overview

The LTC6802IG-1#3ZZPBF is a battery stack monitor from Analog Devices, designed for multicell lithium-ion battery management. It operates within a supply voltage range of 4 V to 50 V and draws a typical operating current of 800 uA. The device provides a regulated 5 V output capable of sourcing 8 mA. It is housed in a 44-pin SSOP package suitable for surface mount installation. The component functions across an industrial temperature range from -40 C to +85 C.

Battery Management Feature Summary

• Integrated high-voltage input multiplexer for direct cell voltage measurement
• Includes a precision voltage reference and serial interface for data communication
• Supports addressable daisy-chaining for monitoring multiple battery stacks

Battery Management Applications

• Multicell addressable battery stack monitoring systems
• Lithium-ion battery protection circuits
• Industrial power management IC applications

Battery Management Procurement Notes

Verify the specific suffix #3ZZPBF against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with the required operating voltage range of 4 V to 50 V. Confirm that the SSOP-44 package fits the target PCB footprint and thermal requirements for the intended application environment.

Battery Management Selection Notes

Select this part when addressing multiple battery stacks via a serial interface is required. Compare against the LTC6803 series if non-addressable monitoring suffices. Verify AEC-Q100 qualification needs, as the IG-1 variant may differ from the IG-2 automotive grade. Check the 800 uA quiescent current against system power budgets.

Battery Management Part Context

This component belongs to the LTC6802 family of battery monitors. It shares functional similarities with the LTC6803 but differs in addressability features. The IG-1 designation indicates a specific commercial grade variant within the broader product line managed by Analog Devices.
