LTC6803IG-2#3ZZPBF

Overview

The LTC6803IG-2#3ZZPBF is a multicell battery stack monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4 V to 55 V and draws a typical operating current of 780 uA. The device provides a regulated output voltage of 5 V with an output current capability of 8 mA. Designed for lithium-ion battery protection, it is housed in an SSOP-44 package suitable for surface mount installation. The component functions reliably across an industrial temperature range from -40 C to +85 C.

Feature Summary

• Monitors multiple cells in high-voltage battery stacks
• Supports passive cell balancing via resistive loading
• Enables cascading connections for extended monitoring ranges

Applications

• Lithium-ion battery stack monitoring
• Battery protection systems
• Electric vehicle power management

Procurement Notes

Verify the specific suffix #3ZZPBF against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer datasheets. Check current availability as distribution channels may indicate restricted supply or limited stock conditions.

Selection Notes

Select this variant when a wide input voltage range up to 55 V is required for the power supply. Ensure the SSOP-44 package fits the PCB layout constraints. Compare against the HG grade if operation above 85 C is necessary, as the IG grade is limited to that maximum temperature.

Part Context

This part belongs to the LTC6803 series of battery monitors. It shares functional similarities with other members like the LTC6803HG-2#3ZZPBF but differs in thermal specifications. The series supports daisy-chaining for monitoring large battery arrays in industrial and automotive applications.

Replacement Considerations

The LTC6803HG-2#3ZZPBF serves as a higher temperature grade alternative. Verify package compatibility and electrical parameter alignment before substitution.
