LTM2810CY-I#PBF

Overview

The LTM2810CY-I#PBF is a complete galvanic digital μModule isolator manufactured by Analog Devices Inc. It integrates a transformer driver on the logic side and an LDO on the isolated side, requiring no external components. The device provides 7500VRMS isolation with a common mode transient immunity of 50kV/µs. It supports I2C communication at up to 400kHz and operates with supply voltages between 3V and 5.5V. The module features a 36-BGA package and handles logic levels from 1.62V to 5.5V.

Feature Summary

• Integrates transformer driver and isolated LDO for complete galvanic isolation without external components
• Provides high common mode transient immunity exceeding 50kV/µs for reliable communication across ground potentials
• Supports flexible digital interfacing with logic supplies ranging from 1.62V to 5.5V independent of main supply

Applications

• Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems
• Industrial automation and control systems
• Metering systems with different ground potentials

Procurement Notes

Verify the specific suffix 'I' confirms I2C master mode compatibility rather than SPI. Confirm the 'CY' temperature grade matches your operational requirements against standard industrial grades. Ensure the BGA package footprint aligns with your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when high-speed I2C isolation is required in space-constrained designs. The integrated power management reduces bill of materials complexity. Consider the 36-BGA package size and thermal characteristics during layout planning to ensure adequate heat dissipation for continuous operation.

Part Context

This part belongs to the LTM2810 family of μModule isolators. Variants like LTM2810-S offer SPI compatibility, while the base LTM2810 covers general digital isolation. The CY suffix typically denotes a specific temperature or performance grade within the Analog Devices portfolio.

Replacement Considerations

LTM2810CY-SPBF offers identical physical and electrical specifications but supports SPI/Digital interfaces instead of I2C. Verify interface protocol compatibility before substitution.
