X3102V28T2

Overview

The X3102V28T2 is a battery protection and monitoring integrated circuit designed for lithium-ion battery packs consisting of three series-connected cells. It provides comprehensive fault protection against over-current, over-voltage, under-voltage, and short-circuit conditions to ensure battery safety and longevity. The device operates with a supply current of 5mA and features a maximum operating voltage of 4.99V per cell. Packaged in a 28-pin TSSOP, it supports SPI interface communication for configuration and status reading.

Feature Summary

• Integrated protection against over-current, over/under voltage, and short-circuit faults
• Designed specifically for three-series lithium-ion battery pack configurations
• Supports SPI interface for digital control and monitoring

Applications

• Lithium-ion battery pack management systems
• Embedded systems requiring reliable battery protection
• Industrial automation equipment with multi-cell battery power sources

Procurement Notes

Verify the manufacturer designation as Intersil or Renesas Electronics Corporation, as Intersil was acquired by Renesas. Confirm the package type is 28-TSSOP and that the component is lead-free and RoHS compliant. Ensure the specific suffix V28T2 matches the required pinout and packaging variant for your design.

Selection Notes

Select this component when designing protection circuits for three-series lithium-ion battery configurations. It is suitable for applications requiring integrated fault detection and SPI-based monitoring. Consider the 28-pin TSSOP package constraints and the 5mA supply current requirement during PCB layout and power budgeting.

Part Context

The X3102 belongs to the X3102 family of battery protection ICs from Intersil (now Renesas). These devices are specialized for managing multi-cell lithium-ion batteries, offering both protection and monitoring functions. The X3102V28T2 variant specifically denotes the 28-pin TSSOP package version within this product line.

Replacement Considerations

Check for direct substitutes within the X3102 family from Renesas. Verify compatibility with existing firmware if SPI commands are used. Ensure any replacement maintains the 28-TSSOP footprint and supports three-series lithium-ion cell protection requirements.
