X3102V28

Overview

The X3102V28 is a protection and monitor IC designed for battery packs consisting of four series Lithium-Ion cells. It provides internal over-charge, over-discharge, and overcurrent protection circuitry, along with an internal EEPROM memory, voltage regulator, and drive circuitry for external FETs. The device features software-selectable thresholds via a 3MHz SPI interface and includes a current sense amplifier with selectable gains of 10, 25, 80, and 160 to support high-resolution monitoring by external microcontrollers.

Feature Summary

Software-selectable protection levels and variable detection times
Integrated FET drive circuitry for cell control
Internal analog multiplexer for cell voltage and current monitoring
IDLock™ enabled 4k-bit EEPROM for data partitioning

Applications

Battery pack protection systems
Cell balancing applications
Gas gauge implementations
Lithium-Ion battery management

Procurement Notes

Verify the specific suffix 'V28' against official Intersil or Renesas documentation to confirm package type and temperature range. Ensure compatibility with existing firmware for SPI communication and threshold configuration. Cross-reference with current product portfolios as Xicor was acquired by Intersil, now part of Renesas.

Selection Notes

Select this component for applications requiring precise, software-configurable protection thresholds for 4-cell Li-ion packs. The integrated current sense amplifier allows for cost-effective resolution using standard 10-bit A/D converters. Consider the IDLock feature if permanent storage of battery cell data is required.

Part Context

This component belongs to the X3100 family of battery protection ICs from Intersil (formerly Xicor). The X3100 variant supports 4-cell packs, while the X3101 is designed for 3-cell applications. Both share similar architectures but differ in cell count support. Intersil specialized in analogue devices, focusing on complex consumer and communications products.
