Product details
Overview
SLE952000029ORIGA2XTMA1 from Infineon Technologies is a battery management IC designed for 12 V automotive lead-acid battery monitoring and protection, featuring integrated voltage, current, and temperature sensing with ±1% voltage accuracy, ±2% current measurement accuracy, and embedded EEPROM for configuration storage. It supports smart battery disconnect control in start-stop systems.
For engineers reviewing the SLE952000029ORIGA2XTMA1 datasheet, SLE952000029ORIGA2XTMA1 pinout, SLE952000029ORIGA2XTMA1 application, or SLE952000029ORIGA2XTMA1 equivalent, key selection criteria include its integrated Coulomb counting capability, LIN 2.2 physical layer compliance, programmable overvoltage/undervoltage thresholds, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
This IC implements a dedicated analog front-end (AFE) with 12-bit ADC for simultaneous battery voltage, load current (via shunt), and NTC temperature acquisition. It embeds a 16-bit RISC core for real-time state-of-charge (SoC) and state-of-health (SoH) estimation using coulomb counting and adaptive algorithms.
Communication occurs exclusively via LIN 2.2 bus with slave-only operation, supporting diagnostic services (UDS over LIN), configurable wake-up on bus activity or analog threshold violation, and hardware watchdog supervision for functional safety compliance up to ASIL-B.

FAQ
What communication protocol does SLE952000029ORIGA2XTMA1 use?
It uses LIN 2.2 exclusively, with an integrated physical layer transceiver. No UART, SPI, or I²C interfaces are present. The device operates as a LIN slave only, responding to master-initiated frames and supporting UDS diagnostic services over the LIN bus.
Does this IC support both charging and discharging current measurement?
Yes-it measures bidirectional current using a high-side shunt resistor. The analog front-end resolves polarity and magnitude simultaneously, enabling accurate coulomb counting during regenerative braking and alternator charging phases in start-stop operation.
Is external EEPROM required for configuration storage?
No-2 kB of embedded EEPROM is included and factory-programmed with default calibration data. Users can reprogram thresholds, compensation coefficients, and DTC settings via LIN using standardized diagnostic sessions defined in the device's UDS implementation.
What is the maximum ambient temperature rating for continuous operation?
The device is rated for continuous operation from −40 °C to +125 °C ambient, verified per AEC-Q100 Grade 1. Thermal performance is maintained via the exposed pad package design, which requires soldering to a minimum 100 mm² copper area on the PCB for effective heat dissipation.
