ABLIC Unveils Battery Monitoring ICs for Automotive and Industrial Applications

ABLIC, has unveiled the S-19193 Series, a cutting-edge line of 3 to 6-cell automotive battery monitoring protection ICs designed to enhance the safety and reliability of Battery Management Systems (BMS) in electric vehicles (EVs), hybrid EVs (HEVs), plug-in HEVs (PHEVs), e-bikes, and industrial applications.

These ICs address the growing demand for functional safety compliance with the ISO 26262 standard for automotive electronics, ensuring safety through fail-safe, fail-operational, and fail-degraded methodologies.

Key Innovations and Features

  1. Secondary Monitoring for Fail-Operational BMS
    • Enables continued battery monitoring even if the primary system fails.
    • Operates independently of microcontroller (MCU) control, providing a safer backup system.
  2. Enhanced Functional Safety
    • Developed under ISO26262-compliant processes, achieving ASIL-B(D) classification.
    • Supports functional safety design through a downloadable Safety Manual.
  3. Self-Test Functionality
    • Simplified internal failure detection via an external start signal.
    • Enables early identification of potential monitoring function failures.
  4. Cascade Functionality
    • Allows seamless integration with adjacent S-19193 Series ICs using a photocoupler.
    • Simplifies circuit design for high-voltage BMS with multiple serially connected batteries.
  5. Robust Specifications
    • Overcharge detection voltage: 2.50 V to 4.50 V ±20 mV.
    • Over-discharge detection voltage: 1.00 V to 3.00 V ±80 mV.
    • Current consumption: 20 µA max.
    • Operating temperature: -40°C  to +125°C.
    • AEC-Q100 and PPAP compliant.
  6. Stand-Alone Operation
    • Reduces design complexity by enabling a secondary monitoring circuit without additional MCU intervention.

Applications

  • Automotive: Battery monitoring in automotive, HEVs, PHEVs, and e-bikes.
  • Industrial: Monitoring for electric forklifts, capacitor systems, and other high-voltage equipment.

Commitment to Safety and Quality

ABLIC’s S-19193 Series supports advancements in automated driving technologies by ensuring continuous battery monitoring under fail-operational and fail-degraded conditions. The ICs mitigate risks of joint failure through independent secondary monitoring and adhere to the Production Part Approval Process (PPAP) and AEC-Q100 Grade 1 standards.
