ABLIC launches the S-191ExxxxS Series of Automotive High-withstand Voltage Window Battery Monitoring ICs

— The Industry’s First! (*1) AEC-Q100 Grade 0 Compliant ICs(*2)!Capable of High Reliability Voltage Monitoring in Harsh Environments up to 150°C!—



 ABLIC Inc.(President: Nobumasa Ishiai, head office: Minato-ku, Tokyo hereinafter “ABLIC”), a group company of MinebeaMitsumi Inc. today launched the S-191ExxxxS Series of automotive high-withstand voltage window battery monitoring ICs.
 The S-191ExxxxS Series of window battery monitoring ICs launched today are products qualified for the automotive IC quality standard AEC (*3)-Q100 Grade 0(*2). The AEC-Q100 standard classifies products into Grades 0 – 3 depending on their ambient operating temperature range. Grade 0 specifies products capable of operating in low temperatures down to -40°C and up to temperatures as high as 150°C. Since these ICs clear all stress tests for the different grades, ECU, EGR or other systems controlling an automatic transmission (AT) will provide high-reliability voltage monitoring even in harsh high temperature environments.
 In addition, the S-191ExxxxS Series is housed in the ultra-small HSNT-8(2030) (2.0 x 3.0 x t0.5mm) package and is a product that amply meets today’s ever-increasing need for smaller automotive devices.
 Also, power consumption during operation of the S-191ExxxxS Series has been lowered to 0.9μA typ. The ICs operate directly from the battery to lower standby current (*4) making them ideal in systems that require continuous sensing. The S-191ExxxxS Series is also PPAP (Production Part Approval Process) capable.


Major Features 

  1. AEC-Q100 Grade 0 compliant(*2)
  2. Housed in an ultra-small HSNT-8(2030) (2.0mm x 3.0mm x t0.5mm) package
  3. Reduces power consumption during operation to as low as 0.9μA typ.
  4. Full lineup available

 Application Examples

  • Automotive applications such as engines, transmissions, EGR and EV, HEV and PHEV vehicles


    (*1) As a voltage detector (reset IC) product group. Based on our research as of November 2021
    (*2)Test progressing. To be completed in August, 2022
    (*3)AEC = Automotive Electronics Council
    (*4) Standby current: Quiescent current, or current that flows even when the ignition is turned OFF
