The industry’s first AEC-Q100 Grade 0 qualified* battery monitoring IC
enables highly reliable voltage monitoring!


Feature of S-191ExxxxS Series: Industry's first AEC-Q100 grade 0
Feature of S-191ExxxxS Series: Stable operation even in harsh environment of up to 150°C

 Stable operation even in harsh environments of up to 150°C

The S-191ExxxxS,  a battery monitoring IC, is capable of detecting undervoltage that may cause ECU failure or preventing it from functioning altogether and overvoltage that could seriously damage it.

The S-191ExxxxS, the industry’s first AEC-Q100 Grade 0 qualified* battery monitoring IC, will provide highly reliable voltage monitoring even in harsh environments of up to 150°C.

The growth of EV / HEV has increased the importance of integrating electronics with mechanics. To make this possible, this IC has been designed to ensure stable operation even when on a board placed in a high-temperature environments.
*Based on our research as of November 2021.
  The test is in process and scheduled to end in August 2022.

Feature of S-191ExxxxS Series: Electrical characteristics guaranteed over wide temperature range

 Electrical characteristics guaranteed over wide temperature range

The S-191ExxxxS guarantees electrical characteristics such as current consumption during operation of 0.9μA typ. and a detection voltage accuracy of ±2.0% over a wide range of -40°C to +150°C.
These characteristics lower ECU standby current and ensure high-accuracy voltage detection.

The 45V withstand voltage of the detection voltage input pin (SENSE pin) eliminates the need for external components such as dividing resistors. The use of the small HSNT-8(2030) package also helps reduce the overall footprint.
