ABLIC reveals industry’s smallest high-side switch,  helps reduce ECU size 

by Autocar Pro News Desk , 23 Jun 2021


The Tokyo-based ABLIC , a MinebeaMitsumi-owned company, today launched the S-19682/3 Series of high-side switches for automotive use.

A high-side switch is a semiconductor that uses external signals to turn circuits on and off, thereby controlling the power supply by turning the switch on and off. Since the S-19682/3 Series high-side switch for connection diagnosis launched today comes with a current monitor function, the ECU can easily monitor current flowing through cameras and antennas. Also equipped with a current limit function, it prevents the flow of overcurrent to provide safer design.

As a one-channel per package product, the S-19682/3 Series uses the industry’s smallest HSNT8 (2.0x3.0xt0.5mm) package and therefore has a footprint per channel that is the industry’s smallest when compared to multi-channel products. Small size contributes to design freedom and equipped with the earlier mentioned connection diagnosis function, this Series is fully equipped to meet the automotive requirements of the latest ADAS/AD systems.

The company says the S-19682/3 Series is PPAP (Production Part Approval Process)-capable and also meets the AEC-Q100 Grade1 (Automotive Electronics Council) quality standard for automotive ICs



Applications
According to ABLIC, the ultra-small HSNT-8 facilitates connection diagnosis of automotive camera modules, ECUs for automotive surround cameras, remote LNA phantom power supplies for GPS antennas and other devices, ADAS locators, eCall and also car navigation/audio systems.

It is targeted at ECUs that require connection diagnosis of external cameras, antennas and sensors. For instance,  ADAS ECU,  camera ECU, telematics control unit, IVI (In-vehicle infotainment system), car navigation system and car audio system.
