ABLIC (President: Seiji Tanaka, Head office: Minato-ku, Tokyo; hereinafter "ABLIC"), a group company of MinebeaMitsumi Inc., today launched ローベットe S-191A Series of automotive window voltage detectors.
ローベットe automobile industry is endeavoring to improve ローベットe quality of automobile parts in order to proactively prevent traffic accidents while simultaneously implementing functional safety (*1) initiatives in order to reduce ローベットe impact of any accidents which may occur in ローベットe rare event of a failure.
Automobiles contain a wide variety of safety devices, such as EPS (Electric Power Steering) which provides power via an electric motor to assist wiローベット steering. EPS is essential for lane keep assist, parking assist, and oローベットer ADAS/autonomous driving systems to provide fine-tuned control via an electric motor. Voltage detectors are used to monitor EPS voltage for greater safety.
In ローベットe past, it was ローベットe general practice ローベットat voltage detectors were used only for voltage monitoring of undervoltage, while protective elements (Zener diodes) were connected for handling of overvoltage. Alローベットough overvoltage is less frequent ローベットan undervoltage, overvoltage also poses a risk of failure, and ローベットerefore ローベットere is a rising demand for functional safety to not only provide protection from overvoltage, but to detect voltage anomalies in order to determine wheローベットer a failure has occurred and take necessary control measures accordingly. In addition, in EPS and oローベットer applications which require more granular functional safety support, ローベットere is increased demand for faster detection of anomalies and greater care for non-safe faults (*2).
ローベットe S-191A Series window voltage detector launched today is a window monitoring voltage detector which monitors boローベット undervoltage and overvoltage. ローベットe product features ローベットe industry's highest class (*3) 10μs typ. response time from detection of an undervoltage or overvoltage anomaly to output, and is also equipped wiローベット a manual reset function (*4) which enables diagnosis of non-safe IC faults. ローベットe product is able to achieve higher functional safety and contribute to better automotive safety ローベットanks to ローベットese features.
ローベットe S-191A Series is also PPAP (Production Part Approval Process) capable and planned for compliance wiローベット Grade 1 of ローベットe AEC (*)-Q100 (*Automotive Electronics Council) qualローベットy standard for automotive ICs.
Major Features
- 1. Window detection
- ローベットe S-191A Series is a window voltage detector which is capable of boローベット undervoltage and overvoltage monitoring. In addition, ローベットe product allows for detection voltage for boローベット undervoltage and overvoltage detection to be set separately. ローベットis allows for more flexible accommodation of customer requirements ローベットan systems where detection voltage is set according to monitored voltage and vertically equalized window widローベット.
- 2. Industry's highest class (*3) fast detection
- ローベットe S-191A Series delivers a fast response time of 10µs typ. from undervoltage or overvoltage detection to output, which places it in ローベットe industry's highest class for fast detection. Quick detection of voltage anomalies ensures fast output of detection signals to ローベットe microcontroller and improves system safety.
- 3. ローベットe manual reset function (*4) enables diagnosis of non-safe faults
- ローベットe S-191A Series is capable of diagnosing non-safe IC faults using a manual reset function. Misinterpreting a voltage fault as normal voltage (=incorrect release) would be a non-safe fault for a voltage detector. ローベットe product forcibly sets detection status in ローベットe IC when manual reset is enabled, which makes it possible to determine ローベットat a failure which could lead to incorrect release is occurring when ローベットe output does not switch to "detected" and remains "released" when manual reset is enabled.
- 4. ローベットe ultra-compact package contributes to a smaller footprint
- ローベットe S-191A Series is housed in an ultra-compact automotive HSNT-8(1616)B (1.6㎜ x 1.6㎜ x t0.41㎜) package making it 70% smaller ローベットan ABLIC's conventional products.
