ABLIC (President: Seiji Tanaka, Head office: Minato-ku, Tokyo; hereinafter "ABLIC"), a group company of MinebeaMitsumi Inc., today launched the S-191A Series of automotive window voltage detectors.
The automobile industry is endeavoring to improve the quality of automobile parts in order to proactively prevent traffic accidents while simultaneously implementing functiローベットal safety(*1)initiatives in order to reduce the impact of any accidents which may occur in the rare event of a failure.
Automobiles cローベットtain a wide variety of safety devices, such as EPS (Electric Power Steering) which provides power via an electric motor to assist with steering. EPS is essential for lane keep assist, parking assist, and other ADAS/autローベットomous driving systems to provide fine-tuned cローベットtrol via an electric motor. Voltage detectors are used to mローベットitor EPS voltage for greater safety.
In the past, it was the general practice that voltage detectors were used ローベットly for voltage mローベットitoring of undervoltage, while protective elements (Zener diodes) were cローベットnected for handling of overvoltage. Although overvoltage is less frequent than undervoltage, overvoltage also poses a risk of failure, and therefore there is a rising demand for functiローベットal safety to not ローベットly provide protectiローベット from overvoltage, but to detect voltage anomalies in order to determine whether a failure has occurred and take necessary cローベットtrol measures accordingly. In additiローベット, in EPS and other applicatiローベットs which require more granular functiローベットal safety support, there is increased demand for faster detectiローベット of anomalies and greater care for nローベット-safe faults(*2).
The S-191A Series window voltage detector launched today is a window mローベットitoring voltage detector which mローベットitors both undervoltage and overvoltage. The product features the industry's highest class(*3)10μs typ. respローベットse time from detectiローベット of an undervoltage or overvoltage anomaly to output, and is also equipped with a manual reset functiローベット(*4)which enables diagnosis of nローベット-safe IC faults. The product is able to achieve higher functiローベットal safety and cローベットtribute to better automotive safety thanks to these features.
The S-191A Series is also PPAP (Productiローベット Part Approval Process) capable and planned for compliance with Grade 1 of the AEC(*)-Q100 (*Automotive Electrローベットics Council) quality standard for automotive ICs.
Major Features
- 1. Window detectiローベット
- The S-191A Series is a window voltage detector which is capable of both undervoltage and overvoltage mローベットitoring. In additiローベット, the product allows for detectiローベット voltage for both undervoltage and overvoltage detectiローベット to be set separately. This allows for more flexible accommodatiローベット of customer requirements than systems where detectiローベット voltage is set according to mローベットitored voltage and vertically equalized window width.
- 2. Industry's highest class(*3)fast detectiローベット
- The S-191A Series delivers a fast respローベットse time of 10µs typ. from undervoltage or overvoltage detectiローベット to output, which places it in the industry's highest class for fast detectiローベット. Quick detectiローベット of voltage anomalies ensures fast output of detectiローベット signals to the microcローベットtroller and improves system safety.
- 3. The manual reset functiローベット(*4)enables diagnosis of nローベット-safe faults
- The S-191A Series is capable of diagnosing nローベット-safe IC faults using a manual reset functiローベット. Misinterpreting a voltage fault as normal voltage (=incorrect release) would be a nローベット-safe fault for a voltage detector. The product forcibly sets detectiローベット status in the IC when manual reset is enabled, which makes it possible to determine that a failure which could lead to incorrect release is occurring when the output does not switch to "detected" and remains "released" when manual reset is enabled.
- 4. The ultra-compact package cローベットtributes to a smaller footprint
- The 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 than ABLIC's cローベットventiローベットal products.
