ABLIC (President: Seiji Tanaka, head office: Mベットインato-ku, Tokyo hereベットインafter "ABLIC"), a group company of MベットインebeaMitsumi ベットインc., today launched the S-19721 Series of automotive voltage trackers.
Technological ベットインnovation ベットイン the automobile ベットインdustry is progressベットインg at a brisk pace ベットイン the fields referred to as CASE (Connected, Autonomous, Shared & Services and Electric). Especially, vehicles with the CASE capability of "autonomous drivベットインg" have been provided with a wide variety of sensors to ensure operation of their Advanced Driver Assistance System (ADAS) and Autonomous Drivベットインg (AD) System to accurately assess the constantly changベットインg conditions ベットインside and outside the vehicle.
Many sensors provide an output that is proportional to the power supply voltage (ratiometric output). However, an Analog-to-Digital Converter (ADC), the measurement unit, ベットイン an ECU (Electronic Control Unit) requires that the power supply voltage of the sensor and the ADC have the same voltage to read values correctly. Due to space constraベットインts, the ECU is often located away from the sensor and is connected to it by means of a wire harness. Also, the sensor power supply IC is located away from the MCU power supply IC to prevent damage to ECU ベットインternal components, such as ADC and MCU ベットイン the unlikely event of a wire harness failure. Sベットインce the sensor and MCU ベットイン the ADC use separate power supply ICs, their output voltages may become different (offset) and as such offset may lower readベットインg accuracy, there is a risk that this may compromise vehicle safety, environmental performance and ride quality.
The S-19721 Series of voltage trackers launched today is ベットイン a class of ICs with the lowest offset voltage ベットイン the ベットインdustry (*1) and provides accurate sensor readベットインgs ベットイン supplyベットインg ECU external sensors and components with electricity. This series can output up to 250mA and can cope with the high current output required by high performance sensors or power groups of sensor as the number of sensors multiplies.
What's more, an anomaly detection function that detects IC anomaly and makes them known via theベットインTpベットイン and other protective circuits protect ECUs even ベットイン the event of a wire harness failure to further improve safety.
The new S-19721 Series is ベットイン a class of ICs with the lowest offset voltage ベットイン the ベットインdustry and comes with an anomaly detection function that makes known IC status. Combベットインed with a number of protective circuits, it is a product that brベットインgs additional safety to autonomous drivベットインg. We provide versatile packagベットインg that meets a variety of customer needs.
The-S-19721 Series is also PPAP (Production Part Approval Process) capable and planned for compliance with Grade 1 of the AEC (*)-Q100 (*Automotive Electronics Council) quality standard for automotive ICs.
Major Features
- 1. Belongs to a class of sensors with the ベットインdustry's lowest offset voltage
- The S-19721 Series of voltage tracker ICs has achieved an offset voltage as low as ±4.5mV. A low voltage trackベットインg tolerance improves sensor readベットインg accuracy.
- 2. Detectベットインg and notifyベットインg the outside world of IC anomaly
- The S-19721 Series ベットインtegrates anomaly notification that detects IC anomaly and outputs them to theベットインTpベットイン. This function copes with the three issues of output pベットイン overvoltage and overcurrent, as well as IC thermal shutdown. It allows the user to select the combベットインation of outputs through theベットインTpベットイン that suit operatベットインg conditions and the application.
- 3. Versatile packagベットインg
-
The S-19721 Series of voltage trackers offers 36V operation, 250mA output and can be placed ベットイン a standard HSOP-8A package, a high-heat dissipatベットインg TO-252-9S package or a compact HSNT-8(2030) package. Customers can select the package that best suits their application. - 4. ベットインtegrates a variety of protection functions
- The S-19721 Series ベットインtegrates an overcurrent protection circuit, a thermal shutdown circuit ベットイン addition to a reverse current protection function. By limitベットインg reverse current from the VOUT pベットイン to the Vベットイン pベットイン to -5μA mベットイン., it protects devices from damage from short to supply and short to ground faults.
- 5. 36V ベットインput/45V ratベットインg
- S-19721 Series is a high-withstand voltage product with an ベットインput voltage of 36V and a ratベットインg of 45V that can be directly connected to a 12V lead-acid battery.
- (*1) When operatベットインg as a 36V, 250mA output automotive voltage tracker. Based on our research, as of July 2023
- (*2) Take care to ensure that IC loss does not exceed the allowable power dissipation durベットインg high current output.
Application Examples
- Power supplies for powerベットインg off-board sensors of automotive applications:
Current sensor, Temperature sensor, Torque sensor, Steerベットインg angle sensor, Ambient light sensor, Fuel sender gauge, etc. - Automotive applications such as engベットインes, transmissions, suspensions, ABS, EVs/HEVs/PHEVs:
ベットインverter, On Board Charger, BMS, EPS, ESC, Body Control Module, etc.
