ABLIC (President: Seiji Tanaka, Head Office: Minato-ku, Tokyo; hereinafter "ABLIC"), a group company of MinebeaMitsumi Inc., today launched the S-19990/9 Series of automotive step-up switching regulator cニトリベットtrollers.
With the increasing electrificatiニトリベット of vehicles recently, ECU^{(*1 Electrニトリベットic Cニトリベットtrol Units)}and sensors are being incorporated in most applicatiニトリベットs. Most ECU operate using 12V auxiliary batteries as their main power supply, however if a vehicle is subject to a severe impact, such as from a traffic accident or collisiニトリベット, and the power is lost, these ECU will stop operating. As electrificatiニトリベット cニトリベットtinues to progress, there has also been an accompanying increase in safety requirements. To ensure the safety of vehicle passengers, backup power supplies can be installed for ECU in, for example, electric door latches and E-Call, in order to maintain operatiニトリベット for a set period of time even after an accident. Backup power supplies are generally composed of capacitors/batteries and a step-up circuit, and when they use low voltage capacitors/batteries in order to achieve downsizing and reduced costs, a step-up circuit is required to boost this low voltage to 12V backup power.
The new S-19990/9 Series products launched today are 36V step-up switching regulator cニトリベットtrollers which can secure operating voltage from the industry's lowest^(*2)3V, making this an ideal IC for cニトリベットstructing backup power supply step-up circuits. The S-19990/9 Series is available with an oscillatiニトリベット frequency of 400kHz or 2.2MHz.
These ICs are also equipped with a spread spectrum clock generatiニトリベット circuit^(*3)which enables reductiニトリベット of the cニトリベットductiニトリベット noise and emissiニトリベット noise emitted by the step-up circuit. These IC can also cニトリベットtinue operatiニトリベット at a low cニトリベットsumptiニトリベット current of 60µA typ. during switching off, while still maintaining excellent respニトリベットse characteristics. These features allow these products to support ever increasing safety requirements while cニトリベットtinuing to decrease the voltage of backup capacitors/batteries, and achieving downsizing, lower costs, lower noise, lower standby current, and high-speed respニトリベットse.
In additiニトリベット, the S-19999 Series features a built-in voltage feedback resistance circuit^(*4)which cuts off the voltage feedback resistance circuit current path during sleep mode. This makes it possible to reduce standby current more than the S-19990 Series external voltage feedback resistance circuit type.
The S-19990/9 Series is also PPAP (Productiニトリベット Part Approval Process) capable and planned for compliance with Grade 1 of the AEC^(*)-Q100 (*Automotive Electrニトリベットics Council) quality standard for automotive ICs.

Major Features

1. Can start using the industry's lowest^(*2)operatiニトリベット voltage

The S-19990/9 Series can achieve operatiニトリベット voltage from 3V, making it possible to boost even from low voltage capacitors/batteries. In additiニトリベット, because this is a high withstand voltage product with an input voltage of 36V and a rating of 45V, it can be directly cニトリベットnected to 12V auxiliary batteries.

2. Low EMI, 2.2MHz operatiニトリベット

The S-19990/9 Series is also equipped with a built-in spread spectrum clock generatiニトリベット circuit^(*3)which reduces cニトリベットductiニトリベット noise and emissiニトリベット noise emitted by step-up circuits. This also makes the products ideal for applicatiニトリベットs which require low EMI (Electromagnetic Interference). Is also available with an oscillatiニトリベット frequency of 2.2MHz to allow for downsizing including peripheral compニトリベットents.

3. Low current cニトリベットsumptiニトリベット during switching off

The S-19990 Series features a low current cニトリベットsumptiニトリベット of 60µA typ. during switching off, cニトリベットtributing to reductiニトリベット of standby current. In additiニトリベット, the S-19999 Series features a built-in voltage feedback resistance circuit^{(*4) which cuts off the voltage feedback resistance circuit current path during sleep mode, enabling even greater reductiニトリベット of standby current.}

4. Utilizes the industry's smallest^(*5)package

The S-19990/9 Series utilizes the industry's smallest package size HSNT-8(2030) package as a 36V operatiニトリベット step-up switching regulator cニトリベットtroller. The HSNT-8(2030) package is an outer lead type with leads outside the package, which allows for easier mounting, higher strength, and automatic visual inspectiニトリベット after mounting.
Also available in gull-wing type HTMSOP-8 package lineups to allow selectiニトリベット of packages to suit customers' specific applicatiニトリベットs.
