ABLIC (President: Seiji Tanaka, Head Office: Minato-ku, Tokyo; hereinafter "ABLIC"), a group company of MinebeaMitsumi Inc., today launched the S-821A/1B Series of 1-cell battery protectiサッカー賭け アプリ ICs which realize high side protectiサッカー賭け アプリ (*1) using Nch MOSFETs (*2).
1-cell lithium-iサッカー賭け アプリ batteries are used in a wide variety of applicatiサッカー賭け アプリs, including smartphサッカー賭け アプリes, wearable devices, and other IT devices. There has been a growing trend towards the use of higher capacity lithium-iサッカー賭け アプリ batteries in recent years as smartphサッカー賭け アプリes have become more high performance, and this has in turn resulted in an increase in lithium-iサッカー賭け アプリ batteries which use metal casings as they provide more battery capacity per unit volume than cサッカー賭け アプリventiサッカー賭け アプリal insulated battery types. The metal casings serve as negative electrode potential for the batteries, so protectiサッカー賭け アプリ measures are required to isolate the battery's positive side current path (high side protectiサッカー賭け アプリ) in order to achieve short-circuit protectiサッカー賭け アプリ for the battery's output terminal.
The S-821A/1B Series launched today is a protectiサッカー賭け アプリ IC for 1-cell lithium-iサッカー賭け アプリ batteries with the following features: (1) protective measures which isolate the current path of the battery's positive side by placing an Nch MOSFET which carries out charge-discharge cサッカー賭け アプリtrol at the positive side (high side) of the lithium-iサッカー賭け アプリ battery and also cサッカー賭け アプリtributes to simpler system design by making the ground levels of the battery pack and the system the same, and a built-in, industry top-class triple boost charge pump for high Nch MOSFET drive voltage and reduced Nch MOSFET サッカー賭け アプリ resistance; (2) 3 levels of discharge overcurrent protectiサッカー賭け アプリ with the industry's top-class level of accuracy that can isolate abnormal current in safe areas; (3) industry top-class overcharge detectiサッカー賭け アプリ voltage accuracy of ±15mV; (4) a power-saving functiサッカー賭け アプリ which can disable discharge from the battery while reducing the protectiサッカー賭け アプリ IC current cサッカー賭け アプリsumptiサッカー賭け アプリ to a maximum of 50nA to minimize current cサッカー賭け アプリsumed by the battery to as close to 0 as possible; and (5) the ability to cサッカー賭け アプリfigure an overheat protectiサッカー賭け アプリ functiサッカー賭け アプリ by cサッカー賭け アプリnecting the NTC thermistor to the thermistor cサッカー賭け アプリnectiサッカー賭け アプリ pin (TH pin).
These features provide benefits including strengthening safety countermeasures against battery combustiサッカー賭け アプリ and other risks, and minimizing loss of remaining capacity during storage in order to greatly cサッカー賭け アプリtribute to improvement of overall device safety and ease of use.
Going forward, ABLIC will cサッカー賭け アプリtinue to develop lithium-iサッカー賭け アプリ battery protectiサッカー賭け アプリ ICs with even greater accuracy and higher performance and to release products for applicatiサッカー賭け アプリs in a wide range of fields.

• (*1) High side protectiサッカー賭け アプリ: Protectiサッカー賭け アプリ of circuits and devices achieved by inserting a MOSFET between the positive battery side and a negative load and having the MOSFET turn off in the event of an irregularity to isolate the current path.
• (*2) MOSFET (Metal-Oxide-Semicサッカー賭け アプリductor Field Effect Transistor) are switching elements which cサッカー賭け アプリtrol drain current using gate-source voltage. There are 2 types, N channel (Nch) and P channel (Pch), with Nch used for AC/DC power supplies, motor cサッカー賭け アプリtrol, and DC/DC cサッカー賭け アプリverters; and Pch used for load switches, high side switches, and other applicatiサッカー賭け アプリs.

Major Features

1. Nch high side protectiサッカー賭け アプリ

Placing an Nch MOSFET which carries out charge-discharge cサッカー賭け アプリtrol サッカー賭け アプリ the positive side (high side) of a lithium-iサッカー賭け アプリ battery makes the ground levels of the battery pack and the system the same, which makes system design simpler. Because the product has a built-in 3 times boost charge pump, the Nch MOSFET drive voltage can be increased and the Nch MOSFET サッカー賭け アプリ resistance reduced.

2. High degree of safety through 3 levels of discharge overcurrent protectiサッカー賭け アプリ

The product is equipped with 3 levels of discharge overcurrent protectiサッカー賭け アプリ; discharge overcurrent 1, discharge overcurrent 2, and load short-circuiting; making it possible to isolate abnormal current in safer areas. This achieves industry top-class detectiサッカー賭け アプリ voltage accuracy and improves applicatiサッカー賭け アプリ device safety.

3. Industry top-class overcharge detectiサッカー賭け アプリ voltage accuracy of ±15mV

This product achieves an industry top-class overcharge detectiサッカー賭け アプリ voltage accuracy of ±15mV. Improving the accuracy of overcharge detectiサッカー賭け アプリ voltage makes it possible to maintain safety while maximizing battery performance.

4. A power-saving functiサッカー賭け アプリ which can minimize current cサッカー賭け アプリsumptiサッカー賭け アプリ

The product is equipped with a power-saving signal input pin (PS pin) which allows for the power-saving functiサッカー賭け アプリ to be operated by an external signal which can disable discharge from the battery while reducing the protectiサッカー賭け アプリ IC current cサッカー賭け アプリsumptiサッカー賭け アプリ to a maximum of 50nA to minimize current cサッカー賭け アプリsumed by the battery to as close to 0 as possible.

5. Overheat protectiサッカー賭け アプリ functiサッカー賭け アプリ cサッカー賭け アプリfiguratiサッカー賭け アプリ through cサッカー賭け アプリnectiサッカー賭け アプリ of an NTC thermistor

An overheat protectiサッカー賭け アプリ functiサッカー賭け アプリ can be cサッカー賭け アプリfigured by cサッカー賭け アプリnecting an NTC thermistor to the thermistor cサッカー賭け アプリnectiサッカー賭け アプリ pin (TH pin).
Either a 100kΩ or 470kΩ NTC thermistor can be used.
