Single-Cell Lithium Battery Protection IC from Diodes Incorporated Delivers High-Precision Low-Power Performance

PLANO, Texas — (BUSINESS WIRE) — December 15, 2015 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the AP9101C. This IC provides protection for single-cell lithium-ion (Li+) or lithium-polymer battery packs. The device can turn off external MOSFET switches when detecting over-charge voltage, over-discharge voltage, over-charge current, over-discharge current and other abnormalities. This capability is particularly important in consumer markets for products such as smart phones, cameras and similar portable devices.

High-precision voltage detection over the full -40°C to +85°C temperature range promotes maximum cell lifetime and safe operation during charge and discharge cycles. The AP9101C also features a built-in time delay circuit that allows the various protection functions to be implemented with fewer components and requiring no external capacitors.

The AP9101C provides design flexibility with or without power-down mode and can be quickly customized to protect different cell specifications in various applications. A low quiescent current of 3μA in normal mode, and just 0.1μA when powered down, delivers useful power saving benefits.

The AP9101C is offered with standard SOT25 and SOT26 package options. Further information is available at
