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.
