Analog Devices MAX14663
The MAX14663 is a complete power solution for portable medical devices, including blood glucose meters. The device integrates a high-efficiency single-cell Li-ion switching charger targeted at space-limited portable applications with small batteries. This mode extends battery shelf life, and enables improved customer experience with immediate out-of-box use.GENERAL DESCRIPTION
An ultra low-power seal mode which significantly reduces standby current and preserves battery charge during prolonged periods of storage is also included. Additionally, the MAX14663 embeds a Maxim proprietary ModelGaugeTM (fuel gauge), which provides an accurate estimate of the available capacity for rechargeable Li-ion batteries. A boost converter and LED current sinks are also integrated for powering OLED displays or LED backlights. Internal cable-detection circuitry enables the MAX14663 to identify the presence of an unpowered/unconnected USB cable. This information can be used by the portable system to intelligently select its operating mode, maximizing accuracy and minimizing measurement errors. The MAX14663 operates over the -20°C to +70°C temperature range and is available in a (5mm x 5mm), 40-pin, TQFN-EP package.APPLICATIONS
