描述

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.

An ultra low-power seal mode which significantly reduces standby current and preserves battery charge during prolonged periods of storage is also included. This mode extends battery shelf life, and enables improved customer experience with immediate out-of-box use.

Additionally, the MAX14663 embeds a Maxim proprietary ModelGauge™ (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.
