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.
