MAX14663 Portable Medical Power Management Solution with Cable Detection General Description Benefits and Features The MAX14663 is a complete power solution for portable High-Efficiency Switching Charger Tailored for Small medical devices, including blood glucose meters. Capacity Batteries Saves Space, Extends Battery Life The device integrates a high-efficiency single-cell Li-ion Battery Isolation Switch Extends Battery Shelf Life switching charger targeted at space-limited portable Hardware/Software Configurable applications with small batteries. Integrated Power-Key Monitor An ultra low-power seal mode which significantly reduces Integration Simplifies and Shrinks Display Driving standby current and preserves battery charge during Circuitry prolonged periods of storage is also included. This mode 3-Channel Programmable-LED Current Sinks extends battery shelf life, and enables improved customer Integrated Step-Up Converter experience with immediate out-of-box use. Integrated Protection and Control for Reliable Additionally, the MAX14663 embeds a Maxim proprietary Performance TM Fully Integrated Cable Detection Controller to ModelGauge (fuel gauge), which provides an accurate Ensure Measurement Accuracy estimate of the available capacity for rechargeable Li-ion Overvoltage and Thermal Protection batteries. 28V Tolerant VB Input Connection A boost converter and LED current sinks are also integrat- High ESD Protection (VB, DP, DM, KIN) ed for powering OLED displays or LED backlights. 15kV HBM ESD Protection Internal cable-detection circuitry enables the MAX14663 10kV Air-Gap Protection to identify the presence of an unpowered/unconnected 8kV Contact Discharge Protection USB cable. This information can be used by the portable Manual Reset Controller system to intelligently select its operating mode, maximizing 2 Programmable Interrupt Generation (I C) accuracy and minimizing measurement errors. Integrated ModelGauge Host-Side Fuel Gauge Saves The MAX14663 operates over the -20C to +70C Space and Accurately Estimates State of Charge temperature range and is available in a (5mm x 5mm), ModelGauge Algorithm 40-pin, TQFN-EP package. Tolerates Temperature & Load Variation No Error Accumulation Applications Learning Not Necessary Portable Blood Glucose Meters Current-Sense Resistor Not Required Portable Medical Devices USB Connected Devices Ordering Information appears at end of data sheet.
