I. Device Description
A. General
The MAX14676D is a battery charge management solutions ideal for low-power wearable applications. This device includes a linear battery charger
with a smart power selector, ModelGauge™ fuel gauge, and several power optimized peripherals. They feature an ultra-low power buck regulator with
a quiescent current of 900nA (typical) and 74% efficiency with 10µA output. The battery charger features a smart power selector operation allowing
operation with dead battery. It limits input current based on a register setting. If the charger power source is unable to supply the entire system load,
the smart power control circuit will supplement the system load with current from the battery. The MAX14676D embeds a Maxim proprietary
ModelGauge fuel gauge to provide an accurate estimate of the available capacity for rechargeable lithium batteries. The MAX14676D includes a
synchronous high-efficiency step-down converter. The device features a fixed-frequency PWM mode for tighter regulation and a burst mode for
increased efficiency during light-load operation. The MAX14676D has a boost regulator and three programmable current sinks that can be used to
drive a variety of LED configurations. The boost converter is controlled independently from the current sinks, and they can be also used separately.
The MAX14676D features a power switch controller that allows the device to be turned on and off. This controller also provides a delayed reset signal
and voltage sequencing. This device is available in a 42-bump, 0.5mm pitch, 3.497mm x 3.118mm WLP package.
