說明
The MAX14676/MAX14676A are battery-charge-management solutions ideal for low-power wearable applications. These devices include 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 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 MAX14676/MAX14676A embed a Maxim proprietary ModelGauge fuel gauge to provide an accurate estimate of the available capacity for rechargeable lithium batteries.
The MAX14676/MAX14676A include 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 MAX14676/MAX14676A have 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 MAX14676/MAX14676A feature a power switch controller that allows the device to be turned on and off by a pushbutton. This controller also provides a delayed reset signal and voltage sequencing.
These devices are available in a 42-bump, 0.5mm pitch, 3.497mm x 3.118mm wafer-level package (WLP).
