♦ ♦ ♦ ♦ Small Inductor (3.5µH) Programmable Charge Current > 4.5A Automatic Power-Source Selection Analog Inputs Control Charge Current and Charge Voltage ♦ Monitor Outputs for AC Adapter Current Battery-Discharge Current AC Adapter Presence ♦ Independent 3.3V 20mA Linear Regulator ♦ Up to 17.6V (max) Battery Voltage ♦ +8V to +28V Input Voltage Range ♦ Reverse Adapter Protection ♦ System Short-Circuit Protection ♦ Cycle-by-Cycle Current Limit MAX8730 The MAX8730 reduces charge current to give priority to the system load, effectively limiting the adapter current and reducing the adapter current requirements. The MAX8730 provides a digital output that indicates the presence of an AC adapter, and an analog output that monitors the current drawn from the AC adapter. Based on the presence and absence of the AC adapter, the MAX8730 automatically selects the appropriate source for supplying power to the system by controlling two external switches.
