USB host port. The ADP5061 has three factory programmable digital The ADP5061 operates from a 4 V to 6.7 V input voltage range input/output pins that provide maximum flexibility for different but is tolerant of voltages up to 20 V. The 20 V voltage tolerance systems. These digital input/output pins permit combinations of alleviates the concerns about the USB bus spiking during dis- features such as, input current limits, charging enable and connect or connect scenarios. disable, charging current limits, and a dedicated interrupt output pin. The ADP5061 features an internal FET between the linear charger output and the battery. This permits battery isolation and, hence, system powering under a dead battery or no battery scenario, which allows for immediate system function on connec- tion to a USB power supply. Rev.
