MAX77786EVKIT#

MAX77786EVKIT# MAX77786 evaluation kit (EV kit) is fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77786 single-cell lithium-ion battery charger. The MAX77786 is for 1S Li+ battery applications and can operate with a 4.7V to 18.2V input voltage with a maximum charging current up to 5.5A. The MAX77786 IC offers a reverse boost as well as fully integrated low-power loss switches to provide small solution size and high efficiency. The EV kit demonstrates the performance of the MAX77786 charger and provides the convenience of evaluating full USB Type-C® power-delivery (PD) solutions with the MAX77958 USB Type-C PD controller. This combination allows fast charging of the battery through the USB Type-C port as well as reverse powering the USB Type-C port with battery on-the-go (OTG) mode. A Micro-B USB cable is included in the EV kit to serve as the interface from a USB port on a Windows® PC to the subordinate I2C port on the MAX77786.

• High-efficiency single-cell switching charger, 90% buck efficiency at 4A/15V input
• Reverse boost with programmable output-voltage options up to 10.805V
• Charge-status output for LED, push-button input for exiting from ship mode
• Dedicated input for suspend mode (SUSPND)
• USB Type-C version 1.3- and PD 3.0-compliant, sink/source/DRP port support
• Programmable power supply (PPS) sink support
• Fast role-swap initial sink support
• Integrated VCONN switch with overcurrent protection (OCP)
• Support Try.Snk state, programmable unplug detection
• Battery charging 1.2 (BC1.2) legacy charger detection
