LTC4162-L

Demonstration circuit 2038A shows the LTC4162 multicell step-down battery charger with PowerPath^™ and I²C telemetry operating with a configurable chemistry and cell count. The LTC4162 supports up to eight cells for Li-Ion, nine cells for LiFePO₄, and 6V, 12V, 18V, or 24V lead-acid batteries. Programmable and fully autonomous charge algorithms can be chosen for each of the chemistries.

The DC2038A is populated with one of the six adjustable LTC4162 variants, each suited to a specific battery chemistry and default MPPT enabled state. For more information, refer to the DC2038A demo manual.

Demonstration circuit 2654A features the EZ-PD^™ CCG3  USB Type-C Port Controller IC designed by Cypress  Semiconductor. This product is a daughter board meant to interface with some of Analog Devices’ power product demonstration circuits in order to demonstrate their compatibility with the USB Type-C Power Delivery specification.

The default program for this board negotiates a USB Power Delivery profile and chooses the highest voltage advertised by the power adapter plugged into the board, then turns on the power switches to power the main PCB through the banana plugs for a low-impedance connection. Any required digital information is passed between boards through header J3.
