CN3791 AI Analysis:
Datasheet, Specs, Alternatives & ECAD

Key features include a 4.5V-28V input range, 4A maximum charge current, 300kHz switching frequency, 4.2V constant voltage regulation, and built-in MPPT tracking.

The CN3791 uses a constant voltage method to track the maximum power point of the solar panel. The MPPT pin is modulated to 1.205V, and an external resistor divider sets the target solar panel voltage.

Engineers should keep input/output capacitors and the power MOSFET close to the IC, use short traces for the current sensing resistor, and ensure the ground return path is clean to prevent switching noise.

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: low; readiness: moderate_availability.

Use the CN3791 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about CN3791 pinout to locate pins, power rails, and interface signals before layout.
