MAX1773EVKIT

Evaluation Kit for the MAX1773


Please check latest availability status for a specific part variant.

Description

The MAX1773 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that routes charge and discharge currents between two battery packs, a buck step-down Battery Chargers, and an AC-adapter power source. The circuit uses a MAX1773 IC in a 20-pin TSSOP package and is configured for an AC-adapter input range of +4.75VDC to +28VDC.

The EV kit uses seven P-channel MOSFETs to steer current between the power sources and the load. The battery minimum voltage level sets the threshold for battery undervoltage conditions and can be adjusted from +4.65V to +13V.

The EV kit features an SMBus™ signal multiplexer that routes SMBus signals for the smart battery packs. LEDs are provided to indicate the status of the AC adapter and battery packs. The MAX1773 EV kit also demonstrates low-current usage with several options to reduce current usage.
