NPM1100-EK

The nPM1100 Evaluation Kit (EK) is a tool for evaluating the nPM1100 Power Management IC and evaluate its features for your application. The kit features switches for all selectable settings, buttons to enter and exit ship mode and connectors for batteries, USB and headers for all pins on the PMIC.

The EK allows for testing of the nPM1100 PMICs capabilities with existing applications without the need for creating custom hardware. The board supports charging batteries and powering applications with the included headers and battery connectors.

The kit further includes buttons to enter and exit the PMICs ship mode together with DIP-switches for all configuration options such as selecting the charger's termination voltage, regulated output voltage, charge current and VBUS current limit, and fixing the buck regulator mode to PWM mode only for cleaner operation. The kit also includes indicator LEDs for charge and error indication.
