MIC23099 Click carries the MIC23099, a single AA/AAA cell step-down/step-up regulator with battery monitoring. The Click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over the following pins on the mikroBUS™ line: CS, INT.

MIC23099 Click has three screw terminals (Buck 1V, GND and Boost 3V3) which are outputs for connecting some external consumer. The low-battery level is indicated by an onboard STAT LED.

Note: The MIC23099 is not a battery charger and it needs a battery to work properly. The battery is not included.

MIC23099 FEATURES

The MIC23099 is a high-efficiency, low-noise, dual output, integrated power management solution for single-cell alkaline or NiMH battery applications. To minimize switching artifacts in the audio band, both the converters are designed to operate with a minimum switching frequency of 80 kHz for the buck and 100 kHz for the boost. The high-current boost has a maximum switching frequency of 1 MHz, minimizing the solution footprint. The MIC23099 incorporates both battery management functions and fault protection.
