Overview
Compact battery chargers require overcurrent protection and temperature monitoring to ensure safety.
Furthermore, compact packaging is required to integrate the battery charger into a system. Our 8/16-bit microcontrollers are available in compact packages with as few as 10 pins, making them ideal for these applications.
