Design a Custom BoardAbout This Component
Linear charger IC for 1- to 4-cell supercapacitors with 800-mA maximum charge current and input voltage tolerance to 40V. Features programmable charge voltage and current via external resistors, integrated thermal regulation, and comprehensive fault protection including overvoltage, overcurrent, and short-circuit detection. Ideal for space-constrained applications like smart meters, barcode scanners, and portable medical equipment.
Package: DFN-8 (2×2mm) · 8 pins
Why does this need a breakout?
Hand-soldering 0.5mm pitch pads is extremely difficult without specialized equipment, and the exposed leads cannot access a breadboard. A breakout board with standard 0.1" headers lets you prototype high-voltage DC-DC converters like the MAX15062 without requiring reflow soldering or custom PCBs, making rapid iteration practical for industrial and sensor applications.
