Design a Custom BoardAbout This Component
Automotive-grade (AEC-Q100) ultra-precise power and current monitor with 20-bit delta-sigma ADC for measuring current, voltage, power, energy, and charge across a shunt resistor. Features ±1µV offset voltage, 0.5% power accuracy, I2C interface with 75µs alert response, and wide 85V common-mode range. Ideal for EV battery management, DC/DC converters, and ADAS applications requiring high-resolution multi-range current sensing.
Package: MSOP-10 (P0.5mm) · 10 pins
Why does this need a breakout?
The 0.5mm pin pitch makes hand soldering impractical without specialized equipment, and the tiny 3x3mm footprint cannot connect directly to breadboards. A breakout board brings these pins to standard 0.1-inch spacing, enabling rapid prototyping of analog-to-digital converters, boost controllers, and audio switches without reflow soldering or custom PCBs.
