Detailed Description

Ultra-compact high-side current monitor with zero-drift architecture and ±0.03% accuracy. Operates from 1.8 V to 5.5 V supply. Designed to sense high-side shunt voltage and provide a precise analog output proportional to current. Packaged in a tiny 4-ball DSBGA (approx 1 mm x 1 mm) for space-constrained designs. Industrial temperature range -40°C to 125°C. RoHS3 compliant. Ideal for precision power monitoring in portable and high-density electronics.

Key Features
