ACS770LCB-050B-PFF-T
Overview
The ACS770LCB-050B-PFF-T is a high-accuracy, Hall-effect based linear current sensor IC designed for bidirectional AC or DC current sensing up to 50 A. It features a proprietary integrated shield that greatly reduces capacitive coupling from the current conductor to the die due to high dV/dt signals, providing low-noise performance in high-voltage applications.
Why Choose This Part
The sensor provides 120 kHz bandwidth and utilizes chopper stabilization for superior offset stability across its operating temperature range. Its integrated galvanic isolation allows for high-side current sensing without the need for expensive opto-isolators or complex isolated power supplies.
Applications
Key Specifications
Getting Started
To evaluate this sensor, connect the PFF leadframe to your high-current path and provide a stable 5V VCC supply. The analog output voltage is proportional to the sensed current and can be directly interfaced with a microcontroller ADC after applying a simple RC low-pass filter to manage the 120 kHz bandwidth noise.
