ACS758LCB-050U-PFF-T
Overview
The ACS758LCB-050U-PFF-T is a high-accuracy, unidirectional Hall-effect based linear current sensor IC designed to measure up to 50A DC. It features a monolithic Hall IC coupled with an integrated low-resistance copper conduction path, providing 100 micro-ohm typical internal resistance for low power loss. This AEC-Q100 qualified sensor provides 3000V RMS galvanic isolation and a ratiometric analog output proportional to the sensed current.
Why Choose This Part
This sensor offers a 120kHz bandwidth and a fast 4 microsecond response time, making it suitable for high-speed switching applications. Its integrated shield significantly reduces capacitive coupling from the current conductor to the die, ensuring stable performance in high-voltage transient environments. The factory-trimmed gain and offset provide a low total output error of plus or minus 2 percent over the full operating temperature range.
Applications
Key Specifications
Getting Started
To integrate this sensor, connect the high-current path to the PFF-formed leads and provide a 3V to 5.5V supply to the VCC pin. Use an RC filter on the analog output pin to reduce high-frequency noise if the full 120kHz bandwidth is not required for your application. Ensure the PCB layout includes sufficient copper area around the high-current terminals to manage thermal dissipation at continuous 50A loads.
