ACS770KCB-150B-PFF-T
Overview
The ACS770KCB-150B-PFF-T is a high-accuracy, 150A bidirectional Hall effect current sensor designed for AC and DC current sensing. It features a low-resistance integrated conductor and a chopper-stabilized BiCMOS Hall IC that provides a ratiometric voltage output proportional to the sensed current. This AEC-Q100 qualified device offers 120kHz bandwidth and digital temperature compensation for stable performance in harsh environments.
Why Choose This Part
The sensor provides high galvanic isolation due to its open-loop Hall architecture, eliminating the need for expensive opto-isolators. Its extremely low internal conductor resistance (typically 100 micro-ohms) minimizes power loss and heat generation, while the factory-trimmed 13.3mV/A sensitivity ensures high accuracy of +/-0.6% across its 150A range.
Applications
Key Specifications
Getting Started
To integrate this sensor, ensure the 5V supply is decoupled with a 0.1uF capacitor placed close to the VCC pin. Connect the PFF-style formed leads to high-current busbars or PCB traces capable of handling 150A, and route the VOUT signal to a high-impedance ADC input on your microcontroller. Calibration for zero-current offset (typically VCC/2 for bidirectional units) should be performed at startup.
