Allegro ACS755xCB-050 is a low-power, high-precision DC current sensor that is mainly used in motor control, load detection and management, power supplies and overcurrent fault protection in industrial, automotive, commercial and communications systems.
The ACS755xCB-050 is a fully integrated Hall‑effect linear current sensor that offers high‑voltage isolation (3 kV) and a low‑resistance copper conduction path (100 µΩ) for minimal power loss. It operates from a single +5 V supply, delivers an 18 kHz bandwidth, and provides a ratiometric output proportional to DC current.
The document lists electrical characteristics such as a primary sensed current range of 0‑50 A, supply voltage 4.5‑5.5 V, isolation voltage up to 3 kV, sensitivity of 60 mV/A, and detailed dynamic response parameters. Typical applications include motor control, load detection, power supplies, and over‑current protection.
| Primary Sensed Current (Ip) | 0 – 50 A |
|---|---|
| Supply Voltage (Vec) | 4.5 V – 5.5 V |
| Isolation Voltage (Viso) | 3 kV (1 min) |
The sensor provides 3 kV isolation between pins 1‑3 and 4‑5 for up to one minute.
It operates from a single +5 V supply with a voltage range of 4.5 V to 5.5 V.
