Description
This board is a simple carrier of Allegro’s bidirectional ±2.5A ACS724LLCTR-2P5AB Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version accepts a bidirectional current input with a magnitude up to 2.5 A and outputs a proportional analog voltage (800 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
Specifications:
- Current sense: 0.800 V/A
- Minimum logic voltage: 4.5 V
- Maximum logic voltage: 5.5 V
- Supply current: 14 mA
- Version: -2.5A to +2.5A (bidirectional 2.5A)
- Current sensor: Allegro ACS724LLCTR-2P5AB
