Introduction
The Allegro ACS37612 current sensor IC enables low-cost solutions for AC and DC current sensing without the need for an external field concentrator core or shield. It is designed for applications where hundreds of amps flow through a busbar or PCB. Current flowing through a busbar or PCB trace generates a magnetic field that is sensed by the monolithic, low-offset, linear Hall IC. The differential sensing topology virtually eliminates all types of errors due to common-mode stray magnetic fields. High isolation is achieved via the no-contact nature of this simple assembly. The ACS37612 is offered in 120 kHz and 240 kHz bandwidth options, making it ideal for inverter phase current sensing, load detection and management, power supplies, and DC/DC converters where fast switching is required. The fast response time enables overcurrent fault detection in safety-critical applications. A -40℃ to 150℃ ambient operating temperature range and a stellar ESD rating make it ready for harsh automotive environments. The ACS37612 is suitable for space-constrained applications because of its low-profile 8-pin surface mount TSSOP package (thin-shrink small outline package, suffix LU) that is lead (Pb) free, with 100% matte tin leadframe plating.
Features
- Eliminates need for concentrator core or shield
- Suited for applications where current flows through busbar or PCB
- Very wide sensing range (2.5 to 20 mV/G)
- Ideal for sensing currents from <200 A to >1000 A
- Factory-programmed segmented linear temperature compensation (TC) provides low thermal drift
- Sensitivity ±1% (typ)
- Offset ±3 mV (typ)
- Differential Hall sensing rejects common-mode magnetic fields
- High operating bandwidth: DC to 240 kHz
- AEC-Q100 Grade 0, automotive qualified
- Contactless, lossless, non-invasive current sensing
- Very fast response time <2 μs (typ)
- 3.3 or 5.0 V single supply operation
- Ratiometric output with unidirectional and bidirectional modes
- Immune to mechanical stress
- Monolithic Hall IC for high reliability
- Wide ambient temperature range: -40℃ to 150℃
- Surface mount, small footprint, low-profile TSSOP8 package
Applications
