Introduction
CT455 is a high-bandwidth, low-noise contactless current sensor utilizing Allegro's proprietary XtremeSense tunnel magnetoresistance technology, enabling high-accuracy current measurement for a wide range of consumer, enterprise, and industrial applications. The device supports two standard magnetic field ranges, sensing magnetic fields and converting them to a linear analog output voltage. In addition, CT455 offers a user-programmable version that supports end-of-line calibration of gain and offset. The sensor is preprogrammed to compensate for temperature drift in gain and offset, while the ability to adjust offset and gain relaxes mechanical tolerance requirements during sensor installation. The device output response time is less than 300 ns with a current consumption of approximately 6 mA. CT455 is available in two package options: an eight-pin small outline integrated circuit package and a thin, industry-standard eight-pin thin shrink small outline package. Both are compliant with environmental and RoHS standards.
Features
- User-programmable magnetic field range: 6 to 8 mT, 12 to 48 mT
- Preset magnetic field range: ±6 mT, ±48 mT
- AEC-Q100 Grade 1 automotive certified (Version A only)
- Optimized for high dV/dt applications
- Linear analog output voltage
- 1 MHz bandwidth
- Response time: < 300 ns
- Supply voltage: 3.3 V or 5 V
- Low noise performance
- Package options: 8-pin SOIC, 8-pin TSSOP
Applications
- Solar/Power Inverters
- Battery Management Systems
- Industrial Equipment
- Power Meters
- Power Conditioners
- DC-DC Converters
