The Allegro family of current sensor IC linear devices are customer programmable for both offset and sensitivity. The temperature coefficient of both sensitivity and zero gauss offset voltage are factory trimmed to maintain an accurate output voltage over temperature. These Hall linear ICs are packaged in a 1 mm thick KT package SIP that is often used in applications with a ferromagnetic core and are designed to sense currents above 1500 A.
The A1360 family of high bandwidth and fast response time analog output sensors are suitable for HEV inverter applications or wherever >200 A continuous currents need to be sensed in high frequency switching applications. In lower frequency applications, the output can be filtered to improve output resolution. A lower frequency device with a digital PWM output is also available and is suitable for 60 Hz applications.
