Customer-Programmable Current-Sensor IC In Inline Package

News

The new A1369 from Allegro MicroSystems Europe is a customer-programmable, high-accuracy linear Hall-effect-based current sensor IC packaged in a slimline 3-pin single-inline package which allows for easy integration with a magnetic core to create a highly accurate current sensing module.

The A1369 is designed for use with customer-provided steel or other ferromagnetic cores, where its programmable nature allows it to compensate for manufacturing tolerances in the final current sensing module assembly. The accuracy of the device is enhanced by the programmability of both the sensitivity and the quiescent output voltage (QVO − the output with no magnetic field present) on the output pin for end-of-line optimisation without the added complexity and cost of a fully programmable sensor.

The device features one-time programming using non-volatile memory to store the desired sensitivity and QVO for a given application or circuit.
