Allegro MicroSystems introduced a new customer programmable, Hall effect-based current sensor IC. The A1369 is packaged in a thin 3-pin SIP package to allow for easy integration with a magnetic core to create a highly accurate current sensing module.
The programmable nature of the device enables it to account for manufacturing tolerances in the final current sensing module assembly. These modules can be used in a variety of applications including electric power distribution and solar and wind power applications.
This temperature-stable device is available in a through-hole single in-line package (TO-92). The accuracy of the device is enhanced via 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 device.
The A1369 features one-time programming using non-volatile memory, to store the desired sensitivity and QVO for a given application or circuit. Allegro programs the sensitivity temperature coefficient and QVO temperature coefficient during end-of-line testing to simplify programming requirements for the customer.
This ratiometric Hall effect sensor IC provides a voltage output that is proportional to the applied magnetic field. The quiescent voltage output is user adjustable around 50% of the supply voltage and the output sensitivity is programmable within a range of 8,5 mV/G to 12,5 mV/G for the A1369-10 and 22 mV/G to 26 mV/G for the A1369-24.
The features of this linear device make it ideal for use in industrial applications requiring high accuracy, and are guaranteed over a wide temperature range of –40°C to +85°C.
