The Allegro™ A1369 is a customer programmable, high accuracy linear Hall effect-based current sensor IC. It 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 A1369 enables it to account for manufacturing tolerances in the final current sensing module assembly.
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 on the output pin for end-of-line optimization without the added complexity and cost of a fully programmable device. The device features One-Time-Programming (OTP), using non-volatile memory, to optimize device sensitivity and the quiescent output voltage (QVO) (output with no magnetic field) for a given application or circuit. The A1369 also allow for optimized performance over temperature through programming the temperature coefficient for both Sensitivity and QVO at Allegro end-of-line test.
These ratiometric Hall effect sensors provide 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 makes it ideal for use in industrial applications requiring high accuracy and are guaranteed over a wide temperature range, –40°C to+85°C.
