The Allegro™ ACS73369 is a customer-programmable, high accuracy linear Hall-effect-based current sensor IC. It is packaged in a thin 3-pin SIP to allow for easy integration with a magnetic core to create a highly accurate current sensing module. The programmable nature of the ACS73369 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 style). The accuracy of the device is enhanced via programmability on the output pin for endof-line optimization without the added complexity and cost of a fully programmable device. The device features One-Time-Programming (OTP)—using nonvolatile memory—to optimize device sensitivity and the quiescent output voltage (QVO) (output with no magnetic field) for a given application or circuit. The ACS73369 also allows 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 sensor ICs 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 9 to 13.5 mV/G for the ACS73369EUAA‑010B5‑C.
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.
