SS49E
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the SS49E family does
The SS39ET/SS49E/SS59ET Series are linear Hall-effect sensor ICs available in SOT-23, TO-92-style, and SOT-89B packages. They operate on a supply voltage of 2.7 Vdc to 6.5 Vdc with typical current consumption of 6 mA at 5 Vdc. These devices feature a sensitivity of 1.4 mV/Gauss and an operating temperature range from -40 °C to 100 °C. The integrated circuitry provides low noise output, eliminating the need for external filtering. They are designed for applications requiring basic current sensing, anti-tampering detection, position sensing in e-bikes, magnetic code reading, and speed adjustment triggers in various industrial and medical equipment.
