The FDSL006LF is a dual-mode Hall effect current sensor with both open loop and closed loop operation with optimized sensitivity in a small package. It provides more accurate, reliable current measurement capability when compared to traditional Hall effect linear current sensors. The sensor operates on a supply voltage of 4.5V-13V, making it an ideal choice for applications that require high accuracy and maximum reliability.

The main application field of the FDSL006LF is low-current sensing for motor control, automation systems, industrial applications, and consumer electronic equipment. It is widely used in power tools, cordless drills, electric scooters, and robotics. The sensor has two operating modes, open loop and closed loop, enabling it to provide accurate current measurements over a wide range of conditions.

The FDSL006LF works on the principle of magnetoresistive sensing. An internal magnet generates a magnetic field and the Hall element inside the package converts this magnetic field into an electrical signal. The output of the Hall element is amplified and linearized with the use of special algorithms and resistance elements. The resulting output is a signal proportional to the current flowing through the sensor.

The open loop mode of the sensor is designed to detect and measure very low currents, such as those found in current-sensing applications. The accuracy of this mode is limited by environmental effects such as temperature and EQ changes. In the closed loop mode, the sensor measures the current flowing through it with high accuracy, even in varying environmental conditions. This is done by using a temperature-compensated high-precision hybrid amplifier to adjust the output signal based on a reference value set by the user.

The FDSL006LF is a highly reliable, accurate, and compact single package Hall effect current sensor suitable for a wide range of current detection applications. Its dualmode operation and integrated temperature compensation make it an ideal choice for applications that require high accuracy current sensing and maximum reliability.
