AC/DC Open Loop Hall Current Sensor Module CYHCS950

The CYHCS950 series is an open-loop current sensor module based on the Hall effect principle, providing a more economical and accurate solution for AC or DC current sensing in industrial, commercial and communication systems. It can be used for motor control, load detection and load management, power supplies and DC-DC converters, photovoltaic inverters, UPS, overcurrent protection and low and medium power inverter current detection applications. The CYHCS950 consists of a high precision, low noise, low temperature drift linear Hall IC, a magnetic core and a low resistance (0.12mΩ) current conductor path (located near the die surface). The applied current flowing through this conductor path generates a magnetic field, which is converted by the Hall IC into a voltage output proportional to the input current. The CYHCS950 output voltage is provided by a low offset, chopper-stabilized BCD Hall IC that is factory calibrated internally for different current ranges. The output of the chip has a positive slope (>VOQ) as the applied external current flows through the conduction path (from pin 4 to pin 5). The internal resistance of the conduction path is typically 120uΩ, allowing for low power consumption. The terminals of the conduction path (pins 4 and 5) are electrically isolated from the signal terminals (pins 1 to 3). This allows the CYHCS950 current sensor module to be used in current sensing applications without the need for other expensive isolation techniques. All pins of CYHCS950 series are tinned and the package material is lead-free and RoHS compliant.
