ACS758LCB-100B-PFF-T

 ACS758LCB-100B-PFF-T : Thermally Enhanced, Fully Integrated, Hall-Effect Based, High Accuracy Linear Current Sensor IC with 100 μΩ Current Conductor The Allegro ACS758 family of current sensor ICs provides an economical and accurate solution for AC or DC current sensing. Typical applications include motor applications, load detection and management, power supplies and DC-DC converter control, inverter control, and overcurrent protection. The device consists of a low-offset, precision linear Hall circuit with a copper current path close to the surface of the die. Current flowing through this current path generates a magnetic field that is converted by the Hall IC into a proportional voltage output. Device accuracy is optimized by placing the magnetic signal close to the Hall sensor. The precise, proportional output voltage is provided by a chopper-stabilized, low-offset BiCMOS Hall IC that is factory programmed for accuracy. Allegro's proprietary integrated shielding technology pro...

VBGL7103: Using the new SGT technology

  With the rise of mobile phone fast charging, electric vehicles, brushless motors and lithium batteries, the demand for medium-voltage MOSFETs is increasing, and medium-voltage power devices are beginning to flourish. Due to its huge market share, many domestic and foreign manufacturers have widely used related devices in motor drive systems, inverter systems and power management systems, and are core power control components. As an important power semiconductor device, SGT MOSFET is widely used in PD fast charging, motor drive (Motor driver), battery management system (BMS), power tools and other fields. Single-tube SGT MOSFET:  VBGL7103   has the advantages of low on-resistance and low gate charge, which can improve power density, reduce losses, and have better EMI advantages.   1. Low on-resistance, effectively reducing losses VBGL7103 adopts a unique SGT (shielded gate trench) process design, which makes the switching loss much smaller than that of ordinary tren...
