Flyback convertor for driving vacuum fluorescent displays
The new A4401 from Allegro MicroSystems Europe is an automotive-grade quasi-resonant discontinuous flyback convertor control IC which provides all the necessary control functions for driving a vacuum fluorescent display (VFD) with the minimum of external components.
High-performance low-noise current sensors with 2100V RMS isolation
Allegro MicroSystems Europe has introduced two new families of high-performance low-noise Hall-effect current sensors featuring an isolation voltage of 2100 V RMS. Each device is available in ±5 A, ±20 A or ±30 A versions, with corresponding sensitivity levels of 185, 100 or 66 mV/A.
Hall-effect bipolar switch is optimised for pulsed power
The new A1205 from Allegro MicroSystems Europe is a general-purpose Hall-effect bipolar switch that is optimised for applications where pulsing the supply line is used to conserve power. The new device is a next-generation replacement of Allegro's popular A3134 bipolar switch but with enhanced performance in a more compact package. The A1205 is designed to switch in response to a north/south alternating magnetic field, typically from a multi-pole...
Linear Hall-effect sensors have a user-selectable 'sleep' mode
The A139x family of linear Hall effect sensor integrated circuits from Allegro MicroSystems Europe combines micropower operation, a tri-state output and a user-selectable 'sleep' mode. The new sensor ICs provide a voltage output that is directly proportional to an applied magnetic field. The 'sleep' mode allows the devices to operate at a current consumption of less than 25 µA, which contrasts with typical Hall-effect ICs whose sensitivity befor...
Automotive-grade Hall-effect linear current sensors offer high accuracy
The new ACS714 and ACS715 from Allegro MicroSystems Europe are a range of automotive-grade Hall-effect linear current sensors combining high accuracy with excellent voltage isolation. The new devices are designed to provide economical and precise sensing solutions for AC and DC currents in automotive applications such as motor control, load detection and management, switched-mode power supply control, and overcurrent fault protection.
Current sensor features 120 kHz bandwidth, high-voltage isolation and integrated overcurrent detection
The new ACS710 from Allegro MicroSystems Europe is a 120 kHz bandwidth, high-voltage isolation current sensor IC that provides an economical and precise means for current sensing applications in industrial, commercial and communications systems.
Hall-effect switch features low power consumption for battery-operated applications
The new A1171 from Allegro MicroSystems Europe is an ultra-sensitive micropower Hall-effect switch with latched digital outputs and either unipolar or omnipolar actuation. It features operation at low supply currents and voltages, making it ideal for battery-operated applications in portable or handheld communications and computer equipment.
