GaN and SiC power devices are expected to rapidly gain market share in electric vehicle and green energy applications. Allegro''s isolated gate driver solutions use a single, small-footprint package that integrates an isolated gate driver, an isolated power supply, and associated passive components. This significantly reduces system design time and complexity and makes it possible for designers to take advantage of the full efficiency benefits that WBG switches provide. Additionally, the reduced system design time and complexity help alleviate the need for additional engineering and design resource
The AHV85110 isolated gate driver is optimized for driving GaNFETs in multiple applications and topologies. An isolated output bias supply is integrated into the driver device, eliminating the need for any external gate drive auxiliary bias supply or high-side bootstrap. This greatly simplifies the system design and reduces EMI through reduced total common-mode (CM) capacitance. It also allows the driving of a floating switch in any location in a switching power topology.
The ACS37610 provides a highly accurate method of measuring 100A to 5000A flowing through a busbar or a PCB without needing a concentrator core or a U-Shaped Magnetic Shield reducing system complexity, bill of material (BOM), cost, footprint, and weight. The differential measurement provides excellent immunity to stray magnetic fields without the need for a magnetic shield that often slows down the response time and adds non-linearity error.
The Allegro ACS711 provides economical and precise solutions for AC or DC current sensing in 100+ V audio, communications systems, clean energy, personal mobility and white goods. The device package allows for easy implementation by the customer.
The device consists of a linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer.
The Allegro ACS724 family of current sensor ICs are economical and precise solutions for AC or DC current sensing in industrial, automotive, consumer, and communications systems. They are offered in multiple compact packages with a high level of integration that fits various application needs.
When you need to add AC power monitoring or DC power monitoring to your device, our ACS37800 power monitoring IC simplifies your task tremendously. Our integrated current sensor technology at the core of this device leverages the Hall effect and galvanic isolation to deliver reinforced isolation without extra board space. When powered from the same supply as the microcontroller unit, multiple power supplies and digital isolation ICs are not needed, which reduces the size of your printed circuit board (PCB). The sensing scheme-isolated current is measured by two Hall plates that deferentially sense the magnetic field of the integrated conductor-eliminates
