Allegro MicroSystems expands isolated gate driver portfolio with bipolar-output power-thru IC

January 21, 2024

Allegro MicroSystems has announced the launch of its second product in the High Voltage Power portfolio, the AHV85111 isolated gate-driver IC.

This new product is designed to simplify the design of high-power energy conversion systems for e-Mobility and clean energy applications, including OBC/DCDC, solar inverter, and datacenter power supply.

The AHV85111 builds on Allegro’s existing power-thru technology, offering a streamlined and safe solution for designers. The gate driver features bipolar-output, which eliminates the need to design a complicated negative isolated DC power supply and removes unnecessary external components, thereby improving time to market. The AHV85111 also includes safety features designed to protect against high operating temperatures in electric powertrain systems and noisy environments in microinverters, datacenter power supplies, or on-board chargers for electric vehicles.

The AHV85111 gate driver offers the benefits of Allegro’s power-thru technology, including 10x lower common-mode capacitance, a 50% smaller footprint, 10x noise reduction, and a 50% efficiency improvement compared to competitor offerings. It also provides overtemperature protection, further enhancing system robustness.
