These 48V products are intended to address the need for flexible and reliable solutions in electric vehicles. Allegro’s new suite of fully integrated gate drivers offer optimised architecture and performance directly impacting vehicle weight, battery/fuel efficiency, and driver safety.
These gate drivers are able to address any load configuration from half bridge with independent high-side and low-side outputs to three-phase brushless DC (BLDC) control. Developed on a high-voltage process node for 48V systems, these devices offer ASIL diagnostics and diagnostic verification enabled with a fully compliant ISO 26262 process.
The new devices include:
- AMT49100 / AMT49101 safety-enhanced three-phase gate drivers for electric power steering and other safety-critical systems
- AMT49502 safety half-bridge gate driver with actuators and solid-state relays
- A89503 safety half-bridge gate driver with independent high-side and low-side output loads for floating loads, such as seat heaters and catalytic heaters
- A89500 100V high-power half-bridge gate driver in DFN package for distributed systems, 48V power inverters, golf carts, and e-bikes
Offered in ultra-small packages, these devices are designed to meet the demands of the automotive market by increasing functionality while decreasing PCB footprint.
