Half-bridge gate driver eases motor drive design – EDN

Alpha & Omega’s AOZ9530QV half-bridge energy stage lets designers alter gate drive sink/supply present to attenuate EMI and maximize energy effectivity. A part of the corporate’s Good Motor Module household, the machine simplifies single- and three-phase BLDC motor drives in purposes starting from PC and server followers to house home equipment and energy instruments.

Housed in a thermally enhanced 18-pin QFN bundle, the AOZ9530QV packs one half-bridge gate driver able to driving high-side and low-side N-channel MOSFETs. The Good Motor Module additionally integrates a linear LDO regulator and helps 100% PWM obligation operation. Working over an ambient temperature vary of -40°C to +125°C, the AOZ9530QV accepts an enter voltage vary of 10 V to twenty-eight V and offers most output present of seven A.

“We designed the AOZ9530QV in a compact 3×3-mm QFN bundle to fulfill larger density, space-constrained design traits in BLDC motor drives. In a number of cooling fan purposes, the PCB for drive circuitry is enclosed inside the fan meeting. The AOZ9530QV permits shrinking of the PCB enabling a system designer to extend the scale of the fan blades, thus pushing extra air inside a given type issue,” mentioned Armin Hsu, energy IC senior advertising supervisor at AOS.

The AOZ9530QV prices $1 every in plenty of 1000 models. It’s out there in manufacturing portions with a lead time of 24 weeks.
