Driver meets required qualifications for design-ins for space programs

Microsemi has announced its radiation-tolerant AAHS298B eight-channel source driver for space applications, successfully qualified and certified by the US DLA as QML Class V and Q, with four SMDs listed, is now in production. The device is offered in two package types with various screening options, meeting the key requirements to operate in space environments. “Successfully achieving these qualifications is vital to securing design-ins in satellite programs requiring the highest quality and reliability performance,” said Dorian Johnson, Microsemi’s high-reliability product marketing manager. “Obtaining QML status not only demonstrates Microsemi’s continued commitment to supplying integrated space solutions, but gives our customers the added assurance that our radiation-tolerant AAHS298B source driver can meet the demanding requirements of the DLA while offering the ability to use the device in conjunction with our LX7730 telemetry controller, LX7720 motor controller and LX7710 diode array devices.” “Increasing requirements for higher output currents combined with demands for weight and board space reductions were compelling reasons to initially investigate Microsemi’s AAHS298B source driver for our designs,” said Glenn Lommasson, vice president of Design and Development Engineering Services (DDES) Corp. “Also, the presence of the internal clamp diode in the driver output allowed a much more efficient method for implementing transient protection during inductive kickback events, which reduced the number of clamp diodes needed in other solutions. The recent device qualification and SMD listing as a QML-V device was also a very important element for us to baseline this part as more programs are mandating Technical Operating Report (TOR) guidelines for parts quality, DLA certification and radiation assurance.”
