High current active bias controller IC
The company's bias control solutions automatically adjust an amplifier’s gate voltage to achieve a constant bias current over part-to-part and temperature variations. This auto-gate bias adjustment provides a significant advantage compared with discrete-based solutions since it eliminates manual calibration. Additionally, the HMC980 active bias controller die offers a significant PCB area reduction by integrating negative voltage generator, automatic gate adjustment and power-up sequencing circuit blocks in a single monolithic device.
The HMC980 is designed to control amplifiers operating in Class A mode with bias currents up to 1.6 A and supply voltages from 5 V to 16.5 V. The HMC980 active bias controller die occupies less than 3.2 mm2 of circuit area, requires a minimal number of external components, and incorporates an optional current alarm feature.
For applications which require a surface mount compatible solution, the HMC980 is also available in a 4 x 4 mm QFN plastic package as the HMC980LP4E. Both complement the company’s line of DC power management solutions which operate with bias currents up to 2 A and supplies from 3 V to 16.5 V.
Die samples, SMT product samples and evaluation PC boards for all SMT packaged products are available from stock.
