HMC980 is an active bias controller that can automatically adjust the gate voltage of an external amplifier to achieve constant bias current. With an integrated controller, HMC980 achieves safe power on/ off, disable/enable and automatic supply sequencing ensuring the safety of the external amplifier. It can be used to bias any enhancement and depletion type.
• Automatic Gate voltage adjustment (No Calibration required)
• Supply Voltage (5V to 16.5V)
• Bias both Enhancement or Depletion type
devices
• Adjustable Drain Current up to 1.6 A
• Sink or source gate current
• Internal negative voltage generation
• Can be disabled to use external negative rail
• Fast Enable/Disable
• Trigger-out Output for Daisy Chain
• Power-Up and Power-Down Sequencing
• Over/Under Current Alarm with built-in hystresis
• Die Size: 1.4 x 2.26 x 0.25mm
