ACTIVE BIAS CONTROLLER Pin Descriptions
(Continued) Pin Number Function Description Interface Schematic 1.5V reference voltage. 0.1uF or greater capacitor to GND 13 VREF is needed for noise filtering. Bias supply for negative voltage generator. Connect supply 14 Vdd2 voltage with appropriate filtering. Vdd2 supply voltage should be same as Vdd1. 13 T Negative voltage generator charge pump output. Negative voltage generator needs a flying capacitor, a reservoir M 15 CPOUT capacitor and two diodes to operate. Please refer to the application schematic for more info. T - S N E 16 DGND Digital ground domain (DGND). M 11, 17 AGND Analog ground domain (GND). E G A N Feedback (Control) pin for Negative Voltage Genera- A tor Charge Pump. Float to activate the negative voltage 18 VNEGFB generator / Sort to GND to disable the negative voltage generator. R M E Negative input to the chip. Should be supplied with CPOUT W when negative voltage generator is enabled, or connect to O 19 VNEGIN external VSS when negative voltage generator is enabled. For detailed usage please refer to the “Negative Voltage Generator” section. C P D Control pin for VGATEFB. Float VGATEFB when a depletion mode transistor is biased. Selects the mode of 20 VGATEFB operation along with VNEGFB pin. For detailed usage please refer to the Table 1. Mode Selection.
