UNISONIC TECHNOLOGIES CO., LTD L8001 Preliminary CMOS IC FET BIAS CONTROLLER DESCRIPTION The UTC L8001 is specially designed integrated circuit for satellite receiver front-end block. It provides stable drain and gate bias conditions for GaAs or HEMT FETs. The UTC L8001, provide six FETs bias control respectively. By adjusting two external resistors, it can change the FET’s bias current to optimize the satellite receiver front end block performances. It generates the required negative voltage to bias the gate of GaAs FET, and internally provides protection circuit that can protect the FET devices during supply voltage transient. So it is very popular in satellite receiver front end block. FEATURES * Built in FET device protection circuit * Adjustable FET device operating current * Stable bias control for GaAs and HEMT FETs * Drive up to six FETs * Wide supply voltage range ORDERING INFORMATION Ordering Number Lead Free L8001L-R20-T L8001L-R20-R Halogen Free L8001G-R20-T L8001G-R20-R Package Packing SSOP-20 SSOP-20 Tube Tape Reel L8001L-R20-T (1)Packing Type (1) T: Tube, R: Tape Reel (2)Package Type (2) SSOP-20 (3)Halogen Free (3) L: Lead Free, G: Halogen Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-938.a L8001 Preliminary CMOS IC PIN CONFIGURATION VD1 1 20 VCC VG1 2 19 VD4 VD2 3 18 VG4 VG2 4 17 VD5 VD3 5 16 VG5 VG3 6 15 VD6 GND 7 14 VG6 NC 8 13 RCAL2 CNB1 9 12 RCAL1 CNB2 10 11 CSUB PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 PIN NAME VD1 VG1 VD2 VG2 VG3 VD3 GND NC CNB1 CNB2 CSUB RCAL1 RCAL2 VG6 VD6 VG5 VD5 VG4 VD4 VCC DESCRIPTION 1st Drain output voltage 1st Gate output voltage 2nd Drain output voltage 2nd Gate output voltage 3rd Gate output voltage 3rd Drain output voltage Ground No connect OSC output Rectifier Input Negative voltage output VD1/VD2/VD3 current set resistor connect VD4/VD5/VD6 current set resistor connect 6th Gate output voltage 6th Drain output voltage 5th Gate output voltage 5th Drain output voltage 4th Gate output voltage 4th Drain output voltage Supply voltage UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-938.a L8001 Preliminary CMOS IC BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 5 QW-R502-938.a L8001 Preliminary CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.6~8 V Supply Current ICC 100 mA Maximum Drain Current 15 mA Maximum CSUB Sink Current -500 uA Operating Temperature TOPR -40~80 °C Storage Temperature TSTG -50~150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
