| IP103H Voltage and Current Controller * The Main Differences of IP103 and IP103H are Vicm(Input Common Mode Voltage Range) and Vop(Operating Voltage) DESCRIPTION The IP103H is designed to be used in battery chargers with a constant voltage and a constant current control. This device is a monolithic IC that includes one independent op-amp and other op-amp for which the non inverting input is wired to a 2.5V fixed Voltage reference. Integrating the reference and op-amps creates a solution for low cost charging applications. 8DIP 8SOP FEATURES Operational Amplifiers - Low Supply Current : 200uA/amp - Medium Speed : 1.5MHz - Low Level Output Voltage Close to VEE : 0.1V Typ. -Wide Power Supply Range; 3.6~28V Adjustable Shunt Regulator - Fixed Output Voltage Reference 2.5V - Sink Current Capability : 0.5 to 150mA - 1% Voltage Precision - Latch-up Immunity ORDERING INFORMATION Device IP103H I103H Package 8DIP -40 OC ~ +105O C 8SOP Operating Temp BLOCK DIAGRAM OUT1 1 OP1 VIN1- 2 OP2 VIN1+ 3 Vref 8 VCC 7 OUT2 6 VIN2- VEE 4 5 VIN2+ Dec. 2002 WWW.INTERPIONSEMI.COM -1- IP103H Voltage and Current Controller PIN CONNECTIONS VCC OUT2 VIN2- VIN2+ 8 7 6 5 IP103H IP103 1 OUT1 2 VIN1- 3 VIN1+ 4 VEE PIN DESCRIPTIONS NO 1 2 3 4 5 6 7 8 SYMBOL OUT1 VIN1VIN1+ VEE VIN2+ VIN2OUT2 VCC I/O O I I I I O - DESCRIPTION OP-Amp 1 Output OP-Amp 1 Inverting Input OP-Amp 1 Non-Inverting Input Negative Supply Voltage OP-Amp 2 Non-Inverting Input OP-Amp 2 Inverting Input OP-Amp 2 Output Positive Supply Voltage Dec. 2002 WWW.INTERPIONSEMI.COM -2- IP103H Voltage and Current Controller ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Operating Temperature Storage temperature SYMBOL Vccmax Topr Tstg VALUE 28 -40 ~ +105 -65 ~ 150 UNIT V O C C O ELECTRICAL CHARACTERISTICS Ta = 25O C, VCC = 5V, VEE = GND (unless otherwise specified. ) TOTAL SUPPLY VOLTAGE SECTION CHARACTERISTICS Total Supply Current SYMBOL Icc CONDITIONS Vee = 0V, No Load MIN TYP 0.8 MAX 1.5 UNIT mA Operational Amplifiers Input Offset Voltage Input Bias Current Large Signal Voltage Gain Supply Voltage Rejection Ratio Input Common Mode Voltage Range Common Mode Rejection Ratio Output Source Current Output Sink Current Phase Margin Output Voltage High Output Voltage Low Slew Rate Gain Bandwidth Total Harmonic Distortion Dec. 2002 Vio Iib Avd SVRR Vicm CMRR Isource Isink PM Voh Vol SR GB THD Vcc=15V, Vo=5~10V, Rload =10K Vcc= 5V to 15V Vcc=15V Vo=2.5V, Vid=+1V Vo=2.5V, Vid=-1V Rload=10K,Cload=100pF Vcc=15V, Rload=10K Rload=10K Vi=10V, Vcc=12V, Rload=10K,Cload=100pF Rload=10K,Cload=100pF, f=100kHz 60 65 0 70 3 3 12 1 50 100 100 90 6 6 55 13 100 0.75 1.5 0.05 4.5 150 Vcc1.8V 250 mV nA dB dB V dB mA mA Degree V mV V/us MHz % -3- WWW.INTERPIONSEMI.COM IP103H Voltage and Current Controller ELECTRICAL CHARACTERISTICS Ta = 25O C, VCC = 5V, VEE=GND (unless otherwise specified. ) Adjustable Shunt Regulator CHARACTERISTICS Recommended Cathode Current Reference Input Voltage Reference Input Voltage Deviation Load Regulation Minimum Cathode Current for Regulation SYMBOL Ik Vref dVref Rload Imin Vka=Vref, Ik=10mA -40 OC < Ta <105O C Ik=1mA~10mA CONDITIONS MIN 0.5 2.475 2.5 7 3 0.2 TYP MAX 100 2.525 30 10 0.5 UNIT mA V mV mV mA Dec. 2002 WWW.INTERPIONSEMI.COM -4- MUR120 Vac=85V~265V 4.7uH 1N5819 330uF 10uF 3.3K 4.2V 0.6A Voltage and Current Controller 75K(1%) 2.8K(1%) 6.8K (1%) 47uF IP103H 0.15 1 68K 1.5K PWM CONTROL PC817 0.047uF 8 OP1 2 OP2 1N4148 7 0.1uF 3 Vref 6 470 4 5 1N4148 TYPICAL APPLICATION 1nF 250VAC Dec. 2002 WWW.INTERPIONSEMI.COM 10K (1%) -5- IP103H Voltage and Current Controller ELECTRICAL DIAGRAMS Total Supply Current vs. Supply Voltage 1.0 Supply Current (mA) 0.8 0.6 0.4 0.2 0.0 0 5 10 15 20 25 30 Supply Voltage (V) Fig.1 : Toatal Supply Current vs. Supply Voltage Reference Voltage vs. Temperature 2.510 2.505 Reference Voltage (V) 2.500 2.495 2.490 2.485 2.480 -50 -25 0 25 50 o 75 100 125 Temperature ( C) Fig.2 : Reference Voltage vs. Temperature Dec. 2002 WWW.INTERPIONSEMI.COM -6- IP103H Voltage and Current Controller Minimum Cathode Current vs. Reference Voltage 3.0 2.5 Reference Voltage (V) 2.0 1.5 1.0 0.5 0.0 0 100 200 300 400 500 Cathode Current (uA) Fig.3 : Minimum Cathode Current vs. Reference Voltage Cathode Current vs. Reference Voltage 2.60 Reference Voltage (V) 2.55 2.50 2.45 2.40 0 20 40 60 80 100 Cathode Current (mA) Fig.4 : Cathode Current VS.
