® MP113 Printhead Driver Module FEATURES 2 Power, Analog Output Channels • High Output Voltage: Up To 135Vpp • High Output Current: 3A Continuous, 7A Peak (Per Channel) • High Output Slew Rate: Up To 45V/μs • 100W Dissipation Capability (Per Channel) • Over-temperature Protection • Temperature Sense Integrated Digital Printing Data Converter • LVDS Serial Data Input, 1- Or 2-bits Per Nozzle • Up To 1024 Nozzles • Output Waveform Frequency: Up To 50kHz APPLICATIONS • Industrial Inkjet Printers DESCRIPTION MP113 is an inkjet printhead driver intended for use with Fujifilm Dimatix SG-class printheads. It can also be used with Q-class print heads and compatible printheads of other brands. MP113 contains an analog and a digital section. The analog section consists of two independent power amplifiers, each of which capable of producing the fire pulses needed to drive up to 512 inkjet nozzles. The digital section converts 1- or 2-bit, digital printing data into bit streams for the printhead’s output latches, and exactly timed analog input signals for the power op amps. The analog section plugs into the digital section and is built on a thermally conductive but electrically insulating substrate that can be mounted to a heat sink. The digital section has card edge connectors for connection to the printhead(s) and to digital printing control. www.apexanalog.com © Apex Microtechnology Inc.

The 5V supply powers the MP113 and the print-head. The VCC continuous current value does NOT include any current used by the print-head. HIGH VOLTAGE POWER SUPPLY CURRENT USAGE The current draw on the high voltage power supply (+VS) is determined by the output waveform and pulse repeat frequency. Use figure 6 below to gauge the required output current when selecting a power supply. All values below were collected at 25°C, +VS = 160V. The MP113 was connected to an SG1024 print-head with all nozzles switched ON, or full load (CL=150nF). The test waveform was 130V peak at 45 V/us (see figure 5 below). 6 MP113U Rev D ® MP113 Figure 5: Waveform Used for Current Testing 140 120 Volts 100 80 60 40 20 0 0 2 4 6 8 10 12 14 Microseconds Figure 6: Supply Current vs Pulse Repeat Frequency 900 Supply Current (mA) 800 700 600 500 400 300 200 100 0 0 4 8 12 16 20 24 28 32 36 40 44 48 52 Pulse Repeat Frequency (kHz) MP113U Rev D 7 ® MP113 SYSTEM PROTECTION Parameter Temperature Accuracy Test Conditions Min Typ TC=0°C to 85°C1 Thermal System Shut-down Temperature, TSD Thermal System Warning Temperature Thermal Shutdown Temperature, Hysteresis Max Units ±2 °C 85 °C 70 °C 2 °C Notes: 1.
