XL2982SL

XL2982SL SOP20 Features and Benefits Simplified Block Diagram ▪ TTL, DTL, PMOS, or CMOS compatible inputs ▪ 500 mA output source current capability ▪ Transient-protected outputs ▪ Output breakdown voltage to 50 V Description Recommended for high-side switching applications that benefit from separate logic and load grounds, these devices encompass load supply voltages to 50 V and output currents to -500 mA. These 8-channel source drivers are useful for interfacing between low-level logic and high-current loads. Typical loads include relays, solenoids, lamps, stepper and/or servo motors, print hammers, and LEDs. A L L OWA B L E P A C K A G E P OW E R DIS S IP A T ION (W) All devices may be used with 5 V logic systems — TTL, Schottky TTL, DTL, and 5 V CMOS. The device packages offered are electrically interchangeable, and will withstand a maximum output off voltage of 50 V, and operate to a minimum of 5 V. All devices in this series integrate input current limiting resistors and output transient suppression diodes, and are activated by an active high input. The package is a 20-pin wide-body SOIC with improved thermal characteristics compared to the 18-pin SOIC version it replaces (100% pin-compatible electrically). The package is lead (Pb) free, with 100% matte-tin leadframe plating. 2.5 2.0 20-LE AD S OIC , R JA = 90 C /W 1.5 1.0 0.5 0 25 50 75 100 125 150 Absolute Maximum Ratings Rating Units Output Voltage Range Characteristic VCE 5 to 50 V Input Voltage VIN 20 V Output Current IOUT –500 mA Package Power Dissipation PD See graph – – Operating Ambient Temperature TA Range S –20 to 85 ºC Maximum Junction Temperature TJ(max) 150 ºC Tstg –55 to 150 ºC Storage Temperature Symbol Notes 1 XL2982SL SOP20 One of Eight Drivers Typical electrosensitive printer application R IN1 1 20 IN2 2 19 IN3 3 18 IN4 4 17 IN5 5 16 IN6 6 15 IN7 7 14 IN 8 8 13 VS 9 12 NC 10 11 R R R R R R R L L L L L L L L NC Pins 10 and 11 can float; other pins match discontinued 18-pin SOIC: 1 to 9 same, pins 12 to 20 match pins 10 to 18 2 XL2982SL SOP20 ELECTRICAL CHARACTERISTICS1,2 at TA = +25°C (unless otherwise specified).

Systems applications well below the specified output loading may require timing considerations for some designs, i.e., multiplexed displays or when used in combination with sink drivers in a totem pole configuration. 3 XL2982SL SOP20 TEST FIGURES Figure 1 Figure 2 VS VS V Figure 3 V V CE I IN mA V mA OPEN I OUT VIN μA IN S V IN I CEX Figure 4 Figure 5 VS VS I S mA OPEN μA OPEN VIN Figure 6 IR OPEN VF VIN 4 V I F XL2982SL SOP20 500 500 450 450 RECOMMENDED MAXIMUM OUTPUT CURRENT 350 3 300 4 5 250 200 NUMBER OF OUTPUTS CONDUCTING SIMULTANEOUSLY 8 7 6 150 100 400 ALLOWABLE PEAK COLLECTOR CURRENT IN mA AT 70°C 400 VS = 15 V RECOMMENDED MAXIMUM OUTPUT CURRENT 350 300 3 4 250 5 200 8 7 6 NUMBER OF OUTPUTS CONDUCTING SIMULTANEOUSLY 150 100 VS = 15 V 50 0 50 0 10 20 30 50 60 40 PER CENT DUTY CYCLE 70 80 90 0 100 10 0 20 30 Input current as a function of input voltage 2.5 2.0 INPUT CURRENT, IIN (mA) ALLOWABLE PEAK COLLECTOR CURRENT IN mA AT 50°C Allowable peak collector current as a function of duty cycle 1.5 UM IM X MA 1.0 AL PIC TY 0.5 2 4 6 8 INPUT VOLTAGE (VOLTS) 5 10 12 50 60 40 PER CENT DUTY CYCLE 70 80 90 100 XL2982SL SOP20 65 6
