EXT INDUCTIVE LOAD DRIVER — Bifilar (unipolar) INCANDESCENT LAMP DRIVER — High stepper motors can be driven directly. The internal kickback incandescent lamp turn-on/inrush current can destroy diodes prevent damage to the output transistors by semiconductor lamp drivers and contributes to poor lamp suppressing the high-voltage spikes which occur when reliability. However, lamps with steady state current ratings turning OFF an inductive load. up to 600 mA can be driven with the UDN2549B without the need for warming or current limiting resistors. FAULT CONDITIONS — In the event of a shorted load, shorted winding, or stalled motor, the load current will When an incandescent lamp is initially turned ON, the attempt to increase. As described above, the drive current to cold lamp filament is at minimum resistance and would the output stage is diverted (limiting the load current to about normally allow a 10x to 12x inrush current. With the 1 A), causing the output stage to go linear. As the junction UDN2549B, the high inrush current is sensed by an internal temperature of the output stage increases, the thermal limit sense resistor. The load current is limited to approximately circuit will become operational, further decreasing the drive 1 A by the shunting transistor sensing the output current current. The load current (junction temperature) is then a through the sense resistor. During this short transition period, function of ambient temperature, state of remaining drivers, the output driver is driven in a linear fashion. As the lamp supply voltage, and load resistance. If the fault condition is warms up, the filament resistance increases to its maximum corrected, the output driver will return to its normal saturated value. The output driver then goes into saturation and applies condition. Short circuit protection is provided for each the full supply voltage to the lamp. However, inrush currents output for supply voltages up to 25 V. of 1 A or more will force the driver into foldback current limiting. To avoid this problem, a warming or current limiting resistors should be used in the lamp circuitry. 4 For Ordering Information, Call: 1-800-322-3616 or 1-256-880-0444 • FAX (256) 882-0859 ✄ VMIVME-2128 ✪✄✰✮✄✯❊❘�✄✬❙◗❚❊❘ VMIVME-2128 Electrical Specifications Per Output Channel 1.
