2 / 5 page 34 SI-7115B s External dimensions (Unit: mm) Application Note s Determining the output current Io (motor coil current) The output current Io can be set to any value by connecting an external resistor RX across pin 3 and all of pins 2, 4 and 5. Fig. A, B and C show the relationship between the external resistor and the output current, the supply voltage and the output current, and the output current and the temperature, respectively. Output current IO Output current IO RX 0.31 to 0.39 (A/ø) 200 ( Ω) 0.95 to 1.05 (A/ø) 1.4 (k Ω) Condition VCC = 24V, Ta = 25 °C 2-phase excitation Holding mode Motor: 23PM-C109 Fig. A SI-7115B External resistor vs. Output current Fig. B SI-711B Supply voltage vs. Output current Fig. C SI-7511B Output current vs. Temperature Dimensions of SI-7115B pins 11.5±1 4 Plastic package 71.7±0.5 60.3±0.4 Type No. Lot No. 43.2 P=2.54 0.5 3.4 9.0±0.6 Aluminum plate 12 3 18 φ 03 4 1.5 1.0 0.5 0 External resistor Rx (k Ω) VCC Rt Motor : 23PM-C109 24(V) 3.6( Ω) 0 2022 242628 30 0 0.5 1.0 1.5 Supply voltage VCC (V) 100 Ω 300 Ω 600 Ω 1k Ω 2k Ω Rx Motor : 23PM-C109 3.9k Ω 0 100 80 60 40 20 0 0.5 1.0 1.5 Case (aluminium base plate) temperature Tc (°C) Motor : 103G-775-1240 VCC = 24V RX = 1.4k Ω RX = 560 Ω |
