Forward and Reverse Switching control mode A or B pairs Q2 and Q3, or Q1 and Q4, respectively, while reversing the supply current to the motor for each switching. When Q2 and Q3 are in use, B-OUT and A-OUT are High level and Low level, respectively. In this case, current flows B-OUT motor A-OUT, causing forward operation as described in the table below. When Q1 and Q4 are in use, current flows in the reverse direction to the above flow, causing reverse motor operation. 2. Brake Control mode C operates Q3 and Q4 while stopping Q1 and Q3. Since A-OUT and B-OUT are held at Low level, both poles of the motor are short-circuited and the motor is stopped. 3. Stand-by Control mode D turns Q1 to Q4 OFF and the motor has no current flow. In this mode, the power current is less than 100 A.

In this case, connect a resistor of at least 1 k in series with the input pins to prevent passage of a large current. 5 MB3863 s TYPICAL CHARACTERISTIC CURVES Supply Voltage vs. Supply Current 80 Output voltage: V OH, V OL(V) Supply current: I CC(mA) Output Current vs. Output Voltage 2.0 1.5 1.0 0.5 V OL 0 40 0 100 200 300 400 500 V OH(V CC-V OH) 60 40 20 V INA = + 2.4 V, V INB = + 0.4 V 0 0 5 10 15 20 25 30 Supply voltage: V CC(V) 35 V INA-V INB = 2.4 V(At braking) Output current: I O(mA) Input Voltage vs. Input Current 700 V CC = +3.5 V 600 Input current I IH(mA) Input Voltage vs. Input Current 10 V CC = +38 V 8 6 4 2 0 0 500 Input current: I IH(A) 400 300 200 100 0 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 Input voltage: V IN(V) 5 10 15 20 25 30 35 Input voltage: V IN(V) 40 45 Supply Current vs. Output Current 100 80 Supply current: I CC(mA) V CC = +36 V V CC = +24 V 60 40 V CC = +7 V V CC = +4 V 20 0 0 0.2 0.4 0.6 0.8 1.0 Output current: I O (mA) 1.2 Note: The above characteristic curves are at Ta = +25C 6 MB3863 s POWER DERATING CHARACTERISTICS (1) ZIP-17P 8 6 (1) Allowable loss P D (W) (2) 4 (3) (4) 2 0 25 50 Ambient temperature T A (C) 75 100 (2) SOP-20P 8 Conditions of heat sink: (1) With 50-cm square and 2-mm thickness plate (2) With 25-cm square and 2-mm thickness plate (3) With 10-cm square and 2-mm thickness plate (4) Without heat sink Allowable loss P D (W) 6 4 2 0 25 50 Ambient temperature T A (C) 75 100 Conditions of heat sink: Without heat sink plate 7 MB3863 s PACKAGE DIMENSIONS Plastic ZIP 17 pin , (ZIP-17P-M03) 23.60(.929)MAX 22.200.20(.874.008) O3.400.20 (.134.008) 3.30(.130)MAX 0.600.10 (.024.004) R3.20(.126) INDEX 11.000.20 (.433.008) 15.00.030 (.591.012) 17.500.30 (.689.012) 21.500.70 (.846.028) 0.600.10 (.024.004) 1.27.013 (.050.005) LEAD No. 1 0.60.010 (.024.004) 17 4.000.40 (.157.016) 3.500.20 (.138.008) 4.00.020 (.157.008) (BOTTOM VIEW) Dimensions in mm mm (inches) Dimensions in (inches) (Continued) 8 MB3863 (Continued) Plastic ZIP 20 pin , (ZIP-20P-M01) 25.88 -0.30 1.019 -.012 +0.20 +.008 2.850.20 (.112.008) INDEX 6.600.25 (.260.010) 7.930.33 (.312.013) 0.250.05 (.010.002) 3.00(.118)MIN 1.27(.050)TYP LEAD No. 1 0.500.10(.020.004) 2.54(.100)TYP (BOTTOM VIEW) 20 C 1994 FUJITSU LIMITED Z20001S-4C-2 Dimensions in mm (inches) 9 MB3863 FUJITSU LIMITED For further information please contact: Japan FUJITSU LIMITED Corporate Global Business Support Division Electronic Devices KAWASAKI PLANT, 4-1-1, Kamikodanaka Nakahara-ku, Kawasaki-shi Kanagawa 211-8588, Japan Tel: (044) 754-3763 Fax: (044) 754-3329 All Rights Reserved.
