All of the device's electrical characteristics are warranted when the device is operated within these ranges. Always use semiconductor devices within their recommended operating condition ranges. Operation outside these ranges may adversely affect reliability and could result in device failure. No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet. Users considering application outside the listed conditions are advised to contact their FUJITSU representatives beforehand. 3 MB3863 s ELECTRICAL CHARACTERISTICS (VCC = 24 V, VIN = 2.4 V, Ta = +25 C) Values Unit Min.

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 Q2 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 supply 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. 7 MB3863 s TYPICAL CHARACTERISTIC CURVES Supply Voltage vs. Supply Current 80 Output voltage: V OH, V OL(V) Supply current: I CC(mA) 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 40 0 0 V INA - V INB = 2.4 V(At braking) 2.0 1.5 1.0 0.5 Output Current vs. Output Voltage V OH(V CC - V OH) V OL 100 200 300 400 500 Output current: I O(mA) Input Voltage vs. Input Current 700 V CC = +3.5 V 600 Input current I IH(mA) 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) 8 6 4 2 0 0 10 Input Voltage vs. Input Current V CC = +38 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) 60 40 V CC = +4 V 20 0 0 0.2 0.4 0.6 0.8 1.0 Output current: I O (mA) 1.2 V CC = +36 V V CC = +24 V V CC = +7 V Note : The above characteristic curves are at Ta = +25C 8 MB3863 s POWER DERATING CHARACTERISTICS SOP-20P 8 Allowable loss P D (W) 6 4 2 0 25 50 Ambient temperature Ta (C) 75 100 Conditions of heat sink: Without heat sink plate 9 MB3863 s ORDERING INFORMATION Part number MB3863PF Package 20-pin plastic SOP (FPT-20P-M01) Remarks 10 MB3863 s PACKAGE DIMENSION 20-pin plastic SOP (FPT-20P-M01) *12.70 -0.20 .500 -.008 20 +0.25 +.010 Note 1 : Pins width and pins thickness include plating thickness.
