Typ. Max. MB3863 ■ OPERATIONS 1. 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 µA.

In this case, connect a resistor of at least 1 kΩ in series with the input pins to prevent passage of a large current. 7 MB3863 ■ TYPICAL CHARACTERISTIC CURVES Output Current vs. Output Voltage Supply Voltage vs. Supply Current 2.0 Output voltage: V OH, V OL(V) Supply current: I CC(mA) 80 60 V INA − V INB = 2.4 V(At braking) 40 20 1.5 ∆V OH(V CC − V OH) 1.0 0.5 V INA = + 2.4 V, V INB = + 0.4 V V OL 0 0 0 5 10 15 20 25 30 Supply voltage: V CC(V) 35 40 0 Input Voltage vs. Input Current 400 500 Input Voltage vs. Input Current V CC = +3.5 V V CC = +38 V 8 Input current I IH(mA) 500 Input current: I IH(µA) 300 10 600 400 6 4 300 2 200 0 0 100 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) Supply Current vs. Output Current 100 V CC = +36 V 80 Supply current: I CC(mA) 200 Output current: I O(mA) 700 V CC = +24 V 60 V CC = +7 V 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 Note : The above characteristic curves are at Ta = +25°C 8 100 5 10 15 20 25 30 35 Input voltage: V IN(V) 40 45 MB3863 ■ POWER DERATING CHARACTERISTICS SOP-20P Allowable loss P D (W) 8 6 4 2 0 25 50 Ambient temperature Ta (˚C) 75 100 Conditions of heat sink: Without heat sink plate 9 MB3863 ■ ORDERING INFORMATION Part number MB3863PF 10 Package 20-pin plastic SOP (FPT-20P-M01) Remarks MB3863 ■ PACKAGE DIMENSION 20-pin plastic SOP (FPT-20P-M01) Note 1 : Pins width and pins thickness include plating thickness.
