Points to Notice for Terminal Description and PCB Layout (1) IN1, IN2/ H Bridge Control Terminal It decides output logic for H bridge. Input Output IN1 IN2 OUT1 OUT2 L L OPEN OPEN H L H L L H L H H H L L State STOP FORWARD REVERSE BRAKE (2) TEST/ Terminal for Testing This is the terminal used at the time of distribution test. Please connect to GND. Please be careful because there is a possibility of malfunction if it is not connected to GND. (3) VCC/ Power Supply Terminal Motor’s drive current is flowing in it, so please connect it in such a way that the wire is thick & short and has low impedance. VCC voltage may have great fluctuation, so please connect the bypass capacitor (100uF to 470uF) as close as possible to the terminal. Adjust in such a way that the VCC voltage is stable. Please increase the capacitance if needed, especially when large current or motors that have great back electromotive force are used. In addition, to reduce the power supply’s impedance in wide frequency bandwidth, parallel connection of multi-layered ceramic capacitor (0.01µF to 0.1µF) is recommended. Extreme care must be observed to make sure that the VCC voltage does not exceed the rating even for a moment. Moreover, there is a built-in clamp component in the output terminal to prevent electrostatic destruction. If sudden pulse or surge voltage of more than the maximum absolute rating is applied, the clamp component operates which can result to destruction. Please be sure to not exceed the maximum absolute rating. It is effective to mount a Zener diode with maximum absolute rating. Also, diode is inserted between VCC terminal and GND terminal to prevent electrostatic destruction. If reverse voltage is applied between VCC terminal and GND terminal, there is a danger of IC destruction so please be careful. (4) GND/ Ground Terminal In order to reduce the noise caused by switching current and to stabilize the internal reference voltage of IC, please connect it in such a way that the wiring impedance from this terminal is made as low as possible to achieve the lowest electrical potential no matter what operating state it may be. (5) OUT1,OUT2/ H Bridge Output Terminal Motor’s drive current is flowing in it, so please connect it in such a way that the wire is thick & short and has low impedance. It is also effective to add a Schottky diode if output has great positive or negative fluctuation when large current is applied. For example, a counter electromotive voltage etc. is great. Moreover, there is a built-in clamp component in the output terminal to prevent electrostatic destruction. If sudden pulse or surge voltage of more than the maximum absolute rating is applied, the clamp component operates which can result to destruction. Please be sure to not exceed the maximum absolute rating. www.rohm.com © 2016 ROHM Co., Ltd. All rights reserved.

When the IC’s chip temperature rises above 175°C (Typ), the motor output becomes OPEN. Also, when the temperature returns to under 150°C (Typ), it automatically returns to normal operation. However, even when TSD is in operation, if heat is continued to be applied externally, heat overdrive can lead to destruction. (7) Over-Current Protection (OCP) This IC has a built in Over-Current Protection circuit as a provision against destruction when the motor outputs are shorted to each other or VCC-motor output or motor output-GND is shorted. This circuit latches the motor output to OPEN condition when the regulated threshold current flows for 4μs (typ). It returns with power reactivation. The over-current protection circuit aims to prevent the destruction of the IC only from abnormal situations such as when motor output is shorted and it is not meant to be used as protection or security for the device. Therefore, the device should not be designed to make use of the function of this circuit. After OCP operation, if abnormal situations continues and returned by power reactivation or reset of the PS terminal happens repeatedly, then OCP operates constantly. The IC may generate heat or otherwise deteriorate. When the L value of the wiring is great due to the long wiring and the over-current flows, the output terminal voltage increases and the absolute maximum values may be exceeded. As a result, there is a possibility of destruction. Also, when a current flows, which is over the output current rating and under the OCP detection current, the IC can heat up to over Tjmax=150°C. This can deteriorate the IC. Therefore, current which exceeds the output rating should not be applied. (8) Under Voltage Lock Out (UVLO) This IC has a built-in Under Voltage Lock Out function to prevent false operation such as IC output during power supply under voltage. When the applied voltage to the VCC terminal goes under 5V (Typ), the motor output is set to OPEN. This switching voltage has a 1V (Typ) hysteresis to prevent false operation by noise etc. (9) Over Voltage Lock Out (OVLO) This IC has a built-in Over Voltage Lock Out function to protect the IC output and the motor during power supply over voltage. When the applied voltage to the VCC terminal goes over 32V (Typ), the motor output is set to OPEN. This switching voltage has a 1V (Typ) hysteresis and a 4μs (Typ) mask time to prevent false operation by noise etc. Although this over voltage locked out circuit is built-in, there is a possibility of destruction if the absolute maximum value for power supply voltage is exceeded. Therefore, the absolute maximum value should not be exceeded. (10) Ghost Supply Prevention (protects against malfunction when power supply is disconnected) If a control signal (IN1, IN2) is applied when there is no power supplied to the IC, there is a function which prevents false operation by voltage applied via the electrostatic destruction prevention diode from the control input terminal to the VCC, to this IC or to another IC’s power supply. Therefore, there is no malfunction in the circuit even when voltage is supplied to these input terminals while there is no power supply. www.rohm.com © 2016 ROHM Co., Ltd. All rights reserved.

Refer to the Power Dissipation curve. Also, we are taking measurements of thermal resistance value θja of the actual boards used. Please feel free to contact our salesman. The calculated values above are only theoretical. For actual thermal design, please perform sufficient thermal evaluation for the application board used, and create the thermal design with enough margin to not exceed Tjmax=150°C. Although not normally used, if the IC is to be used under specific or strict heat conditions, please consider attaching an external Schottky diode between the motor output terminal and GND to decrease heat from the IC. (1) Temperature Monitoring There is a way to directly measure the approximate chip temperature by using the TEST terminal. However, temperature monitor using TEST terminal is only for evaluation and experimenting, and must not be used in actual usage conditions. TEST terminal has a protection diode to prevent electrostatic discharge. The temperature may be monitored using this protection diode. (a) Measure the terminal voltage when a current of IDIODE=50μA flows from the TEST terminal to the GND, without supplying VCC to the IC. This measurement is the VF voltage inside the diode. (b) Measure the temperature characteristics of this terminal voltage. (VF has a linear negative temperature factor against the temperature.) With the results of these temperature characteristics, chip temperature may be calibrated from the TEST terminal voltage. (c) Supply VCC, confirm the TEST terminal voltage while running the motor, and the chip temperature can be approximated from the results of (b).

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the maximum junction temperature rating. 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. www.rohm.com © 2016 ROHM Co., Ltd. All rights reserved.

Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. 11. Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. 12. Regarding the Input Pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. Figure 8. Example of monolithic IC structure 13. Thermal Shutdown Circuit(TSD) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 14. Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. www.rohm.com © 2016 ROHM Co., Ltd. All rights reserved.

Also, the back of board as well as the surfaces has large areas of copper foil heat dissipation patterns, greatly increasing power dissipation. The back metal is shorted with the back side of the IC chip, being a GND potential, therefore there is a possibility for malfunction if it is shorted with any potential other than GND, which should be avoided. Also, it is recommended that the back metal is soldered onto the GND to short. Please note that it has been assumed that this product will be used in the condition of this back metal performed heat dissipation treatment for increasing heat dissipation efficiency. 4.0 Measurement machine：TH156 (Kuwano Electric) Measurement condition：ROHM board Board size：70mm x 70mm x 1.6mm (With through holes on the board) 3.75W 4 Board ①: 1-layer board (Copper foil : 0mm x 0mm) Board ②: 2-layer board (Copper foil : 15mm x 15mm) Board ③: 2-layer board (Copper foil : 70mm x 70mm) Board ④: 4-layer board (Copper foil : 70mm x 70mm) Power Dissipation：Pd[W] 3.0 2.11W Board ①: θja=153.2°C/W Board ②: θja=113.6°C/W Board ③: θja=59.2°C/W Board ④: θja=33.3°C/W 3 2.0 1.10W 2 1.0 0.82W 1 0 25 50 75 85 100 125 150 Ambient Temperature:Ta[°C] Figure 9.
