Stepping Motor Driver series
BD6383EFV, BD6385EFV, BD6387EFV, BD6389FM
Description BD6387EFV, BD6385EFV, BD6383EFV, BD6389FM are the high-grade type that provides the highest function and highest reliance in the ROHM stepping motor driver series. This series has the perfect various protection circuits and reduces IC’s generation of heat by adopting low-ON resistance DMOS and high heat-radiation power package. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply’s rated voltage of 36V and rated output current of 1.0A2.2A. For the input interface, the CLK-IN drive mode and the parallel IN drive mode are compatible with each other, so please choose an input mode according to needs of application. There are excitation modes of FULL STEP & HALF STEP (2 kinds), QUARTER STEP mode, and for current decay mode, the ratio of FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized. In addition, being able to drive with one system of power supply makes contribution to the set design’s getting easy.

Power dissipation HTSSOP-B40 Package (BD6387EFV/BD6385EFV/BD6383EFV)
HTSSOP-B40 has exposed metal on the back, and it is possible to dissipate heat from a t hrough h ole in the back. A lso, the back of board as well as the surfaces has large areas of copper foil he at 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.

HSOP-M36 Package (BD6389FM/BD6388FM)
HSOP-M36 has a heat-dissipating FIN terminal on the IC side, but it is possible to greatly increase power dissipation by taking a large heat dissipation pattern, such as with copper foil, on the back as well as the surface of the board. Also, this terminal is a GND potential, therefore there is a possibility for malfunction or destruction if it is shorted with any potential other than GND.

Usage Notes (1) Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaki ng mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses.
(2) Connecting the power supply connector backward
Connecting of the power supply in reverse polarity can da mage IC. Take precautions when connecting the power supply lines. An external direction diode can be added.
(3) Power supply Lines
Design PCB layout pattern to provide low impedance GND and supply lin es . To obtain a low noise ground and supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply terminals to ICs, connect a capacitor between the power supply and the GND terminal. When applying electrolytic capacitors in the circuit, not that capacitance characteristic values are reduced at low temperatures.
(4) GND Potential
The potential of GND pin must be minimum potential in all operating conditions.
(5) Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. Users should be aware that BD6387EFV, BD6385EFV and BD6383EFV have been designed to expose their frames at the back of the package, and should be used with suitable heat dissipation treatment in t his area to improve dissipation. As large a dissipation pattern should be taken as possible, not only on the front of the baseboard but also on th e back surface. BD6389FM and BD6388FM are both equipped with FIN heat diss ipation terminals, but dissipation efficiency can be improved by applying heat dissipation treatment in this area. It is important to consider actual usage conditions and to take as large a dissipation pattern as possible.
(6) Inter-pin shorts and mounting errors
When attaching to a printed circuit board, pay close attention to the direction of the IC and displacement. Improper attachment may lead to destruction of the IC. There is also possibility of destruction from short circuits which can be caused by foreign matter entering between outputs or an output and the power supply or GND.

(7) Operation in a strong electric field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction.
(8) ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.
(9) Thermal shutdown circuit
The IC has a built-in thermal shutdown circuit (TSD circuit). If the chip temperature becomes Tjmax=150, and higher, coil output to the motor will be open. The TSD circuit is designed only to shut the IC off to prevent runaway thermal operation. It is not designed to protect or indemnify peripheral equipment. Do not use the TSD function to protect peripheral equipment.

(10) Inspection of the application board
During inspection of the application board, if a capacitor is connected to a pin with low impedance there is a possibility that it could cause stress to the IC, therefore an electrical discharge should be perform ed after each process. Also, as a measure again electrostatic discharge, it should be earthed during the assembly process and special care should be taken during transport or storage. Furthermore, when connecting to the jig during the inspection process, the power supply should first be turned off and then removed before the inspection.
(11) Input terminal of IC
This IC is a monolithic IC, and between each element there is a P+ isolation for element partition and a P substrate. This P layer and each element’s N layer make up the P-N junction, and various parasitic elements are made up. For example, when the resistance and transistor are connected to the terminal as shown in figure 4,
When GND(Terminal A) at the resistance and GND(Terminal B) at the transistor (NPN),
the P-N junction operates as a parasitic diode.
Also, when GND(Terminal B) at the transistor (NPN)
The parasitic NPN transistor operates with the N layers of other elements close to the aforementioned
parasitic diode. Because of the IC’s structure, the creation of parasitic elements is inevitable from the electrical potential relationship. T he operation of parasitic elements causes interference in circuit operation, and can lead to malfunction and destruction. Therefore, be careful not to use it in a way which causes the parasitic elements to opera te, such as by applying voltage that is lower than the GND (P substrate) to the input terminal.

(12) Ground Wiring Patterns
When using both small signal and large current GND patterns, it is recommended to isolate the t wo ground patterns, placing a single ground point at the application's reference point so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to chang e the GND wiring pattern potential of any external components, either.

Be sure to connect TEST pin to GND.
