High efficiency switching-type motor driver

BP5807

The BP5807 is an output-variable type 3-output DC motor driver module. This module can change the output

voltage for driving the DC motor by inputting PWM signal or DC voltage into the control terminal. The power

conversion rate is high, and power saving of the application can be realized, since the input voltage can be

changed into the specified output voltage by the switching system. Further, this module can be used as the

output-variable type DC / DC converter as well.

Applications

Refeigerator, The rotation-control type DC motor driver and the output-variable type DC / DC converter

Features

1) Electrical power loss is small even when there is a difference between the input voltage and motor driving

voltage, since electrical power conversion efficiency is high (90% Typ.) as the switching system is employed

for changing the voltage.

2) Motor driving voltage can be set to any optional value by the output voltage control signal.

3) The control signal corresponds with both PWM signal and DC voltage.

4) The control terminal is easy to be designed, as it is only one-terminal type.

5) The three outputs are independent.

6) This can be used as the output-variable type DC / DC converter as well.

7) Space-saving package of SIP.

Circuit operations

(1) Description

BP5807 is a DC motor driver that can establish any output voltage by inputting PWM signal and DC voltage

into the control pin(6, 7, 8pin).Electrical power loss is small even when there is a difference between

the input voltage and output voltage, since changing from the input voltage into the specified output

voltage can be made by the switching system. This module is most suitable in case that the number of

rotation of the motor is controlled by changing the driving voltage, or in case that the motor of a lower

specified voltage than 14V is driven by the electrical power source of 14V.

(2) Control signals

1) PWM signal : the output voltage will be controlled by that duty. The larger the duty is, the higher the output

voltage will be. It is necessary to be attentive, because the output voltage value changes depending on the

H-level and L-level values of PWM signal as well, at this time.

2) DC voltage : the output voltage will be controlled by that voltage value. The higher the voltage, the

higher the output voltage will be.

(3) The two outputs are independent. It is possible to control each output independently with a different kind of

the control signal (PWM signal or DC voltage).

Operation notes

(1) The output current should be reduced according to an increase in the output voltage or ambient

temperature. Use the module within the derating curve range.

(2) The protection circuit for output current is not incorporated. Be sure to take safety measures such as

fusing if short-circuit loads or overcurrent is probable.

(3) External capacitor

Since the switching system is employed for the purpose of changing the voltage, ripple current flows to the

capacitor to be added to pins 1, 4, 11, 13, 14, 17. Select the product of which allowable ripple current is

more than this value.
