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.

(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
Electrical characteristic curves
Application example
(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.
