High efficiency switching-type motor driver
BP5801
The BP5801 is an output-variable type 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
efficiency 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.
Applications
Refrigerator,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 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) This can be used as the output-variable type DC / DC converter as well.
6) Space-saving package of SIP.
