Reversible Motor Drivers for Brush Motors

0.5A or Less Reversible

Motor Drivers (Single Moter)

No.11008EBT05

BH6578FVM,BD7931F

●Description

The BH6578FVM and BD7931F are reversible motor drivers with a wide output dynamic range, with power MOS used for the

output transistor. The motor drivers can set the output mode to four modes of normal rotation, reverse rotation, stop (idling),

and braking in accordance with input logic (2 inputs).

●Features

1) Wide dynamic range loading driver with MOS output, Ron = 1.0Ω (Top+Bottom)

2) With loading driver voltage setting terminal

3) Built-in thermal shutdown circuit (TSD)

4) MSOP8 package (BH6578FVM)

5) SOP8 package (BD7931F)

●Applications

Tray loading of CD/DVD, applications using DC motors

●Absolute maximum ratings (Ta=25℃)
