Driver IC for PPC Series

High Performance, High Reliability

50 V 2ch Brush Motor Drivers

for PPC's etc.

BD64220EFV

General Description

BD64220EFV is a built-in 2 channel H bridge motor

driver for 2 DC brush motors or 1 bipolar stepping motor.

This driver can drive high efficiency by direct PWM or

PWM constant current control.

There are built in protection circuits in this IC. It is

possible to output an abnormal detection signal for

Wired-OR that notifies each protection circuit operation,

which contributes to set high reliability.
