TECHNICAL NOTE
Motor Driver IC Series for Tape Record Systems
2 in 1 Motor Driver For VTRs
BD6903EFV, BD6904FP
●
Description
The BD6903EFV and BD6904FP single chip 3-phase full-wave motor drivers integrate soft switching for low noise sensorless driving as well
as a PG amplifier that enables PG/FG output, making them ideal for use in cylinder motors and loading motors in non-portable Video Tape
Recorders (VTRs).
●
Features
1) Cylinder motor driver
2) Sensorless 3-phase full-wave soft switching drive system
3) DMOS output
4) Built-in startup circuit
5) Built-in PG amp
6) 3-value common PG/FG output
7) Loading motor driver
8) Three mode output (forward, reverse, brake), depending on control logic input
9) DMOS output
10) Built-in Thermal Shut-Down (TSD) circuit
●
