For Air-Conditioner Fan Motor
3-Phase Brushless Fan Motor Driver
BM620XFS Evaluation Board
BM620xFS-EVK-001
Introduction
This evaluation board has been developed for ROHM's motor driver customers evaluating BM620XFS series.
This motor driver IC integrates a MOSFET as the output transistor, and put in a small full molding package with
the controller chip and the high voltage gate driver chip. The protection circuits for overcurrent, overheating,
under voltage lock out and the high voltage bootstrap diode with current regulation are built-in.

Operation Procedures
Necessary equipments
・DC power-supply of 18V for VCC/VSP input
・DC power-supply of 400V/4A for VDC input
・3-Phase Brushless Fan Motor
Connecting the equipments(for Hall elements Motor application)
1. DC power-supply preset to 15V(for VCC), 0V(for VSP) , 0V(for VDC) and then the powers output turn off.
2. FG monitor sets the S1 switch, and Motor direction sets the S2 switch.
Don't change S2 switch setting while the Motor is operating.
3. Connect positive-terminal of Hall elements DC power to HBP terminal, and negative-terminal to HBN terminal.
4. Connect positive-terminal of Hall elements U to HUP terminal, and negative-terminal to HUN terminal.
5. Connect positive-terminal of Hall elements V to HVP terminal, and negative-terminal to HVN terminal.
6. Connect positive-terminal of Hall elements W to HWP terminal, and negative-terminal to HWN terminal.
7. Connect U-terminal of Motor to U terminal, and V-terminal to V terminal, W-terminal to W terminal.
8. Turn on DC power-supply outputs. (1.VCC, 2.VSP, 3.VDC)
9. Set voltage for DC power-supply output for VDC.
10. Check Motor operation at VSP>2.1V(typ) starting.
If Motor doesn't operate, Motor terminal connection may be wrong, please set VSP and VDC voltage at 0V.
11. VSP voltage control the rotation speed.
