Application information
Figure 7.
Typical application circuit for DC to 10 KHz PWM operation
Note:
1
Reverse battery protection: series relay in VCC line: Rgnd=0 Ohms; series fuse in VCC line
with antiparallel diode between ground and VCC: Rgnd=10 Ohms.
2
Layout hints: the connection between GND pin of the VN670SP and the Power MOSFET
SOURCE connections should be kept short enough to ensure that the dynamic difference
between these two points never exceed 1V for the bridge to operate properly.
