APPLICATIONS

Start-Up Conditions

The OM9373 3-phase brushless DC motor controller/

driver is designed to drive fractional to integral

horsepower motors. To ensure proper operation, it is

necessary to ensure that the high-side bootstrap

capcitors are charged during initial start-up. However,

the method(s) used to ensure this may be dependant

upon the application. For example, some applications

may only require that OV_COAST (pin 17) be

connected to ground, either via a hardwire connection

or via a switch (Enable/Disable), before applying Vcc.

When Vcc is applied, the controller/driver is forced

into brake mode for approximately 200µs (all high-

side drivers are disabled and all low-side drivers are

enabled).

This may not be adequate for other applications;

while maintaining a constant speed command,(above

zero),the RC_BRAKE (pin 16) may have to be

momentarily connected to ground via a switch,

either manually or electronically (ref. Figure 1).

Note that with the component values shown in

Figure 1, RC_BRAKE is pulled for low for approximately

300ms after applying Vcc at pin 1.
