ADVANCE INFORMATION
The device works well when powering from a 12V bus with a single VIN configuration. As a single VIN configuration, the internal LDO is powered by the 12V bus and generates 4.5V output to bias the internal analog circuitry and also powers up the gate drives. The VIN input range under this configuration is 4V to 18V. Figure 6-5 shows an example for this single VIN configuration.
VIN and CNTL are the two signals to enable the part. For start-up sequence, any sequence between the VIN and CNTL signals can power the device up correctly.
