PRODUCTION DATA
The device works well when powering from a 12-V bus with single VIN configuration. As a single VIN configuration, the internal LDO is powered by a 12-V bus and generates a 3.0-V output to bias the internal analog circuitry and also powers up the gate drives. The VIN input range under this configuration is 4 V to 16 V for up to 20-A load current. Figure 7-5 shows an example for this single VIN configuration.
VIN and EN are the two signals to enable the part. For start-up sequence, any sequence between the VIN and EN signals can power the device up correctly.
