VCC Under voltage Protection Operating/Recovery Voltage (U-phase low side)

Note: Sweeps the VCC pin voltage from 15 V and monitors the U pin voltage. The VCC pin voltage when

output is off defines the under-voltage protection operating voltage. Also sweeps from 6 V to increase.

The VCC pin voltage when output is on defines the under voltage protection recovery voltage.

VBS Under-voltage Protection Operating/Recovery Voltage (U-phase high side)

Note: Sweeps the BSU pin voltage from 15 V to decrease and monitors the VBB pin voltage. The BSU pin

voltage when output is off defines the under voltage protection operating voltage. Also sweeps the

BSU pin voltage from 6V to increase and change the HU pin voltage at 5V → 0V→ 5V each time. It

repeats similarly output is on. The BSU pin voltage when output is on defines the under voltage

protection recovery voltage.
