(1)Test time should be < 1 ms to minimize temperature change
(2)These parameters are measured with voltage-sensing contacts separate from the current-carrying contacts.
(3)Connect PVDDA2 and PVDDB2 to a 22-V power supply with respect to PVSS. LDROUTA, LDROUTB, BOOTSTRAPA, and BOOTSTRAPB pins
open.
(4)Connect PVDDA2 to 22-V power supply with respect to PVSS. LDROUTA, LDROUTB, BOOTSTRAPA, and BOOTSTRAPB capacitors are
connected, respectively. Clock PWM inputs to allow bootstrap capacitors to charge. 93

99% modulation must be used on PWM_AP, PWM_AM,
PWM_BP, and PWM_BM inputs to prevent the activity detector from shutting down the device during this measurement. Note that FS = 384 kHz.
