NOTES:

1. Test time should be < 1 ms to avoid 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 Fswitching = 384 kHz.
