RECOMMENDED OPERATING CONDITIONS
Digital supply (1)
DVDD
Supply for internal gate drive and logic
GVDD
regulators
PVDD_x
Half-bridge supply
T J
Junction temperature
(1) It is recommended for DVDD to be connected to DREG via a 100-Ω resistor.
ELECTRICAL CHARACTERISTICS
PVDD_X = 23 V, GVDD = 23 V, DVDD = 3.3 V, DVDD connected to DREG via a 100-Ω resistor, R L = 6 Ω, 8X f s = 384 kHz, unless otherwise
noted. AC performance is recorded as a chipset with TAS5010 as the PWM processor and TAS5122 as the power stage.
