Figure 32. The TPA3001D1 Output Voltage and Current Waveforms Into an Inductive Load
MAXIMUM ALLOWABLE OUTPUT POWER (SAFE OPERATING AREA)
The TPA3001D1 can drive load impedances as low as 3.6 Ω from power supply voltages ranging from 8 V to
18 V. To prevent device failure, however, the output power of the TPA3001D1 must be limited. Figure 33 shows
the maximum allowable output power versus load impedance for three power-supply voltages at an ambient
temperature of 25°C. (For ambient temperatures of 45°C and 60°C, see Figure 3 and Figure 4.)
