8 / 75 page  TAS5715 SLOS645 – AUGUST 2010 www.ti.com ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT DVDD, AVDD –0.3 to 3.6 V Supply voltage PVDD_x –0.3 to 30 V 3.3-V digital input –0.5 to DVDD + 0.5 V Input voltage 5-V tolerant(2) digital input (except MCLK) –0.5 to DVDD + 2.5(3) V 5-V tolerant MCLK input –0.5 to AVDD + 2.5(3) V OUT_x to PGND_x 32(4) V BST_x to PGND_x 43(4) V Input clamp current, IIK ±20 mA Output clamp current, IOK ±20 mA Operating free-air temperature 0 to 85 °C Operating junction temperature range 0 to 150 °C Storage temperature range, Tstg –40 to 125 °C (1) Stresses beyond those listed under absolute ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operation conditions are not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability. (2) 5-V tolerant inputs are PDN, RESET, SCLK, LRCLK, MCLK, SDIN, SDA, and SCL. (3) Maximum pin voltage should not exceed 6.0V (4) DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions. DISSIPATION RATINGS (1) DERATING FACTOR TA ≤ 25°C TA = 45°C TA = 70°C PACKAGE ABOVE TA = 25°C POWER RATING POWER RATING POWER RATING 7-mm × 7-mm HTQFP 20 mW/°C 2 W 1.6 W 1.1 W (1) This data was taken using 1 oz trace and copper pad that is soldered directly to a JEDEC standard high-k PCB. The thermal pad must be soldered to a thermal land on the printed-circuit board. See TI Technical Briefs SLMA002 for more information about using the HTQFP thermal pad RECOMMENDED OPERATING CONDITIONS MIN NOM MAX UNIT Digital/analog supply voltage DVDD, AVDD 3 3.3 3.6 V Half-bridge supply voltage PVDD_x 8 26 V VIH High-level input voltage 5-V tolerant 2 V VIL Low-level input voltage 5-V tolerant 0.8 V TA Operating ambient temperature range 0 85 °C TJ (1) Operating junction temperature range 0 125 °C RL (BTL) Load impedance Output filter: L = 15 mH, C = 680 nF. 4 8 Ω Minimum output inductance under 10 LO (BTL) Output-filter inductance mH short-circuit condition (1) Continuous operation above the recommended junction temperature may result in reduced reliability and/or lifetime of the device.
