8 / 68 page  TAS5731M SLOS838B – JULY 2013 – REVISED NOVEMBER 2013 www.ti.com PIN FUNCTIONS (continued) PIN 5-V TYPE(1) TERMINATION(2) DESCRIPTION TOLERANT NAME NO. VREG 31 P Digital regulator output. Not to be used for powering external circuitry. PowerPAD™ P Provides both electrical and thermal connection from the device to the board. A matching ground pad must be provided on the PCB and the device connected to it via solder. For proper electrical operation, this ground pad must be connected to the system ground ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT DVDD, AVDD –0.3 to 4.2 V Supply voltage PVDD_x –0.3 to 30 V 3.3-V digital input –0.5 to DVDD + 0.5 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) OUT_x to PGND_x 32(4) V BST_x to PGND_x 39(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 Maximum 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 Operating Conditions is 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 V. (4) DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions. THERMAL INFORMATION TAS5731M THERMAL METRIC(1) UNIT PHP (48 PINS) θJA Junction-to-ambient thermal resistance 27.9 °C/W θJB Junction-to-board thermal resistance 13 °C/W θJC(bottom) Junction-to-case (bottom) thermal resistance 1.1 °C/W θJC(top) Junction-to-case (top) thermal resistance 20.7 °C/W ψJT Junction-to-top characterization parameter 0.3 °C/W ψJB Junction-to-board characterization parameter 6.7 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 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 26.4(1) 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 (1) For operation at PVDD_x levels greater than 18V, the modulation limit must be set to 93.8% via the control port register 0x10. 8 Copyright © 2013, Texas Instruments Incorporated Product Folder Links :TAS5731M |
