The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. The TAS5102/TAS5103 are available in a thermally enhanced package: • TAS5102 Pad Up 32-pin HTSSOP PowerPAD™ package (DAD) • TAS5103 Pad Down 32-pin HTSSOP PowerPAD™ package (DAP) DAD PACKAGE DAP PACKAGE (TOP VIEW) (TOP VIEW) Mode PWM INPUT OUTPUT CONFIGURATION PROTECTION SCHEME M2 M1 0 0 2N (1) AD/BD modulation 2 channels BTL output BTL mode (2) 0 1 1N (1) AD modulation 2 channels BTL output BTL mode (2) Protection works similarly to BTL mode (2). Only 1 0 1N (1) AD modulation 4 channels SE output difference in SE mode is that OUT_X is Hi-Z instead of a pulldown through internal pulldown resistor. 1 1 Reserved (1) The 1N and 2N naming convention is used to indicate the required number of PWM lines to the power stage per channel in a specific mode. (2) An overcurrent protection (OC) occurring on A or B causes all channels to shut down. An OC on C or D works similarly. Global errors like overtemperature error (OTE), undervoltage protection (UVP), and power-on reset (POR) affect all channels. PARAMETER TAS5102DAD TAS5103DAP RθJC (°C/W) 1.69 1.69 RθJA (°C/W) See Note (1) 23.5 (1) The TAS5102 package is thermally enhanced for conductive cooling using an exposed metal pad area. It is impractical to use the device with the pad exposed to ambient air as the only means for heat dissipation for higher power applications. For this reason, RθJA, a system parameter that characterizes the thermal treatment, is provided in the Application Information section of the data sheet. An example and discussion of typical system RθJA values are provided in the Thermal Information section. This example provides additional information regarding the power dissipation ratings. This example should be used as a reference to calculate the heat dissipation ratings for a specific application. TI application engineering provides technical support to design heatsinks if needed. Also, for additional general information on PowerPad packages, see TI document SLMA002B. 2 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TAS5102 TAS5103 |
