MODE PINS Mode Name PWM Input(1) Description M3 M2 M1 0 0 0 BTL mode 1 2N All protection systems enabled 0 0 1 BTL mode 2 2N Latching shudown on, PWM activity detector and OLP disabled 0 1 0 BTL mode 3 1N All protection systems enabled 0 1 1 PBTL mode 1N / 2N (2) All protection systems enabled 1 0 0 SE mode 1 1N All protection systems enabled(3) 1 0 1 SE mode 2 1N Latching shudown on, PWM activity detector and OLP disabled(3) 1 1 0 Reserved 1 1 1 (1) The 1N and 2N naming convention is used to indicate the number of PWM lines to the power stage per channel in a specific mode. (2) PWM_D is used to select between the 1N and 2N interface in PBTL mode (Low = 1N; High = 2N). PWM_D is internally pulled low in PBTL mode. PWM_A is used as the PWM input in 1N mode and PWM_A and PWM_B are used as inputs for the 2N mode. (3) PPSC detection system disabled. PARAMETER TAS5352DDV RθJC (°C/W)—2 BTL or 4 SE channels 1.3 RθJC (°C/W)—1 BTL or 2 SE channel(s) 2.6 RθJC (°C/W)—1 SE channel 5.0 Power Pad area(2) 36 mm2 (1) JC is junction-to-case, CH is case-to-heatsink. (2) RθCH is an important consideration. Assume a 2-mil thickness of high performance grease with a thermal conductivity at 2.5W/m-K between the pad area and the heat sink. The RθCH with this condition is 0.6°C/W for the DDV package. Copyright © 2007, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s): TAS5352 |
