Features, Applications

The is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4- bridge-tied load (BTL) 100 W per channel with low harmonic distortion, low integrated noise, and low idle current. The TAS5342 has a complete protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These protection features are short-circuit protection, over-current protection, under voltage protection, over temperature protection, and a loss of PWM signal (PWM activity detector). A power-on-reset (POR) circuit is used to eliminate power-supply sequencing that is required for most power-stage designs.

Protection modes are selected by shorting M1, M2, and M3 to VREG or GND.

Description All protection systems enabled Latching shudown on, PWM activity detector and OLP disabled All protection systems enabled All protection systems enabled All protection systems enabled (3) Latching shudown on, PWM activity detector and OLP disabled (3) Reserved

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. 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. PPSC detection system disabled.

PARAMETER RJC (C/W)--2 BTL 4 SE channels RJC (C/W)--1 BTL 2 SE channel(s) RJC (C/W)--1 SE channel Power Pad area (1) (2)

JC is junction-to-case, CH is case-to-heatsink. RCH 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 RCH with this condition is 0.6C/W for the DDV package.
