STK4172II
Sample Application Circuit (II) (protection circuit and muting circuit)
Thermal Design
The IC power dissipation of the STK4172II at the IC-operated mode is 55W max. at load resistance 8Ω and 91W max. at
load resistance 4Ω (simultaneous drive of 2 channels) for continuous sine wave as shown in Figure 1 and 2.
