Application Information

  1. MUTE,REF & SW45 Function 2. TSD Function
  • When the chip temperature reaches to 167 °C by abnormal condition, the TSD circuit is activated
  • During TSD Function is activated, OP-AMP Output (pin 6) remains below 0.5V . (TSD monitoring function).
  • This makes the bias current of the output drivers shut down, and all the output drivers are on cut-off state. Therefore the chip temperature begins to decrease.
  • When the chip temperature falls to 63 °C, the TSD circuit is deactivated and the output drivers start to operate normally. 3. Notice
  • If REF1(pin1) or REF2(pin25) is lower than 0.7V , BTL Output is off.
  • Under V oltage Protecton Function. ( If SVcc is lower than 3.8V , Chip is disable. Hysterisis is 0.2V)
  • Mute ON BTL OutPut V oltage is as followed: - Mute ON BTL Output (CH1,2) = (PVcc1 ) / 2 - Mute ON BTL Output (CH3,4) = ((PVcc2-0.6) / 2
  • Each output to output and output to GND short should be kept away.
