Note2: Since “AC-GND” pin is a common reference voltage for all input, this product needs to set the ratio of an input capacitance (C1) and the AC-GND capacitance (C6) to 1:4 Note3: Use the low leak current capacitor for C1 and C6.
- Mute Function (Pin 22) The audio mute fun ction is enabled by setting pin 22 Low. R1 and C4 determine the time constant of the mute function. The time constant affects pop noise generated when power or the mute function is turned on or off; thus, it must be determined on a per-application basis. (Refer to Figures 3 and 4.) The values of external elements (R1, C4) of this pin have decided them based on 5 V control. In case that it is controlled by other than 5V, please reexamine the value of the external pull-up resistor as follows; For example: When the control voltage is changed from 5V to 3.3V, the pull-up resistor should be: 3.3V/5V×47 kΩ=31kΩ Figure 3 Mute Function Figure 4 Mute attenuation − VMUTE (V) 5 V 10 kΩ Control voltage: VMUTE (V) ATT – VMUTE Mute attenuation ATT (dB)
- Auto Muting Functions The TCB501HQ has two automatic mute functions. a) Low VDD Mute (Automatic mute function) b) Standby Off Mute.
9.1 Low VDD Mute
When the supply voltage became lower than 5.5V ( typ.), The TCB501HQ operates the mute circuit automatically. This function prevents the large audible transient noise which is generated by low VDD.
9.2 Standby-Off Mute
The TCB501HQ operates the mute circuit during the standby-off transition. When the ripple voltage reached V DD/5, the standby -off mute is terminated. Additionally, in the standby -off transition, it is recommended that the external mute has to be ON till the internal mute-OFF, a nd that the timing of the external mute-OFF has to be set after the internal mute-OFF. Note1: Out sound time is changed due to capacity of the C2 capacitor.

9.3 Mute-off after standby-off
The pop noise is generated when the capacitor of ripple, input, and ACGND has not finished to charge fully. Please set “Mute-off” that it is sufficient margin in considering an enough charge time after the middle point potential stable. Figure 5 Mute-off transition after standby-off
- High-side Switch The Q1 (high-side switch) is always turned on during Power-ON. The high-side switch can be used for many application circuits related to Power -ON. This output incorporates the backflow prevention structure. V DD Rsw Figure 6 High-side switch
- Output DC Offset Detection This function detects the offset voltage between OUT (+) and OUT (-). The detection result is gotten by pin1. When the offset voltage appeared by the external parts accident, for example the leak of coupling capacitor, this function can contribute to a part of safety system to prevent the speaker damage. The example flowchart: The safety system to prevent damaging to speakers by abnormal offset. The result of detection does not judge the abnormal offset or not. This function detects only the offset voltage which is decided by specification.
11.1 Operation description of output offset pin
The result of output offset voltage detection of Pin1 is gotten by the internal open -drain transistor which synchronizes with off set voltage. This function is always available. If this pin does not be used, connect to GND or open.

- Low voltage operation The TCB501HQ applies the amplifier circuit to reduce the audible pop noise and sound cutting due to low V DD voltage.
12.1 Operation description
When the headroom voltage is suppressed by the low V DD, the TCB501HQ switches output middle point potential from VDD/2 to V DD/4 and reduces the audible pop noise and the sound cutting. T he behavior of outputs (Vout) and ripple (Vrip) is showed the figure 9 below. (A) VDD > Vth1 Normal operation (B) VDD < Vth1 Switch middle point potential from VDD/2 to Vrip to keep the headroom voltage. (C) VDD < Vth2 The C2 (ripple) is discharged with muting, and amplifier is off. Each of threshold voltage is below. Vrip = 3V (Ripple pin voltage) Vhr1 = 2.2V (typ.), Vhr2 = 1.7V (typ.) Vth1 = Vout+Vhr1 = 2Vrip + Vhr1, Vth2 = Vrip + Vhr2 Figure 9 Output VDD/2 voltage in lowering VDD
- P rotection Functions This product has internal protection circuits such as thermal shut down, over-voltage, short to VDD, short to GND, and out to out short circuit protections. (1) Thermal shut down It operates when junction temperature exceeds 150°C (typ.). When it operates, it is protected in the following order. 1. An Attenuation of an output starts first and the amount of attenuation also increases according to a temperature rising, 2. All outputs become in a mute state, when temperature continues rising in spite of output attenuation. 3. Shutdown function starts, when a temperature rise continu es though all outputs are in a mute state. In any case if temperature falls, it will return to normal operation automatically. (2) Over-voltage It operates when voltage exceeding operating range is supplied to VDD pin. If voltage falls, it will return to normal operation automatically. When it operates, all outputs bias and high-side switch are turned off and all outputs are shut-off. Threshold voltage is 21.5 V(typ.) (3) Short to V DD, Short to GND, Output to output short It operates when each output pin is in irregular connection and the load line goes over the SOA (Safe Operation Area) of power transistor (DMOS). When it operates, all outputs bias circuits are turned off and all outputs are shut -off. If irregular connection is canceled, it will return to normal operation automatically.

If any of these rating would be exceeded during operation, the device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed. Moreover, these operations with exceeded ratings may cause break down, damage, and/or degradation to any other equipment. Applications using the device should be designed such that each maximum rating will never be exceeded in any operating conditions. Before using, creating, and/or producing designs, refer to and comply with the precautions and conditions set forth in this document. Note 4: Package thermal resistance R th(j-t) = 1°C/W (typ.) (Ta = 25°C, with infinite heat sink) Note 5: When the TAB temperature is more than absolute maximum ratings, the thermal shut down system (mute) operates. The threshold TAB temperature is 16 0°C(typ.). The threshold TAB temperature is defined as the highest temperature point of the metal side surface. Regarding heat radiation design, please design the device so that heat is appropriately radiated, not to exceed the specified junction temperature (Tj) at any time and condition.

- Attention in Use
- Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case of over current and/or IC failure. The IC will fully break down when used under conditions that exceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise occurs from the wiring or load, causing a large current to continuously flow and the breakdown can lead smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required.
- If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the design to prevent device malfunction or breakdown caused by the current resulting from t he inrush current at power ON or the negative current resulting from the back electromotive force at power OFF. For details on how to connect a protection circuit such as a current limiting resistor or back electromotive force adsorption diode, refer to individual IC datasheets or the IC databook. IC breakdown may cause injury, smoke or ignition.
- Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable, the protection function may not operate, causing IC breakdown. IC breakdown may cause injury, smoke or ignition.
- Carefully select external components (such as inputs and negative feedback capacitors) and load components (such as speakers), for example, power amp and regulator. If there is a large amount of leakage current such as input or negative feedback condenser, the IC output DC voltage will increase. If this output voltage is connected to a speaker with low input withstand voltage, overcurrent or IC failure can cause smoke or ignition. (The over current can cause smoke or ignition from the IC itself.) In particular, please pay attention when using a Bridge Tied Load (BTL) connection type IC that inputs output DC voltage to a speaker directly.
- Over current Protection Circuit Over current protection circuits (referred to as current limiter circuits) do not necessarily protect ICs under all circumstances. If the Over current protection circuits operate against the over current, clear the over current status immediately. Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can cause the over current protection circuit to not operate properly or IC breakdown before operation. In addition, depending on the method of use and usage conditions, if over current continues to flow for a long time after operation, the IC may generate heat resulting in breakdown.
- Thermal Shutdown Circuit Thermal shutdown circuits do not necessarily protect ICs under all circumstances. If the Thermal shutdown circuits operate against the over temperature, clear the heat generation status immediately. Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can cause the thermal shutdown circuit to not operate properly or IC breakdown before operation.
- Heat Radiation Design When using an IC with large current flow such as power amp, regulator or driver, please design the device so that heat is appropriately radiated, not to exceed the specified junction temperature (Tj) at any time and condition. These ICs generate heat even during normal use. An inadequate IC heat radiation design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown. In addition, please design the device taking into considerate the effect of IC heat radiation with peripheral components.
- Installation to Heat Sink Please install the power IC to the heat sink not to apply excessive mechanical stress to the IC. Excessive mechanical stress can lead to package cracks, resulting in a reduction in reliability or breakdown of internal IC chip. In addition, depending on the IC, the use of silicon rubber may be prohibited. Check whether the use of silicon rubber is prohibited for the IC you intend to use, or not. For details of power IC heat radiation design and heat sink installation, refer to individual technical datasheets or IC databooks.
