Detailed Description
1. Standby Switch (pin 4)
The power supply can be turned on or off via
pin 4 (Stby). The threshold voltage of pin 4 is
set at about 3 VBE (typ.). The power supply
current is about 0.01 μA (typ.) in the standby
state.

Benefits of the Standby Switch
(1)
VCC can be directly turned on or off by a microcontroller, eliminating the need for a switching relay.
(2)
Since the control current is minuscule, a low-current-rated switching relay can be used.

2. Mute Function (pin 22)
The audio mute function 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 value of the external pull-up resistor is determined, based on pop noise value.
For example, when the control voltage is changed from 5 V to 3.3 V, the pull-up resistor should be:
3.3 V / 5 V × 47 kΩ = 31 kΩ

3. AUX Input (pin 25)
The pin 25 is for input terminal of AUX
amplifier.
The total gain is 0dB by using of AUX
amplifier.
Therefore, the μ-COM can directly drive
the AUX amplifier.
BEEP sound or voice synthesizer signal can be
input to pin 25 directly.
When AUX function is not used, this pin must be
connected to PRE-GND (pin 13) via a capacitor.

4. Prevention of speaker damage (in case of a layer short-circuit of the speaker)
When the DC resistance between the OUT+ and OUT− pins falls below 1 Ω, the output current exceeds 4 A.
At this time, the protection circuit is activated to limit the current draw into the speaker.
This feature prevents the speaker from being damaged, as follows:
< Speaker damaging scenario >
A DC current of over 4 V is applied to the speaker due to an external circuit failure (Note 4).
(Abnormal DC output offset)
↓
The speaker impedance becomes 1 Ω or less due to a layer short.
↓
A current of over 4 A flows into the speaker, damaging the speaker.

Note 3: An abnormal DC offset voltage is incurred when the input bias to the power IC is lost due to a leakage
current from a coupling capacitor at the input or a short-circuit between the IN and adjacent lines.

5. Pop Noise Suppression
Since the TB2929HQ uses the AC-GND pin (pin 16) as the common input reference voltage pin for all
amplifiers, the ratio of the input capacitance (C1) to the AC-to-GND capacitance (C6) should be 1:4.
Also, if power is removed before C1 and C6 are completely charged, pop noise will be generated because of
unbalanced DC currents.
To avoid this problem, it is recommended to use a larger capacitor as C2 to increase the charging times of C1
and C6. Note, however, that C2 also affects the time required from power-on to audio output.
The pop noise generated by the muting and unmuting of the audio output varies with the time constant of
C4. A larger capacitance reduces the pop noise, but increases the time from when the mute control signal is
applied to C4 to when the mute function is enabled.

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must
not be exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be
irreparably altered and the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation
in other equipment. Applications using the device should be designed so that no absolute maximum rating
will ever be exceeded under any operating conditions.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set
forth in this document.

• 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 the 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.
