audio application considerations (continued)
reconstruction output filter
An output reconstruction filter is required between the H-bridge outputs and the loudspeaker load. This second
order low-pass filter passes the audio information to the loudspeaker, while filtering out the high frequency
out-of-band information contained in the H-bridge output PWM pulses. The values of the L and C components
selected are dependent on the loudspeaker load impedance. See application note SLAA117.
fault indicator usage
The TAS5100A is a self-protecting device that provides device fault reporting, including over-temperature
protect, under-voltage lockout (low-regulator voltage), and short circuit protection. The short circuit protection
protects against short circuits that may occur at the loudspeaker load when configured according to the
application note SLAA117. The TAS5100A is not recommended for driving loads less than 4
, since the internal
current limit protection might be activated.
An under-voltage lockout signal occurs when an insufficient voltage level is present on the LDROUTA or
LDROUTB pins. During this condition gate drive levels are not sufficient for driving the power MOSFETs. Normal
operation is resumed when the minimum proper LDROUTA or LDROUTB level is obtained, and the low regulator
voltage protect signal is de-asserted. See the control/sense circuitry section for error and warning conditions.
A high temperature warning signal is asserted on pin ERR0 when the device temperature exceeds 130
°C
typical.
If the internal device temperature exceeds 150
°C typical, the over temperature protect signal is asserted and
the TAS5100A is shut down. The device re-enables once the temperature drops to 130
°C typical. See the
control/sense circuitry section for error and warning conditions.
Detection of an illegal PWM input state or the loss of a clocking PWM input signal causes an illegal PWM input
state signal to be asserted on the ERR1and ERR0 pins and sets the SHUTDOWN pin to the low state.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application
Report (literature number SLMA002), for more information on the PowerPAD package. The
thermal data was measured on a PCB layout based on the information in the section entitled Texas
Instruments Recommended Board for PowerPAD
of the before mentioned document. Data in
table is for specified layout. Under other conditions the thermal performance may vary. See Texas
Instruments document SLAA117 for more detailed application information.
