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.
fault indicator usage
The TAS5110 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. The TAS5110 is not
recommended for driving loads less than 6
,
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 125
°
C
typical.
If the internal device temperature exceeds 150
°
C typical, the over temperature protect signal is asserted and
the TAS5110 is shut down. The device re-enables once the temperature drops to 125
°
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.
