This is done by: • Connect INPL and INNL directly to Ground (without capacitors) this sets the device in Mono mode during power up. • Connect OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together for the negative terminal • Analog input signal is applied to INPR and INNR DEVICE PROTECTION SYSTEM The TPA31xxD2 family contains a complete set of protection circuits carefully designed to make system design efficient as well as to protect the device against any kind of permanent failures due to short circuits, overload, over temperature, and under-voltage. The FAULTZ pin will signal if an error is detected according to the fault table below: Table 4. Fault Reporting TRIGGERING CONDITION LATCHED/SELF- FAULT FAULTZ ACTION (typical value) CLEARING Over Current Output short or short to PVCC or GND Low Output high impedance Latched Over Temperature Tj > 150°C Low Output high impedance Latched Too High DC Offset DC output voltage Low Output high impedance Latched Under Voltage on PVCC < 4.5V – Output high impedance Self-clearing PVCC Over Voltage on PVCC > 27V – Output high impedance Self-clearing PVCC DC DETECT PROTECTION The TPA31xxD2 family has circuitry which will protect the speakers from DC current which might occur due to defective capacitors on the input or shorts on the printed circuit board at the inputs. A DC detect fault will be reported on the FAULT pin as a low state. The DC Detect fault will also cause the amplifier to shutdown by changing the state of the outputs to Hi-Z. If automatic recovery from the short circuit protection latch is desired, connect the FAULTZ pin directly to the SDZ pin. This allows the FAULTZ pin function to automatically drive the SDZ pin low which clears the DC Detect protection latch. A DC Detect Fault is issued when the output differential duty-cycle of either channel exceeds 60% for more than 420 msec at the same polarity. Table x below shows some examples of the typical DC Detect Protection threshold for several values of the supply voltage. This feature protects the speaker from large DC currents or AC currents less than 2Hz. To avoid nuisance faults due to the DC detect circuit, hold the SD pin low at power- up until the signals at the inputs are stable. Also, take care to match the impedance seen at the positive and negative inputs to avoid nuisance DC detect faults. The minimum output offset voltages required to trigger the DC detect are show in Table 5. The outputs must remain at or above the voltage listed in the table for more than 420 msec to trigger the DC detect. 18 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Link(s): TPA3116D2 TPA3118D2 TPA3130D2 |
