TAS5805MEVM: TAS5805EVM found the temperature was too high

Kevin Huang8

Part Number: TAS5805MEVM
Other Parts Discussed in Thread: TAS5825M, TAS5805M

Hello!

My customer tested TAS5805EVM found the temperature was too high. His settings are as below.

(1)Audio input source: AP Processor input I2S did not send any audio source signal.
(2)Speaker uses 8ohm cement Resistance setting.

Excuse me, do you know how much W is consumed by TAS5805EVM when it is empty? The customer currently sets the input consumption to 5W.
What is wrong with the customer's settings, can you guide me on how to catch each bug?
Excuse me, how can I reduce the power consumption?
If you need more information, please tell me, I can go to the customer to measure again.

Hi Kevin,

When the customer is saying the device is getting too hot, are they saying the device is entering thermal shutdown? And this is occuring even with the device isn't receiving any signal?

We have the idle current consumption numbers found in the TAS5825M datasheet (page 6 and 7).

Would your customer be able to share what settings they have placed the device under?

Thanks,

Robert Clifton

Hi Team,

Turn on system 10 minutes is hot does not crash; the audio input signal is I2S -16.3dBFS level. Po is 3.16Vrms

And Rigster setting as below.

typedef union {
struct {
cfg_u8 offset;
cfg_u8 value;

struct {
cfg_u8 command;
cfg_u8 param;

#define CFG_META_SWITCH (255)
#define CFG_META_DELAY (254)
#define CFG_META_BURST (253)

/* Example C code */
/*
// Externally implemented function that can write n-bytes to the device
// PCM51xx and TAS5766 targets require the high bit (0x80) of the I2C register to be set on multiple writes.
// Refer to the device data sheet for more information.
extern int i2c_write(unsigned char *data, int n);
// Externally implemented function that delays execution by n milliseconds
extern int delay(int n);
// Example implementation. Call like:
// transmit_registers(registers, sizeof(registers)/sizeof(registers[0]));
void transmit_registers(cfg_reg *r, int n)

Hi,

The TAS5805M EVM board was used during customer testing, or customer board?

If TAS5825M EVM boad, which device was used? Above beads or bottom inductor. Regarding the test condition, please confirm below:

how to judge 'too hot'? Is possible to measure case temperature?
What's the PVDD voltage, speaker load, output power?
Please capture output PWM waveform (idle and play power).
Share us your PPC3 file.

Regards
