Any fault resulting in device shutdown is signaled by the FAULT pin going low (see Table 1). A sticky version of
this pin is available on D1 of register 0X02.

DESCRIPTION

Overcurrent (OC) ERROR
1
No faults (normal operation)
The device has independent, fast-reacting current detectors on all high-side and low-side power-stage FETs,
which protects against shorts across the load, to GND, or to PVCC. The protection system triggers a latching
shutdown, resulting in the power stage being set in the high-impedance (Hi-Z) state and FAULT being asserted
low. The device returns to normal operation once the fault condition (i.e., a short circuit on the output) is
removed. Current limiting and overcurrent protection are not independent for half-bridges. That is, if the
bridge-tied load between half-bridges A and B causes an overcurrent fault, half-bridges A, B, C, and D are shut
down.
The TAS5710 has an over-temperature protection system. If the device junction temperature exceeds 150°C
(nominal), the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the
high-impedance (Hi-Z) state. The TAS5710 recovers automatically once the temperature drops approximately
15°.
THE UVP circuits of the TAS5710 fully protect the device in any power-up/down and brownout situation. The
UVP engages if PVCC_X = AVCC drops below 8.4-V (typical) and disengages when PVCC_X = AVCC exceeds
8.5-V. The OVP circuits protect against voltage spikes and engage when PVCC_X = AVCC exceeds 27.5-V
(typical). The OVP circuits disengage when PVCC_X = AVCC drops below 27.2-V. When the protection circuits
engage, all half-bridge outputs are immediately placed in the high-impedance (Hi-Z) state.
Serial data is input on SDIN. The PWM outputs are derived from SDIN. The TAS5710 DAP accepts serial data in
16-, 20-, or 24-bit left-justified, right-justified, and I2S serial data formats.
The TAS5710 is a slave device. It accepts MCLK, SCLK, and LRCLK. The digital audio processor (DAP)
supports all the sample rates and MCLK rates that are defined in the clock control register.
The TAS5710 checks to verify that SCLK is a specific value of 32 fS, 48 fS, or 64 fS. The DAP only supports a 1 ×
fS LRCLK. The timing relationship of these clocks to SDIN is shown in subsequent sections. The clock section
uses MCLK or the internal oscillator clock (when MCLK is unstable, out of range, or absent) to produce the
internal clock (DCLK) running at 512 times the PWM switching frequency.
The DAP can autodetect and set the internal clock control logic to the appropriate settings for all supported clock
rates as defined in the clock control register.
TAS5710 has robust clock error handling that uses the bulit-in trimmed oscillator clock to quickly detect
changes/errors. Once the system detects a clock change/error, it will mute the audio (through a single step mute)
and then force PLL to limp using the internal oscillator as a reference clock. Once the clocks are stable, the
system will auto detect the new rate and revert to normal operation. During this process, the default volume will
be restored in a single step (also called hard unmute). The ramp process can be programmed to ramp back
slowly (also called soft unmute) as defined in volume register (0X0E).
