SLAS644B – JULY 2009 – REVISED OCTOBER 2009
The TLV320AIC3111 has a short-circuit protection feature for the speaker drivers that is always enabled
to provide protection. If the output is shorted, the output stage shuts down on the overcurrent condition.
(Current limiting is not an available option for the higher-current speaker driver output stage.) In case of a
short circuit on either channel, the output is disabled and a status flag is provided as a read-only bit on
page 1 / register 32, bit D0.
If shutdown occurs due to an overcurrent condition, then the device requires a reset to re-enable the
output stage. Resetting can be done in two ways. First, the device master reset can be used, which
requires either toggling the RESET pin or using the software reset. If master reset is used, it resets all of
the registers. Second, a dedicated speaker power-stage reset can be used that keeps all of the other
device settings. The speaker power-stage reset is done by setting page 1 / register 32, bit D7 for SPLP
and SPLM and by setting page 1 / register 32, bit D6 for SPRP and SPRM. If the fault condition has been
removed, then the device returns to normal operation. If the fault is still present, then another shutdown
occurs. Repeated resetting (more than three times) is not recommended, as this could lead to
overheating.
To minimize battery current leakage, the SPLVDD and SPRVDD voltage levels should not be less
than the AVDD voltage level.
The TLV320AIC3111 has a thermal protection (OTP) feature for the speaker drivers which is always
enabled to provide protection. If the device is overheated, then the output stops switching. When the
device cools down, the device resumes switching. An overtemperature status flag is provided as a
read-only bit on page 0 / register 3, bit D1. The OTP feature is for self-protection of the device. If die
temperature can be controlled at the system/board level, then overtemperature does not occur.
5.6.13 Audio Output-Stage Power Configurations
After the device has been configured (following a RESET) and the circuitry has been powered up, the
audio output stage can be powered up and powered down by register control.
These functions soft-start automatically. By using these register controls, it is possible to turn all four
stages on at the same time without turning two of them off.
See Table 5-39 for register control of audio output stage power configurations.

CLOCK Generation and PLL
The TLV320AIC3111 supports a wide range of options for generating clocks for the ADC and DAC
sections as well as interface and other control blocks as shown in Figure 5-36. The clocks for the ADC
and DAC require a source reference clock. This clock can be provided on variety of device pins, such as
the MCLK, BCLK, or GPIO1 pins. The source reference clock for the codec can be chosen by
programming the CODEC_CLKIN value on page 0 / register 4, bits D1–D0. CODEC_CLKIN can then be
routed through highly-flexible clock dividers shown in Figure 5-36 to generate the various clocks required
