7.3 Feature Description
7.3.1 Error Reporting
The FAULT, and CLIP_OTW, pins are active-low, open-drain outputs. The function is for protection-mode
signaling to a system-control device.
Any fault resulting in device shutdown is signaled by the FAULT pin going low. Also, CLIP_OTW goes low when
the device junction temperature exceeds 125°C (see Table 3).

1
1
Junction temperature lower than 125°C and no OLP or UVP faults (normal operation)
Note that asserting either RESET low forces the FAULT signal high, independent of faults being present. TI
recommends monitoring the CLIP_OTW signal using the system microcontroller and responding to an
overtemperature warning signal by, that is, turning down the volume to prevent further heating of the device
resulting in device shutdown (OTE).
To reduce external component count, an internal pullup resistor to 3.3 V is provided on both FAULT and
CLIP_OTW outputs.
7.4 Device Functional Modes
7.4.1 Device Protection System
The TPA3244 device contains advanced protection circuitry carefully designed to facilitate system integration and
ease of use, as well as to safeguard the device from permanent failure due to a wide range of fault conditions
such as short circuits, overload, overtemperature, and undervoltage. The TPA3244 device responds to a fault by
immediately setting the power stage in a high-impedance (Hi-Z) state and asserting the FAULT pin low. In
situations other than overload and overtemperature error (OTE), the device automatically recovers when the fault
condition has been removed, that is, the supply voltage has increased.
The device will function on errors, as shown in Table 4.

Bootstrap UVP does not shutdown according to the table, it shuts down the respective halfbridge (non-latching,
does not assert FAULT).
7.4.1.1 Overload and Short Circuit Current Protection
The TPA3244 device has fast reacting current sensors with a programmable trip threshold (OC threshold) on all
high-side and low-side FETs. To prevent output current to increase beyond the programmed threshold, TPA3244
has the option of either limiting the output current for each switching cycle (Cycle By Cycle Current Control,
CB3C) or to perform an immediate shutdown of the output in case of excess output current (Latching Shutdown).
CB3C prevents premature shutdown due to high output current transients caused by high level music transients
