Output is 0 for low voltage, overtemperature, or illegal input. Hi-Z is for overcurrent.
control/sense circuitry
The control/sense circuitry consists of the following 3.3-V logic level pins: PWDN, RESET, ERR0, ERR1, and
SHUTDOWN. The active-low PWDN input pin powers down all internal circuitry and forces the H-bridge outputs
to the Hi-Z state. When the PWDN pin is low, the open drain ERR0, ERR1, and SHUTDOWN pins are also
disabled so that their outputs can be pulled high. The active-low RESET input pin forces the H-bridge outputs
to the low-low state and resets the overcurrent shutdown latch. The PWDN pin overrides the RESET pin. The
ERR0, ERR1, and SHUTDOWN outputs indicate the following conditions in the TAS5110A as shown in the
following table. These three outputs are open-drain connections with internal pullup resistors so that wire-ORed
connections can be made by the user with other external control devices. The short-circuit protect error
condition latches the TAS5110A in this shutdown state and forces the H-bridge outputs to the Hi-Z state until
the device is reset by means of the RESET pin. The illegal PWM input state, overtemperature, and low regulator
voltage error conditions does not latch the device in the shutdown condition. Instead the H-bridge outputs are
forced to the low-low state and the TAS5110A returns to normal operation as soon as the error condition ends.
Loss of clocking PWM signal is also considered an illegal PWM input state.
