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.
