control/sense circuitry
The control/sense circuitry consists of the following 3.3-V logic level pins: HiZ, RESET, ERR0, ERR1, and
SHUTDOWN. The active-low HiZ input pin powers down all internal circuitry and forces the H-bridge outputs
to the Hi-Z state. When the HiZ 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 over-current shutdown latch. The HiZ pin overrides the RESET pin. The ERR0,
ERR1, and SHUTDOWN outputs indicate the following conditions in the TAS5101 as shown in the table below.
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 will latch
the TAS5101 in this shutdown state and force 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, over-temperature, and low regulator voltage error
conditions will not latch the device in the shutdown condition. Instead the H-bridge outputs are forced to the
low-low state and the TAS5101 will return to normal operation as soon as the error condition ends. Loss of
clocking PWM signal is also considered an illegal PWM input state.
