3.3-V digital voltage supply for logic
Digital ground for logic is internally connected to PVSS. All three pins must be tied together but not
connected externally to PVSS. See Figure 5.

Reset and mute mode = 0, normal mode = 1; when in reset mode, H-bridge MOSFETs are in low-low
output state. Asserting the RESET signal low causes all fault conditions to be cleared.

SHUTDOWN

O
Device is in shutdown due to fault condition, normal mode = 1, shutdown = 0; when device is in
shutdown mode the H-bridge MOSFETs are in low-low output state. The latched output can be
cleared by asserting the RESET signal. This output is open drain with internal pullup resistor.
A filter capacitor must be added between the VRFILT and DVSS pins.
NOTE:The four PWM inputs: PWM_AP, PWM_AM, PWM_BP, and PWM_BM must always be connected to the TAS50xx output pins and never
left floating. Floating PWM input pins cause an illegal PWM input state signal to be asserted.
Dual pins: OUTPUTA, OUTPUTB, PVDDA1, and PVDDB1 must have both pins connected externally to the same point on the circuit board,
respectively. Both PVSS pins must also be connected ogether externally. These multiple pins are for the high-current DMOS output devices.
Failure to connect all the multiple pins to the same respective node results in excessive current flow in the internal bond wires and can cause
the device to fail. All electrical characteristics are specified and measured with all of the multiple pins of each type connected to a single node.
