PWM input B()
RESET
14
3
I
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
5
12
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.
VRFILT
10
7
O
A filter capacitor must be added between 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 causes 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 together 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 connected to the same
node, respectively.
