2.2 Control/Miscellaneous
Pin Name
Pin No.
Description
PWRDN
25
Power Down (0=Shutdown, 1= Normal).
TRI-STATE
FAULT [Note 7]
TWARN [Note 7]
CONFIG [Note 8]
26
Tri-State (0=All MOSFETS Hi-Z, 1=Normal).
27
Fault output indicator; Overcurrent, Overvoltage or Overtemperature
(0=Fault, 1=Normal).
28
Thermal warning output
(0=Warning T_J >= 130°C, 1=Normal).
24
Configuration (0=Normal, 1=Parallel operation for mono).
NC
18
Do not connect.
Note 7: FAULT and TWARN outputs are open-drain
Note 8: Connect CONFIG Pin 24 to VREG1 Pins 21, 22 to implement single bridge (mono mode) operation
for high current.
2.3 Power Outputs for DDX^® Mode or Binary Full Bridge Mode [Note 9]
Pin Name
Pin No.
Description
OUTPL
16, 17 Left output, positive reference
OUTNL
10, 11 Left output, negative reference
OUTPR
8, 9
Right output, positive reference
OUTNR
2, 3
Right output, negative reference
Note 9: DDX^® outputs are bridged. The outputs OUTPx produce signals in phase with the input.
2.4 Power Outputs for Binary Half-Bridge Mode [Note 10]
Pin Name
Pin No.
Description
OUTNR
2, 3
CH4 output, positive reference
OUTPR
8, 9
CH3 output, positive reference
OUTNL
10, 11 CH2 output, positive reference
OUTPL
16, 17 CH1 output, positive reference
Note 10: Half-Bridge Binary Mode outputs are NOT bridged. All outputs produce signals in phase with the
input.
