Pin Functions

NAME PIN Type(1) DESCRIPTION
D1 1 O Open drain output of the first power MOSFETs. Typically connected to the outer terminals of the center tap transformer. Because large currents flow through these pins, the external traces must be kept short.
D2 2 O Open drain output of the second power MOSFETs. Typically connected to the outer terminals of the center tap transformer. Because large currents flow through these pins, the external traces must be kept short.
GND1 3 — Ground connection for VCC1
GND2 9 — Ground connection for VCC2
15
INA 5 I Input, channel A
INB 6 I Input, channel B
INC 7 I Input, channel C
IND 10 I Input, channel D
NC 14 — Not connected
OUTA 13 O Output, channel A
OUTB 12 O Output, channel B
OUTC 11 O Output, channel C
OUTD 8 O Output, channel D
VCC1 4 — Power supply, side 1
VCC2 16 — Power supply, side 2
(1) I = Input, O = Output
