Pin Configuration
34
ENABLE
ENABLE logic input; When this input pin is low all channels are turned off
(zero current) or remain in their last state, depending on how the channel is
programmed to respond
35
NC
Not Connected; do not connect to external supply, ground, or signal
36
V5D
Supply Voltage; 5V input for digital circuits. An external capacitor is to be
connected between this pin and GND_D near this pin
37
PHASE_SYNC
Phase Synchronization Input: Used to synchronize the rising edges of the
PWM signal on the OUTx pins for each channel
38
RESET_B
Reset Input; When this input pin is low all channels are turned off and all
internal registers are reset to the default state. The part must be held in reset
by an external source until all supplies are stable and within tolerance
39
CLK
CLOCK; Main clock input for the chip. A clock input of 20 MHz to 40 MHz is
required
40
GND_D
Ground; ground pin for digital circuits
41
GNDSD
Ground; ground pin for substrate connection near digital circuits
42
FAULT
Fault Output Pin; Open drain output pin is pulled low when a fault condition
is detected. Certain faults can be masked via SPI
43
V_SIGNAL
Supply Voltage; Supply pin for the SPI SO output and the pull-up current
sources of the digital inputs CS_B and RESET_B. An external capacitor must
be connected between this pin and GND_D near this pin
44
SO
SPI Serial Data Out
45
SI
SPI Serial Data In
46
SCK
SPI Serial Clock Input
47
CS_B
SPI Chip Select Bar; active low signal
48
NC
Not Connected; do not connect to external supply, ground, or signal
49
POS3
Channel #3 Positive sense pin; Connect to the “l(fā)oad” side of the external
sense resistor
50
NEG3
Channel #3 Negative sense pin; Connect to the “FET” side of the external
sense resistor
51
NEG2
Channel #2 Negative sense pin; Connect to the “FET” side of the external
sense resistor
52
POS2
Channel #2 Positive sense pin; Connect to the “l(fā)oad” side of the external
sense resistor
53
NC
Not Connected; do not connect to external supply, ground, or signal
54
OUT3
Gate driver output for channel #3; Connect to the gate of the external
MOSFET
55
OUT2
Gate driver output for channel #2; Connect to the gate of the external
MOSFET
56
V5A3
Supply Voltage;5V input for analog. An external capacitor is to be connected
between this pin and GND_A near this pin.
57
NC
Not Connected; do not connect to external supply, ground, or signal
58
GND_A3
Ground; ground pin for analog circuits
59
OUT1
Gate driver output for channel #1; Connect to the gate of the external
MOSFET
