PIN INFORMATION FOR VT1697SB SMART SLAVE DEVICE

VDDH (Pin 1): 12V input supply voltage node. This node con-

nects to the 12V input power supply source. High-frequency

decoupling capacitors must be placed in close proximity to

the slave IC on the same side as the VT1697SB. See Table 2

for reference.

VSS (Pins 2-5): Power switch ground node. These nodes

normally connect directly to the ground plane.

VX (Pins 6-9): Switching node. These nodes connect the

switching node of the power devices to the output inductor.

BST (Pin 10): Bootstrap supply for high-side drivers.

VCC (Pin 11): 1.8V supply for low-side drivers.

VDD (Pin 12): 1.8V supply for control circuits.

PWM (Pin 13): PWM input node. Connect this node to the

PWM output pin from the Master.

GND (Pin 14): Ground for control circuits.

ISENSE (Pin 15): Current sense output node. Connect this

node to the current sense input of the Master through a sim-

ple passive filter.

TS_FAULTB (Pin 16): Temperature sense and fault output

node. Connect this node to the temperature sense pin of the

Master through a simple passive filter.
