PIN FUNCTIONS

BLOCK DIAGRAM

SNS– (Pin 15/Pin 14), SNS+ (Pin 16/Pin 16): Current

Sense Comparator Input. Place a sense resistor in

series with the drain of the external MOSFET to set

the peak current. The SNS– pin should be connected

to the sense resistor using a minimum 100Ω resis-

tor. Use a Kelvin connection from the SNS+ pin to the

sense resistor. The current comparator trip threshold

voltage, ΔVTH is the ISET voltage divided by 20. The trip

threshold is internally clamped to a minimum of 20mV

and a maximum of 75mV. If ISET is open or greater than

2.0V, ΔVTH is set internally to 30mV.

GND (Exposed Pad Pin 17): Ground. The exposed pad

must be soldered to the PCB for rated electrical and ther-

mal performance.
