PIN TYPE(1) DESCRIPTION
NAME NO.
LCOM 1 A Common coil input
LSENSE 2 A Sense coil input
LREF 3 A Reference coil input
ADJ 4 A Threshold adjust pin
OUT 5 O Switch output
EN 6 I Enable input
GND 7 G Ground
VDD 8 P Power Supply
DAP DAP G Connect to Ground for improved thermal performance(2)
(1) I = Input, O = Output, P = Power, A = Analog, G = Ground
(2) There is an internal electrical connection between the exposed Die Attach Pad (DAP) and the GND pin of the device. Although the DAP can be left floating, for best performance the DAP should be connected to the same potential as the device's GND pin. Do not use the DAP as the primary ground for the device. The device GND pin must always be connected to ground.
