DEVICE INFORMATION
PIN FUNCTIONS
NAME PINS DESCRIPTION
8-PIN PACKAGE
EN or EN 4 Enable input, logic high turns on power switch
GND 1 Ground connection
IN 2, 3 Input voltage and power-switch drain; connect a 0.1 µF or greater ceramic capacitor from IN to GND close
to the IC
FLT 5 Active-low open-drain output, asserted during over-current, or over-temperature conditions
OUT 6, 7, 8 Power-switch output, connect to load
PowerPAD PAD Internally connected to GND. Connect PAD to GND plane as a heatsink for the best thermal performance.
(DGN ONLY) PAD may be left floating if desired. See POWER DISSIPATION AND JUNCTION TEMPERATURE section
for guidance.
