8-PIN PACKAGE
EN or EN
GND
4
1
Enable input, logic high turns on power switch
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
(DGN ONLY)
PAD
Internally connected to GND. Connect PAD to GND plane as a heatsink for the best thermal performance.
PAD may be left floating if desired. See POWER DISSIPATION AND JUNCTION TEMPERATURE section
for guidance.
