General Description

The SLG59M1649V is a self-powered, high-performance,

23 mΩ pFET load switch designed for 1.5 V to 5.5 V power rail

applications up to 4 A. When enabled, internal reverse-current

protection will quickly open the switch in the event of a

reverse-voltage condition is detected

(a VOUT + 50 mV > VIN condition opens the switch). Upon the

detection of a reverse condition, an open-drain FAULT output

is asserted. In the event the VIN voltage is too low, the load

switch also contains an internal VIN(UVLO) threshold monitor to

keep or to turn the switch OFF.

Designed to operate over a -40°C to 85°C range, the

SLG59M1649V is available in a RoHS-compliant, ultra-small

1.0 x 1.6 mm STDFN package.
