 Description
The DIO1298 is a load switch for USB VBUS safety
management, which could provide up to 165 W
current-sink input for 28 V EPR systems. It stands out
with a broad operating voltage from 3 V to 32 V. With
a continuous current rating of 6 A, it's well equipped
for power intensive tasks.
This device integrates an array of safety features.
Soft start functionality smoothly ramps up power,
curbing inrush current. It offers both internal and
external adjustable overvoltage protection. The "ideal
diode" reverse current protection, with a mere 20 mV
forward voltage drop and rapid 15 μs recovery,
prevents unwanted current flow. Moreover, it includes
short circuit, overcurrent, and overtemperature
protection, along with robust transient voltage
suppression against ESD and surges.
The DIO1298 supports a low RDS(ON) in a tiny package
WLCSP (2.53 mm × 2.53 mm), it could provide a
highly efficient and space saving solution for such as
notebook, PC, monitors or other applications.
