SP2526A
Dual Channel USB Power Distribution Switch
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
Supply Voltage VIN ................................................. 7.0V
Fault Flag Voltage VFLG............................................ 7.0V
Fault Flag Current IFLG ...........................................50mA
Enable Input VEN......................................... -0.3V to 15V
Storage Temperature .............................. -65°C to 150°C
Soldering Temperature (10sec) ............................. 260°C
Maximum Junction Temperature............................ 125°C
Power Dissipation (NSOIC-8) .........................................
(derate 6.14mW/°C above 70°C)...................... 500mW
OPERATING RATINGS
Ambient Temperature Range ..................... -40°C to 85°C
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Ambient Temperature of TA = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at TA = 25°C, and are provided
for reference purposes only. Unless otherwise indicated, VIN = 5.0V, TA= 25°C.
