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

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.
