Input, connect a 0.1µF or greater ceramic capacitor from
IN to GND as close to IC as possible.
Ground, connect to external exposed pad.
Enable input, logic low turns on power switch.
Enable input, logic high turns on power switch.
Active-low open-drain output, asserted during over-
current, over-temperature, or reverse-voltage conditions.
Use external resistor to set current-limit threshold;
recommended 10kΩ≦RLIM≦232kΩ.
Output
No internal connection; recommend to connect to GND
externally for improved power dissipation. . It should not
be used as electrical ground conduction path.
