These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Operation at the absolute
maximum rating for extended periods may reduce device reliability.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken
when handling and transporting these devices.
Notes:
1. Measured with respect to GND pin
2. Subject to absolute maximum V

not being exceeded.
3.
V
SENSE
is defined as the voltage difference across the sense resistor, R

.
4. The usable V
SENSE
range is limited by the output voltage range; and as such will be reduced at lower V
S+
values.
