detailed description (continued)
VSENSE1, VSENSE2
– VSENSE1 and VSENSE2 can be used to detect undervoltage conditions on external
circuitry. If VSENSE1 senses a voltage below approximately 1.23 V, PWRGD1 is pulled low. Similarly, a voltage
less than 1.23 V on VSENSE2 causes PWRGD2 to be pulled low.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
