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.

NOTE 1: All voltages are respect to DGND.
