detailed description (continued)

OC1, OC2, OC3, OC4

OCx is an output signal that is asserted (active low) when an overcurrent or overtemperature condition is

encountered for the corresponding channel. OCx will remain asserted until the overcurrent or overtemperature

condition is removed.

EN1, EN2, EN3, EN4,

The active-low logic input ENx enables or disables the power switches in the device. The enable input is

compatible with both TTL and CMOS logic levels. The switches will not turn on until 3.3V_OUT is above the PG

threshold.

† 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.

‡ All voltages are with respect to GND.
