PRODUCTION DATA
The TPS7B4255-Q1 incorporates a back-to-back PMOS topology that protects the device from damage against a fault condition, resulting in VOUT being higher than VIN and the subsequent flow of reverse current. No damage occurs to the device if this fault condition occurs, provided the Absolute Maximum Ratings are not violated. This integrated protection feature eliminates the need for an external diode. The reverse current comparator typically responds to a reverse voltage condition in 1 μs, and along with the body diode of the blocking PMOS transistor, limits the reverse current to IREV.
