Description

The LM5060 high-side protection controller provides intelligent control of a high-side N-channel MOSFET during normal on/off transitions and fault conditions. In-rush current is controlled by the nearly constant rise time of the output voltage. A POWER GOOD output indicates when the output voltage reaches the input voltage and the MOSFET is fully on. Input UVLO (with hysteresis) is provided as well as programmable input OVP. An enable input provides remote on or off control. The programmable UVLO input can be used as second enable input for safety redundancy. A single capacitor programs the initial start-up VGS fault detection delay time, the transition VDS fault detection delay time, and the continuous over-current VDS fault detection delay time. When a detected fault condition persists longer than the allowed fault delay time, the MOSFET is latched off until either the enable input or the UVLO input is toggled low and then high.
