High-Side Protection Controller 10-Pin MSOP T/R
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 Under-Voltage Lock-Out, with hysteresis, is provided as well as programmable input Over-Voltage Protection. An enable input provides remote On / Off control. The programmable Under-Voltage Lock-Out 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 Under-Voltage Lock-Out input is toggled low and then high.
