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 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 V_GS fault detection delay time, the transition V_DS fault detection delay time, and the continuous Over-
Current V_DS 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.
