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.
