MP5006
The Future of Analog IC Technology
MP5006
5V, 1A- 5A Programmable Current
Limit Switch with Slew Rate Control and
Auto Enable
DESCRIPTION
The MP5006 is a protection device designed to
protect circuitry on the output (VOUT) from
transients on input (VIN). It also protects VIN from
undesired shorts and transients coming from the
load.
At start up, inrush current is controlled by limiting
the slew rate at the VOUT. The slew rate is
controlled by a small capacitor at the dv/dt pin.
The dv/dt pin has an internal circuit that allows
the customer to float this pin (no connect) and
still receive a 1.1ms ramp time at the VOUT.
The max load at the output (VOUT) is current
limited. This is accomplished by utilizing a sense
FET topology. The magnitude of the current limit
is controlled by an external resistor connected
between the ILIMIT pins.
An internal charge pump drives the gate of the
power device, allowing a very low on-resistance
DMOS power FET of just 0.044.
VOUT is protected from VIN being too low or too
high. Under Voltage Lockout (UVLO) assures
that the input is above the minimum operating
threshold, before the power device is turned on.
If VIN goes above the high output threshold, the
output voltage will be limited.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX) the junction-to-
ambient thermal resistance θJAand the ambient temperature
TA, the maximum allowable power dissipation at any ambient
temperature is calculated using: PD(MAX)=(TJ(MAX)-TA)/ θJA.
Exceeding the maximum allowable power dissipation will
cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
Reduce 0.2 Watts for every 10oC ambient temperature
