MP5000A
The Future of Analog IC Technology
DESCRIPTION
The MP5000A is a protection device designed to
protect circuitry on the output (source) from
transients on input (VCC). It also protects VCC from
undesired shorts and transients coming from the
source.
At start up, inrush current is limited by limiting the
slew rate at the source. 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 0.9ms ramp time at the source.
The maximum load at the output (source) is
current limited. This is accomplished by utilizing a
sense FET topology. The magnitude of the
current limit is controlled by an external resistor
from the I-Limit pin to the Source pin.
An internal charge pump drives the gate of the
power device, allowing a very low on-resistance
DMOS power FET of just 40m.
The source is protected from the VCC input being
too low or too high. Under Voltage Lockout
(UVLO) assures that VCC is above the minimum
operating threshold, before the power device is
turned on. If VCC goes above the high output
threshold, the source voltage will be limited.
