MP5016H
The Future of Analog IC Technology
2.7 - 22V, 0.7 - 5A, Current Limit Switch
with Over-Voltage Clamp and Reverse Block
DESCRIPTION
FEATURES
The MP5016H is a protection device designed
to protect circuitry on the output from transients
on the input. The MP5016H also protects the
input from undesired shorts and transients
coming from the output.
During start-up, the inrush current is limited by
limiting the slew rate at the output. The slew
rate is controlled by the DV/DT pin setting and
MODE pin setting.
The maximum load at the output is currentlimited. The magnitude of the current limit is
controlled by an external resistor from ILIMIT to
GND. There is a fixed 2.5A current limit when
ILIMIT is floating.
The output voltage is limited by the output overvoltage protection (OVP) function. The clamp
voltage can be set by the MODE connection.
The MP5016H offers a GATE drive signal
connected to an external N-channel MOSFET
gate to block current flowing from the output to
the input when the IC is in enable off, power
shutdown, or thermal shutdown.
The MP5016H is available in a QFN-10
(1.5mmx2mm) package.

MP5016H – 2.7 - 22V, 0.7 - 5A, PROGRAMMABLE, CURRENT-LIMITED SWITCH
OPERATION
The MP5016H is designed to limit the inrush
current to the load when a circuit card is
inserted into a live backplane power source,
thereby limiting the backplane’s voltage drop
and the dV/dt of the voltage to the load. The
MP5016H offers an integrated solution that
monitors the input voltage, output voltage,
output current, and die temperature, which
eliminates the requirement of an external
current sense power resistor, power MOSFET,
and thermal sense device.
Under-Voltage Lockout (UVLO)
The MP5016H can be used in a 2.7V to 22V
input supply system. There are high-energy
transients during normal operation or hot swaps.
These transients depend on the parasitic
inductance and resistance of the wire and the
capacitor at the VCC node. If a power clamp
(TVS, Tranzorb) diode is not used, the E-fuse
must be able to withstand this transient voltage.
The MP5016H integrates a high-voltage
MOSFET with up to 22V of continuous voltage
and 26V of maximum transient input voltage.
The MP5016H also uses a high-voltage circuit
for the VCC node to guarantee safe operation.
MODE
MODE is used to select the output over-voltage
protection (OVP) threshold.
Three digital inputs are provided for MODE.
Drive MODE high to VCC to set the output OVP
clamp voltage at 15.2V. Drive MODE low to
GND to set the output OVP clamp voltage at
5.75V. Float MODE for no OVP clamp
protection. The OVP threshold can also be set
by connecting a resistor from MODE to ground.
For more details, refer to the Application
Information section on page 13.
Soft Start (SS)
The soft-start time is related to the dV/dt slew
rate and input voltage and can be calculated
with Equation (1):
t_ss(ms)
Vin(V)
dv/dt (V/ms)
(1)
Fast Output and Input OVP
To protect the downstream load when there is a
surge voltage at the input, the MP5016H
provides an output OVP function. An accurate
and fast comparator monitors the over-voltage
condition of the output. If the output voltage
rises above the threshold set by MODE, the
gate of the internal MOSFETs is pulled down
quickly and is regulated to a certain value to
keep the output voltage clamped at the OVP
threshold. The fast loop response speed keeps
the over-voltage overshoot small.
Current Limit (ILIMIT)
The MP5016H provides a constant current limit,
and the current limit can be programmed by an
external resistor.
The desired current limit is a function of the
external current limit resistor and can be
approximated with Equation (2):
ILIMIT (A)
0.55(V)
3870
RLIMIT (Ω）
(2)
Where 3870 is the current sense ratio.
Once the current limit threshold is reached, the
internal circuit regulates the gate voltage to hold
the current in the power MOSFET constant. To
limit the current, the gate to the source voltage
must be regulated from 5V to around 1V. The
typical response time is about 15µs. During this
period, the output current may have a small
overshoot.
If the current limit condition lasts longer than
2ms, the IC enters hiccup mode with 2ms of on
time and 700ms of off time.
The MP5016H allows ILIMIT to be floated
during operation. If ILIMIT is floating, the
current limit is set at a fixed 2.5A internally.
When shorting ILIMIT to GND, the normal
current limit is disabled, but the secondary
current limit still works. The secondary current
limit is set to 8A internally. When the secondary
current limit is triggered, the IC shuts down the
power MOSFET.
The dV/dt slew rate is controlled by an external
DV/DT capacitor setting and the MODE setting.

MP5016H – 2.7 - 22V, 0.7 - 5A, PROGRAMMABLE, CURRENT-LIMITED SWITCH
Short-Circuit Protection (SCP)
If the load current increases rapidly due to a
short-circuit event, the current may exceed the
current-limit threshold before the control loop
can respond. If the current reaches the 8A
secondary current limit level, a fast turn-off
circuit activates to turn off the power MOSFET.
This can help limit the peak current through the
switch, keeping the input voltage from dropping
too much. The total short-circuit response time
is about 1µs. After the MOSFET has switched
off, the part restarts. During the restart process,
if the short still exists, the MP5016H regulates
the gate voltage to hold the current at a normal
current limit level. The IC enters hiccup mode
with 2ms of on time and 700ms of off time.
To prevent safe operating area (SOA) damage
during a high input voltage short-circuit
protection (SCP) condition, the IC current limit
folds back when the power MOSFET VDS
voltage is above the typical 11V and the
junction temperature is over 110°C.
To avoid large input voltage spikes from
damaging the IC during SCP entry, it is
recommended to use a 22μF minimum input
capacitor when VIN is higher than 15V. If the
input surge voltage is higher than the 26V
absolute voltage, the IC may be damaged.
Reverse-Blocking MOSFET Driver
The MP5016H has a GATE pin to provide an
external N-channel MOSFET gate drive signal
for reverse-current protection (RCP). Three
events can pull down the GATE voltage: VIN
below the under-voltage lockout (UVLO), the
enable (EN) voltage below the low level
threshold, or thermal shutdown. If any of these
conditions occur, GATE sinks the current from
the gate of the external MOSFET to initiate a
fast turn-off.
For 3.3V low input voltage applications, choose
an external reverse-blocking MOSFET with a
small gate threshold voltage (VGSth < 1.6V) to
reduce the voltage drop caused by the reverseblocking MOSFET.
Setting an appropriate OVP threshold can also
protect the reverse voltage (from the output to
the input) when using an external N-channel
MOSFET. When VOUT rises too high during
normal operation, the MP5016H SOURCE
MP5016H Rev.1.2
11/11/2020
voltage is higher than the OVP threshold. In this
case, the GATE voltage is regulated to maintain
the SOURCE clamped at the OVP threshold.
This action protects the reverse current from
the high VOUT to the low VIN.
A 100pF capacitor is required on GATE if it is
not connected to the external MOSFET.
Output Discharge
The MP5016H involves a discharge function
that provides a resistive discharge path for the
external output capacitor. The function is active
when the part is disabled (VIN UVLO, EN
shutdown) and is done in a very limited amount
of time. When using the external reversecurrent block MOSFET, the output discharge
path is blocked by the reverse current block
MOSFET. Therefore, the output cannot be
discharged when the reverse-current block
MOSFET is used.
Enable (EN)
The MP5016H is enabled when EN is high. The
MP5016H is disabled when EN is low. Floating
EN shuts down the MP5016H because there is
an internal 2.2MΩ resistor pulling EN down to
ground. For automatic start-up, connect a pullup resistor from VCC to EN.
EN is clamped internally using a 5.5V Zener
diode (see Figure 2). Connecting the EN input
through a pull-up resistor to VCC limits the EN
input current below 100μA to prevent damage
to the Zener diode. For example, when
connecting a 300kΩ pull-up resistor to 22V VCC,
IZener = (22V - 5.5V) / 300kΩ - 5.5V / 2.2MΩ =
53µA.
Figure 2: Zener Diode between EN and GND
When using a pull-up resistor to set the poweron threshold, avoid using a pull-up resistor that
is too small to increase the operational
quiescent current.

Thermal Shutdown – Auto-Retry
Thermal shutdown prevents the chip from
operating at exceedingly high temperatures.
When the silicon die temperature exceeds
175°C, the entire chip shuts down, and EN
reports a fail mode. When the temperature
drops below its lower threshold (typically
125°C), the chip is enable again after a 700ms
delay, typically.

APPLICATION INFORMATION
Setting the Current Limit
The MP5016H current limit value should
exceed the normal maximum load current,
allowing for tolerances in the current sense
value. The current limit is a function of the
external current limit resistor. Table 1 and
Figure 3 list examples of typical current limit
values as a function of the resistor value.

The OVP threshold can also be set by
connecting a resistor from MODE to ground. In
this case, the OVP clamp threshold is given by
Equation (3):
Vclamp (V) 0.047 RMODE (KΩ） 0.3(V) (3)
RMODE should be above 68kΩ. For example, an
RMODE value of 76.8kΩ can set the OVP clamp
threshold to 3.9V.
When RMODE is used, place a 39pF capacitor
from MODE to GND.

Figure 3: Current Limit vs. Current Limit Resistor
The MP5016H current limit can be programmed
from 0.7A to 5A by connecting the correct
resistor (RLIMIT). The current limit cannot be set
too low, because the MP5016H works in sleep
mode when the load is lower than 0.38A,
typically. The current limit logic is disabled in
sleep mode, also.
Setting the Over-Voltage Clamp Threshold
Drive MODE high to VCC to set the output OVP
clamp voltage at 15.2V. Drive MODE low to
GND to set the output OVP clamp voltage at
5.75V.
Refer to Table 2 to set the MODE high/low
digital voltage.

For example, when the external DV/DT cap is

is 1V/ms.
Large Output Capacitor
With large output capacitors, if the charge
current during soft start triggers the current limit,
the MP5016H enters hiccup mode when the
current limit is triggered for 2ms.To avoid startup failure with a large output capacitor, a proper
dV/dt slew rate must be set during the soft start
to avoid triggering the current limit.
PCB Layout Guidelines
Efficient PCB layout is critical for stable
operation. For best results, refer to Figure 4 and
follow the guidelines below.
1. Place the high-current paths (VCC, VOUT)
close to the device using short, direct, and
wide traces.
2. Place the input capacitors close to VCC and
GND.

detailed device applications, please refer to the
related evaluation board datasheet.
3. Connect the VCC and VOUT pads to a
large VCC and VOUT plane respectively to
achieve better thermal performance.
4. Place a current-limit resistor close to ILIMIT.
5. Place the DV/DT capacitor close to DV/DT.

NOTES:
9) To avoid large input voltage spikes from damaging the IC during SCP entry, it is recommended to use a 22μF minimum input capacitor
when VIN is higher than 15V.
10) For 3.3V low input voltage applications, it is recommended to choose an external reverse-blocking MOSFET with a small gate threshold
voltage (VGSth < 1.6V) to reduce the voltage drop caused by the reverse-blocking MOSFET.
