Current-limit level set. Place a resistor between ILIM and GND to achieve a highaccuracy current limit.
Output voltage adjustment. ADJ sinks a current from the upstream DC/DC
converter's FB pin to ground to regulate the DC/DC converter's output voltage. ADJ
also supports a line drop compensation function.
USB mode control. Float MODE to operate the USB in DCP mode. Pull MODE low
to operate the USB in CDP mode. MODE has a 1MΩ pull-up resistor to an internal
+1.2V source.

Open-drain output. Pull STATUS low when the load current is higher than the
typical 90mA threshold. STATUS is an open drain during no-load conditions.
Enable pin for the IC. EN has an internal auto pull-up current to VCC. Float EN or
apply a logic high voltage to EN to enable the IC. Pull EN to logic low to disable the

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-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage. Measured on EV5030D-QH-00A, 2-layer PCB,
4.4cmx2.9cm, 2Oz copper.
3) The device is not guaranteed to function outside of its
operating conditions.
4) For lower VIN applications, refer to the Operation section on
page 12.
5) Measured on EV5030D-QH-00A, 4.4cmx2.9cm, 2-layer PCB,
2Oz copper.
6) The value of θJA given in this table is only valid for comparison
with other packages and cannot be used for design purposes.
These values were calculated in accordance with JESD51-7,
and simulated on a specified JEDEC board. They do not
represent the performance obtained in an actual application.

MP5030D – USB CHARGING PORT CONTROLLER SUPPORTING CDP AND DCP
OPERATION
The MP5030D integrates a USB current-limit
switch and charging port identification circuitry.
The MP5030D achieves 3A of continuous
output current over a wide input supply range.
The output of the USB switch is current-limited
with an adjustable current-limit threshold. The
MP5030D supports DCP and CDP schemes for
battery charging specification (BC1.2), divider
mode, and 1.2V/1.2V mode without the need for
external user interaction.
The
MP5030D
provides
line
drop
compensation, load current detection, and
status indication. Full protection features
include hiccup current limiting, input overvoltage protection (OVP), and thermal
shutdown.
Operation Supply Voltage
The MP5030D has a two-stage input voltage
threshold: the first threshold is around 3V, and
the second threshold is the under-voltage
lockout (UVLO) of the power MOSFET. When
VIN is higher than the first threshold, the
MP5030D's ADJ block beings working. This
sinks a current to adjust the upstream
regulator's output to an accurate 5V. Afterward,
the MP5030D enters a fully working state.
Under Voltage Lockout (UVLO)
UVLO protects the chip from operating at an
insufficient supply voltage. The MP5030D's
second UVLO comparator monitors the input
voltage. Once the input voltage is higher than
the second UVLO threshold, the power
MOSFET starts to turn-on after a fixed delay
with a controlled slew rate.
with an output discharge. Afterward, VBUS
restarts and enters CDP mode.
In DCP mode, the MP5030D can provide power
for the USB devices with protocol autodetection. The MP5030D supports the following
charging schemes:
•

Industry Standard YD/T 1591-2009
•

•
1.2V/1.2V mode
In CDP mode, the MP5030D performs CDP
handshaking with a portable device. The
MP5030D follows the BC1.2 CDP handshaking
specification.
VBUS is always around 5V with current limit and
line drop compensation.

Line Drop Compensation
The MP5030D can compensate for an output
voltage drop, such as high impedance caused
by a long trace, to maintain a fairly constant 5V
load-side voltage. Line drop compensation is
achieved through ADJ. The MP5030D
increases the input voltage by 240mV at an
output of 2.4A (see Figure 2).
ΔVIN

Internal Soft Start (SS)
The internal soft start prevents the output
voltage from overshooting during start-up and
prevents inrush current at the input.

The MP5030D supports DCP and CDP mode
through the MODE pin control. Pull MODE low
to set the USB in CDP mode. Float MODE to
set the USB in DCP mode (see Table 1).

Figure 2: Line Drop Compensation
VADJ sinks a controlled current slowly. The line
drop compensation amplitude linearly increases
as the load current increases.
The MP5030D supports dynamic changing USB
charging modes. For example, when pulling
MODE from floating to logic low, VBUS turns off

MP5030D – USB CHARGING PORT CONTROLLER SUPPORTING CDP AND DCP
In no-load condition, if the input voltage is lower
than 5V (typically), ADJ sinks a current to
regulate the upstream regulator's output voltage
to 5V. If the input voltage is higher than 5V
(typically), MP5030D stops regulating the input
voltage. For a quick load transient response,
ADJ should always be working while the IC is
on. Configure the R1/R2 default output voltage
to be
3.5V, the MP5030D works in constant-current
(CC) limit mode without hiccup. If OCP is
triggered and VOUT < 3.5V for 2ms, the
MP5030D enters hiccup mode. In hiccup mode,
the MP5030D turns off the power MOSFET
(see Figure 4).
