Continuous Current Capability
The MP5090 integrates dual load switches to
provide load protection covering a 0.5V to 5.5V
voltage range. Each channel provides up to
3A/2A of load protection covering a 0.5V to
5.5V voltage range with a 1.85V VCC power
supply. With a small RDS(ON) in a tiny package,
the MP5090 provides a highly efficient and
space-saving solution for notebook, tablet, and
other portable device applications.

With an internal soft-start function, the MP5090
can prevent inrush current during circuit start-up.
The MP5090 also provides internal current limit,
hiccup protection, and thermal shutdown
features. The MP5090 also parallels both
channels easily to double the current capability.

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 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.

MP5090 – LOW IQ, DUAL-CHANNEL, 3A/2A LOAD SWITCH
If the current limit block starts to regulate the
output current, the power loss on the power
OPERATION
The MP5090 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 slew rate of the voltage to the load. The
MP5090 integrates dual load switches. Each
channel can provide 3A of current (for the
MP5090GQHT. The CSP package (MP5090GC)
can provide 2A of load capability. The MP5090
can also easily parallel both channels
connected together to achieve a maximum 6A
load for the MP5090GQHT. The CSP package,
MP5090GC, can achieve 4A if the parallel is
used.
MOSFET causes the IC temperature to rise.
Hiccup protection limits the current for 2ms and
turns it off for another 90ms for the thermal sink.
If the junction temperature rises high enough
during the hiccup on time, thermal shutdown is
triggered. After thermal shutdown, the output is
disabled until the over temperature fault is
removed. The over-temperature threshold is
155°C, and the hysteresis is 30°C.
Output Discharge
The MP5090 has an output discharge function.
The output discharge resistor is active when EN
or VCC is low. This function can discharge Vo
by pulling down the resistance internally when
the IC is disabled and the load is very light.
Enable (EN1, EN2)
When the input voltage is greater than the
under-voltage lockout threshold (UVLO)
(typically 0.5V), and VCC is higher than 1.85V,
the MP5090 can be enabled by pulling EN
above 1.2V. Pull EN to ground to disable the
MP5090. The recommended start-up sequence
is to power up VCC and VIN first. After they are
ready, pull the EN voltage high.
Short-Circuit Protection (SCP)
If the load current increases rapidly due to a
short circuit, the current may exceed the current
limit threshold greatly before the control loop
can respond. If the current reaches an internal
secondary current limit level (about 5A), a fast
turn-off circuit activates to turn off the power
MOSFET. This limits the peak current through
the switch to limit the input voltage drop. The
total short-circuit response time is about 200ns.
Fast off keeps the power MOSFET off for about
80µs before turning it back on.

Parallel Channel Usage
APPLICATION INFORMATION
The MP5090 can be parallel-connected to
achieve a 6A single-load switch for the
MP5090GQHT. The CSP package, MP5090GC,
can achieve 4A (see Figure 3). In this parallel
connection, IN1 is connected to IN2 externally,
and OUT1 is connected to OUT2 externally.
Selecting the VCC Capacitor
VCC is an internal load switch supply voltage to
the control circuitry. Use low ESR capacitors for
the best performance. Ceramic capacitors with
X5R
or
X7R
dielectrics
are
highly
recommended because of their low ESR and
small temperature coefficients. For most
applications, a 1µF capacitor is sufficient.

Selecting the Input and Output Capacitor
The input capacitor is very important for
protecting the part from input voltage spikes
when a dead short or VIN hot-plug occurs. 0805
ceramic capacitors with X5R or X7R dielectrics
are highly recommended because of their low
ESR and small temperature coefficients. For
most applications, a 10µF 0805 input capacitor
and a 1µF 0603 output capacitor are sufficient
for each channel. For high output voltage
applications, a 22µF input capacitor for each
channel is recommended.

Figure 3: Parallel Channel Usage
Reverse Current Block Usage
The dual-channel load switch can be combined
into a single-channel load switch with a reverse
current block function (see Figure 2). IN1 is the
input port, and IN2 is the output port. When
EN1 = EN2 = high, the internal MOSFET is on.
When EN1 = EN2 = low, the internal MOSFET
is off, and the body diode blocks the reverse
current.

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 caps close to the pins.
2. Place enough vias around the IC to achieve
better thermal performance.
