MIC2505/2506
Single 2A / Dual 1A / High-Side Switches
General Description
The MIC2505, MIC2505-1, MIC2505-2, and MIC2506 are
single and dual integrated high-side power switches that
consist of TTL compatible control/enable inputs, a charge
pump, and protected N-channel MOSFETs. The MIC2505/6
family can be used instead of separate high-side drivers and
MOSFETs in many low-voltage applications.
The MIC2505/6 family controls voltages ranging from 2.7V to
7.5V. The MIC2505-series can deliver at least 2A continuous
current while the MIC2506 can deliver at least 1A continuous
current from each output. A slow turn-on feature prevents
high inrush current when switching capacitive loads. The
internal control circuitry is powered from the same 2.7V to
7.5V. Within the device’s input range, outputs can be forced
higher than the input voltage when disabled.
Multipurpose open-drain fault flag outputs indicate overcur-
rent limiting, open-load detection (except MIC2505-1 and -2
versions), thermal shutdown, or undervoltage lockout for
each channel.
Overcurrent limiting is internally fixed and requires no exter-
nal components.
Open-load detection is active when the switch is off. When
off, a normal load pulls the output pin low. If the load is open,
an optional, external, high-value resistor pulls the output pin
high, triggering the fault flag. MIC2505-1 and -2 versions are
tailored to Universal Serial Bus (USB) applications and do not
include open-load detection.
Thermal shutdown turns off the output if the die temperature
exceeds approximately 135°C. If enabled, the switch auto-
matically restarts when the temperature falls 10°C.
Undervoltage lockout (UVLO) shuts off the output if the
supply drops below 2.3V typical and reenables the output
when the supply exceeds 2.5V typical.

Functional Description
The MIC2505-series and MIC2506 are high-side N-Channel
switches. The MIC2505, MIC2505-1, and MIC2506 have
active-high enable inputs. The MIC2505-2 has an active-low
input. Fault conditions inhibit output transistor turn-on or
turnoff when enabled.
Control Input
CTL (control input) activates the oscillator, thermal shut-
down, UVLO, 1.2V reference, and gate control circuits. If
there are no fault conditions, the output MOSFET turns on
when enabled.
Reference
A 1.2V bandgap reference supplies a regulated voltage to the
thermal shutdown and undervoltage lockout circuits. The
reference is only active when CTL is enabled.
Oscillator/Charge Pump
The oscillator produces an 80kHz square wave output which
drives the charge pump. The oscillator is enabled when CTL
is active.
The charge pump is a voltage quintupler (5×). The charge
pump capacitors are self contained.
Gate Control
The gate control circuit charges the output MOSFET gate
from the charge pump output or discharges the MOSFET
gate to ground as determined by CTL, thermal shutdown, or
UVLO (undervoltage lockout).
An optional, external capacitor may be connected to the
MIC2505 GATE to lengthen the rise time. This slows the turn
on of the MOSFET output switch. (See MIC2505 Turn-On
Delay graph.) Since this pin connects directly to the MOSFET
gate, use ESD precautions when contacting components
connected to this pin. Leakage resistance may increase turn-
on times.
Input and Output
IN (input) is the supply connection to the logic circuitry and the
drain of the output MOSFET. OUT (output) is the source of the
output MOSFET. In a typical circuit, current flows through the
switch from IN to OUT toward the load.
The output MOSFET and driver circuitry are also designed to
allow the MOSFET source to be externally forced to a higher
voltage than the drain (VOUT > VIN) when the output switch is
off and VIN > UVLO minimum. In this situation, the MIC2505/6
avoids undesirable drain to body diode reverse current flow
by grounding the body when the switch is off. (The conven-
tional method for optimum turn-on threshold has the source
connected to the body. This would allow a large current to flow
when Vsource > Vdrain + 0.6V.)
MIC2505 Series Only
Duplicate IN and OUT leads are not internally connected.
Connect both IN pins to the supply. Connect both OUT leads
to the load.
Thermal Shutdown
Thermal shutdown shuts off the output MOSFET and signals
the fault flag if the die temperature exceeds 135°C. 10°C of
hysteresis prevents the switch from turning on until the die
temperature drops to 125°C.
Overtemperature detection functions only when the control
input is enabled (output MOSFET is on). Both MIC2506
outputs are shut off during overtemperature, and both flags
will go low.
Undervoltage Lockout
UVLO (undervoltage lockout) prevents the output MOSFET
from turning on until VIN (input voltage) exceeds 2.5V typical.
After the switch turns on, if VIN drops below 2.3V typical,
UVLO shuts off the output MOSFET and turns the fault flag
on (active low) until VIN drops below 1.5V.
Undervoltage detection functions only when the control input
is enabled (output MOSFET is on).
Overcurrent Limit
The overcurrent limit is preset internally. The preset level
prevents damage to the output MOSFET but allows a mini-
mum current of 2A through the output MOSFET of the
MIC2505-series and 1A for each output MOSFET of the
MIC2506. Output current is monitored by sensing the voltage
drop across the output MOSFET drain metal resistance.
Overcurrent detection functions only when the control input is
enabled (output MOSFET is on) and VIN is above the UVLO
threshold.
Open-Load Detection
Open-load detection is available only on the MIC2505 and
MIC2506. The open-load detection feature is not included in
the MIC2505-1 or -2 versions.
Open-load detection indicates the absence of an output load
by activating the fault flag. Open-load detection is optional
and is enabled by connecting a high-value pull-up resistor
between IN and OUT. If there is no load, the circuit detects a
high OUT (output) voltage (typically 1V) and signals the fault
flag. Under normal conditions, the low resistance of a typical
load pulls OUT low. Open-load detection functions only when
the control input is low (output MOSFET is off).
Fault Flag
FLG is an N-channel, open-drain MOSFET output. The fault-
flag is active (low) for one or more of the following conditions:
open load (except MIC2505-1 and -2 versions), undervolt-
age, current limit, or thermal shutdown. The flag output
MOSFET is capable of sinking a 10mA load to typically
100mV above ground.

Applications Information
Supply Filtering
A 0.1µF to 1µF bypass capacitor from IN to GND, located at
the device is strongly recommended to control supply tran-
sients. Without a bypass capacitor, an output short may
cause sufficient ringing on the input (from supply lead induc-
tance) to destroy the internal control circuitry.
Input transients must not exceed the absolute maximum
supply voltage (VIN max = 7.5V) even for a short duration.

Figure 1. Supply Bypassing
The bypass capacitor may be omitted only if board design
precautions are followed, such as using extremely short
supply leads or power and ground planes.
Control Input
CTL must be driven logic high or logic low, or be pulled high
or low for a clearly defined input. Floating the input may cause
unpredictable operation. Add a diode clamp if negative spikes
may occur. See Figure 2.
Open-Load Detection
Refer to Typical Applications (first page). Open-load detec-
tion is available only on the MIC2505 and MIC2506. For USB
power distribution applications, the open-load detection fea-
ture is not included in the MIC2505-1 or -2 versions.
The optional open-load detection resistor supplies a small
pull-up current to the load when the output switch is off. (A
100k resistor will draw 50µA from a 5V supply.) Normally, the
load dominates, pulling OUT low. If the load is absent, the
optional resistor pulls OUT high, activating the fault flag if CTL
is off.
When a load is switched off with CTL, capacitance on the
output may cause the open-load function to pull the flag low
until the capacitor is discharged below approximately 2.4V.
Omit the pull-up resistor when open load detection is not
required and for minimum off-state supply current.
Power Bus Switch
The MIC2505/6 family features a MOSFET reverse current
flow prevention circuit. This prevents current from flowing
backwards (from OUT to IN) when CTL is disabled as long as
VIN is above UVLO minimum. In Figure 2, when U1 is on and
U2 is off, this feature prevents current flow from the load (5V)
backward through U2 to the 3.3V supply. (If a discrete
MOSFET and driver were used, the MOSFETs internal body
diode would short the 5V load to the 3.3V supply.)
FLG will be active (low) on any switch that is off whenever the
load voltage is greater than the open load threshold (approxi-
mately 1V) except for MIC2505-1 and MIC2505-2.

Hot Plug-In Applications (Soft-Start)
The MIC2505/6 family can be used to protect the socket-side
and card-side of a supply circuit from transients caused when
a capacitive load is connected to an active supply.
The switch presents a high impedance when off, and slowly
becomes a low impedance as it turns on. This reduces the
inrush current and related voltage drop that result from
charging a capacitive load.

A gate capacitor may be added to the MIC2505 to slow the
turn on time even more, reducing the inrush current. See
MIC2505 Turn-On Delay graph. The UVLO feature insures
that each time the card is removed and VIN = 0 that the gate
of the output switch is discharged to zero volts. A controlled
turn-on is executed each time a board is plugged in, even with
multiple insertions.
