AOZ1320
Load Switch with Controlled Slew Rate
General Description
Features
The AOZ1320 is a P-channel high-side load switch with
controlled slew rate. Three slew rate options are
available. The AOZ1320-01 and AOZ1320-04 have a
slew rate of 1ms, and the AOZ1320-07 has a slew rate of
4.5ms. The AOZ1320-02 and AOZ1320-05 feature fast
Slew Rate (less than 500ns). The slew rate of
AOZ1320-03 and AOZ1320-06 is 100µs. The
AOZ1320-03, AOZ1320-04, AOZ1320-05, and
AOZ1320-07 provide an output discharge circuit to
quickly discharge the output when the switch is disabled.
●
The P-channel MOSFET has typical on resistance of
75mΩ. The very low RDS(ON) significantly reduces the
power path dissipation. The input voltage range of
AOZ1320 is from 1.8V to 5.5V. The control input is
compatible with both TTL and CMOS logic. Ultra low
quiescent current makes this product suitable for any
portable applications.
The AOZ1320 is available in a 6-pin SOT23 or
8-pin 2mm X 2mm DFN package and is rated over
the -40°C to +85°C ambient temperature range.

AOZ1320
Detailed Description
Slew Rate Control
The AOZ1320 is a family of P-channel high-side load
switches with controlled slew rate. The device is enabled
when the input voltage is above the Under-Voltage
Lockout (UVLO) threshold and the EN pin is high. Once
enabled, the gate driver and slew-rate control circuitry
immediately raises the source-to-gate voltage of the
P-channel MOSFET to its threshold level, and then
gradually turns on the MOSFET by linearly increases the
source-to-gate voltage. This slow turn-on action
effectively limits the input inrush current and provides
a nice ramp for the output voltage. After the MOSFET is
fully enhanced, the AOZ1320 quickly increases the
source-to-gate voltage to the full input voltage to
minimize on resistance and reduce power dissipation.
Three slew-rate options are available. AOZ1320-01
and -04 have a slew rate of 1ms, and the AOZ1320-07
has a slew rate of 4.5ms. This option significantly reduces
the inrush current when the MOSFET turns on, allowing
the use of very small input capacitor. AOZ1320-02 and
-05 have no slew rate control and the MOSFET can be
turned on within 500ns. This option is suitable for
applications that require very fast switching. AOZ1320-03
and -06 have a moderate slew rate to 100µs. The
AOZ1320-03, -04, -05, and -07 options include an
internal output discharge circuit that quickly discharges
the output to ground when the device is disabled.
Input Under-Voltage Lockout
The operating voltage range of AOZ1320 is from 1.8V
to 5.5V. An internal UVLO comparator monitors the input
voltage. The device is disabled if the input voltage falls
below the UVLO threshold (0.9V typical). The UVLO
comparator has about 300mV hysteresis.
On/Off Control
The AOZ1320 is enabled when the input voltage is above
the UVLO threshold and the EN pin is asserted high.
The device is disabled when the input voltage is below
the UVLO threshold or the EN pin is asserted low. The
EN input is compatible with both TTL and CMOS logic.
Internal Discharge Resistor
The AOZ1320 has an internal 180Ω resistor to discharge
any remaining voltage from the system to the ground
that is store in a capacitive load. This provides a safe
shutdown of the system to prevent any damages to the
devices. This function is controlled from the Enable pin.
Applications Information
Input Capacitor Selection
Use a 1µF or larger capacitor for input bypassing.
Place the capacitor close to the IN pins of AOZ1320.
Output Capacitor Selection
Use a 0.1µF or larger capacitor between OUT and GND.
The capacitance does not affect the turn-on slew rate.
However, a larger capacitor makes the initial turn-on
transient smoother.
Thermal Considerations
To ensure proper operation, the maximum junction
temperature (TJ(MAX)) of AOZ1320 should not exceed
150°C. Several factors attribute to the junction temperature
rise: load current, MOSFET on resistance (RDS(ON)), onresistance temperature coefficient (TC), junction-to-ambient
thermal resistance (ΘJA), and ambient temperature (TA).
Use the following equation to determine the maximum
continuous load current ILOAD(MAX):
I LOAD ( MAX ) =
T J ( MAX ) – T A
-------------------------------------------------------------------------------------------------------------------Θ JA • R DS ( ON ) • [ 1 + T C • ( T J ( MAX ) – T A ) ]
Rev. 1.6 August 2008
where RDS(ON) is the maximum value of the MOSFET on
resistance at 25°C. Please note the maximum load current
should not exceed the absolute maximum current rating of
the switch. For the SOT-23 package, the absolute maximum current rating is 1.6A. For the 2x2 DFN package, the
absolute maximum current rating is 2.3A.
For example, when VIN = 5V, the maximum continuous
load current of SOT-23 package at room temperature is:
I LOAD ( MAX ) =
150°C – 25°C
---------------------------------------------------------------------------------------------------------------------------------------------- = 2.78A
120°C ⁄ W • 100mΩ • [ 1 + 0.0028 • ( 150°C – 25°C ) ]
Since the calculated current is greater than the absolute
maximum current rating, the maximum load current at
VIN = 5V and room temperature is 1.6A.
Exceeding the maximum continuous load current may
cause damage to the device. Figure 3 and Figure 4 show
the maximum load current as a function of the ambient
temperature for SOT23 and 2x2 DFN packages respectively. To ensure proper operation, the load current should
not exceed the limits in these two figures.

Layout Guidelines
Good PCB is important for improving the thermal performance of AOZ1320. Place the input and output bypass
capacitors close to the IN and OUT pins. The input and
output PCB traces should be as wide as possible for the
given PCB space. Use a ground plane to enhance the
power dissipation capability of the device. The AOZ1320
evaluation board can be used as a layout example. The
PCB layout of AOZ1320 evaluation board is shown in
Figure 5 and 6.

1. Package body sizes exclude mold flash and gate burrs. Mold flash at the non-lead sides should be less than 5 mils each.
2. Dimension “L” is measured in gauge plane.
3. Tolerance ±0.100mm (4 mil) unless otherwise specified.
4. Refer to JEDEC MO-193C AB.
6. Controlling dimension is millimeter. Converted inch dimensions are not necessarily exact.

Notes:
1. Dimensions and tolerances conform to ASME Y14.5M-1994.
2. Controlling dimension is millimeter, converted inch dimensions are not necessarily exact.
3. Dimension b applied to metallized terminal and is measured between 0.10mm and 0.30mm from the terminal tip. If the terminal
has the optional radius on the other end of the terminal, dimension b should not be measured in that radius area.
4. Coplanarity ddd applies to the terminals and all other bottom surface metallization.
