General Description

The AAT4687 OVPSwitch™ is a member of Skyworks'

Application Specific Power MOSFET™ (ASPM™) product

family. It is a P-channel MOSFET power switch with pre-

cise over-voltage protection control, designed to protect

low-voltage systems against high-voltage faults up to

+28V. If the input voltage exceeds the programmed

over-voltage threshold, the P-channel MOSFET switch

will be turned off to prevent the output load circuits from

damage. The AAT4687 is available with an internally

programmed over-voltage trip point or as an adjustable

version programmed by two external resistors.

The AAT4687 includes an under-voltage lockout (UVLO)

protection circuit, which will put the device into sleep

mode at low input voltages only consuming < 1A of

current. The AAT4687 also includes an enable pin (EN)

to enable or disable the device and an OVP, OTP fault

indicator (FLT).

The AAT4687 is offered in a small Pb-free, 10 pin SC70JW

package, and is specified for operation over the -40°C to

+85°C ambient temperature range.

Functional Description

The AAT4687 provides up to 28V over-voltage protection

when powering low-voltage systems such as cell phones,

MP3, and PDAs or when charging Lithium-Ion batteries

from a poorly regulated supply. The AAT4687 is inserted

between the power supply or charger source and the

load to be protected. The AAT4687 IC includes a low

resistance P-channel MOSFET, under-voltage lockout

pro tection, over-voltage monitor, fast shut-down circuit-

ry, and a fault output flag.

In normal operation the P-channel MOSFET acts as a

slew-rate controlled load switch, connecting and discon-

necting the power supply from IN to OUT. A low resis-

tance MOSFET is used to minimize the voltage drop

between the voltage source and the load and to reduce

power dissipation. When the voltage on the input

exceeds the over-voltage protection trip voltage (inter-

nally set in the fixed voltage version or externally by a

voltage divider to the OVP pin for the adjustable ver-

sion), the device immediately turns off the internal

P-channel FET, disconnecting the load from the input and

preventing damage to downstream com ponents.

Simultaneously, the fault flag is raised, alerting the sys-

tem to a problem.

If an over-voltage condition is applied at the time of the

device enable, then the switch will remain OFF.

Under-Voltage Lockout (UVLO)

The AAT4687 has a fixed 3.0V under-voltage lockout

level (UVLO). When the input voltage is less than the

UVLO level, the MOSFET is turned off. 100mV of hyster-

esis is included to ensure circuit stability.

Over-Voltage Protection (OVP)

The AAT4687 adjustable version has a 1.1V ±1.5% over-

voltage trip threshold on the OVP pin. With a resistor

divider on the OVP pin from IN to GND, the over-voltage

trip point can be adjusted anywhere within the input

voltage range (see Table 1). Once the over-voltage trip

level is triggered, the PMOS switch controller will turn off

the PMOS in less than 0.7s.

The AAT4687 fixed version is also available, in which the

resistor divider is internally integrated with the input

voltage trip point at 6.5V. The fixed version of the

AAT4687 does not have a connection to the internal OVP

circuitry and Pin 1 is designed to be left unconnected.

Over-Temperature Protection (OTP)

If the ambient temperature of the device exceeds TSHDN,

the OVP switch is turned off, and the pin is driven low.

The OVP switch will recover automatically when the junc-

tion temperature falls below TSHDN - 20°C.

Fault Indicator (FLT)

The output is an active-low open-drain fault reporting

output. A pull-up resistor should be connected from FLT

to the logic I/O voltage of the host system. FLT will be

asserted immediately if an over-voltage or over-temper-

ature fault occurs.

Enable Control (EN)

EN is an active-low enable input. EN is driven low, con-

nected to ground, or left floating for normal device

operation. Taking the EN high turns off the MOSFET. In

case of an over-voltage or UVLO condition, toggling the

EN will not override the fault condition and the switch will

remain off.

Device Operation

On initial power-up, if VIN < VUVLO or if VOVP > VOVP_TH

(1.1V), the PMOS is held off. If VUVLO < VIN, VOVP < VOVP_TH,

and EN is low, the device enters startup after a 10ms

internal delay.

Application Information

Over-Voltage Protection

The AAT4687 over-voltage protection circuit provides

fast protection against transient voltage spikes and

short duration spikes of high voltage from the power

supply lines. The AAT4687 can quickly disconnect the

input supply from the load and avoid damage to sensi-

tive components.

In portable product applications, if the user removes the

battery pack during charging, this action can create large

transients and a high voltage spike can occur which can

damage other electronic components in the prod uct such

as the battery charger. A "hot plug" of the AC/DC wall

adapter into the AC outlet can create and release a volt-

age spike from the transformer. As a result, some sensi-

tive components within the product can be damaged.

With the AAT4687 placed between the power lines and

the sensitive devices, they are insulated from the voltage

spike and the input supply is disconnected in 0.7s.

Figure 2 shows the over-voltage pro tection response time

of the test circuit (Figure 1) with R1 = 487k, R2 =

110k, COUT = 1F and ROUT = 10. The input volt age is

rapidly increased from 5V to 12V by a voltage surge or

voltage spike. The voltage at the OVP pin is also increased

until it reaches the over-voltage trip point. At this point,

the FLT pin is pulled low and the output voltage starts to

fall. Figure 3 shows a zoom-in scope capture of the OVP

response time; the output is disconnected from the input

in as little as 0.7s.

Adjustable Version -

Over-Voltage Protection Resistors

The over-voltage protection threshold is programmed

with two resistors, R1 and R2. To limit current flow

through the external resistor string while maintaining

good noise immunity, use smaller resistor values, such as

10k for R2. Using a larger value will further reduce sys-

tem current, but will also increase the impedance of the

OVP node, making it more sensitive to external noise and

interference. A suggested value for R2 is 110k. In the

case of R2 = 110k and VOVP_TH = 1.1V, R1 can be

approximated by the following formula:

R1 = · R2 = · 110 - 1

Table 1: Recommended OVP Setting for

Input Capacitor

A 1F or larger capacitor is typically recommended for

CIN. CIN should be located as close to the device VIN pin

as practically possible. Ceramic, tantalum, or aluminum

electrolytic capacitors may be selected for CIN. There is

no specific capacitor equivalent series resistance (ESR)

requirement for CIN. However, for higher current opera-

tion, ceramic capacitors are recommended for CIN due to

their inherent capability over tantalum capacitors to

withstand input current surges from low impedance

sources such as batteries in portable devices.

Capacitors are typically manufactured in different volt age

ratings. If the maximum possible surge voltage is known,

select capacitors with a voltage rating at least 5V higher

than the maximum possible surge voltage. Otherwise,

50V rated capacitors are generally good for most OVP

applications to prevent any surge voltage.

Output Capacitor

A 0.1F~47F output capacitor is required at the output.

Likewise, with the output capac itor, there is no specific

capacitor ESR requirement. COUT may be increased to

accommodate any load transient condition.

Thermal Considerations

and Maximum Output Current

The AAT4687 is designed to deliver a continuous output

load current. The limiting characteristic for maximum

safe operating output load current is package power

dissipation. In order to obtain high operating currents,

careful device layout and circuit operating conditions

must be taken into account. The following discussions

will assume the load switch is mounted on a printed

circuit board utilizing the minimum recommended

footprint as stated in the “Printed Circuit Board Layout

Recommendations” section of this datasheet. At any

given ambient temperature (TA), the maximum package

power dissipation can be determined by the following

equation:

PD(MAX) = TJ(MAX) -TA

θJA

Constants for the AAT4687 are maximum junction

temperature (TJ(MAX) = 125°C) and package thermal

resistance (JA = 160°C/W). Worst-case conditions are

calculated at the maximum operating temperature, TA =

85°C. Typical conditions are calculated under normal

ambient conditions where TA = 25°C. At TA = 85°C,

PD(MAX) = 250mW. At TA = 25°C, PD(MAX) = 625mW.

The maximum continuous output current for the AAT4687

is a function of the package power dissipation and the

RDS of the MOSFET at TJ(MAX). The maximum RDS of the

MOSFET at TJ(MAX) is calculated by increasing the maximum

room temperature.

For maximum current, refer to the following equation:

IOUT(MAX)

PD(MAX)

RDS

The maximum allowable output current for the AAT4687

is 1.8A. If the output current exceeds 1.8A, the device

will be damaged.

Printed Circuit Board

Layout Recommendations

For proper thermal management and to take advantage

of the low RDS(ON) of the AAT4687, certain circuit board

layout rules should be followed: VIN and VOUT should be

routed using wider than normal traces, and GND should

be connected to a ground plane. To maximize package

thermal dissipation and power handling capacity of the

AAT4687 SC70JW-10 package, the ground plane area

connected to the ground pins should be as large as pos-

sible. For best performance, CIN and COUT should be

placed close to the package pins, as shown in Figures 5

and 6.
