The AAT4280A is a P-channel MOSFET power switch designed for high-side load switching applications. The device has a typical RDS(ON) of 80mW, allowing increased load switch power handling capacity. The device is available in three different versions with flexible turn-on and turn-off characteristics - from very fast to slew rate limited. The standard AAT4280A (-1) version has a slew rate limited turn-on load switch and is functionally compatible with the AAT4250 device, while offering superior RDS(ON) characteristics. The AAT4280A (-2) version features fast load switch turn-on capabilities, typically less than 500ns turn-on and 3µs turn-off times. The AAT4280A (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. The AAT4280A (-4) version features the slowest load switch turn-on capability, typically greater than 4.0ms turn-on time. All AAT4280A load switch versions operate with an input voltage ranging from 1.5V to 5.5V, making them ideal for both 3V and 5V systems. Input logic levels are TTL and 2.5V to 5V CMOS compatible. The quiescent supply current is very low, typically 25nA. • 1.5V to 5.5V Input Voltage Range • Very Low RDS(ON), Typically 80mW (5V) • Slew Rate Limited Turn-On Time Options ▪4.5ms ▪1ms ▪0.5µs ▪100µs • Fast Shutdown Load Discharge Option • Low Quiescent Current ▪ 25nA (typ) • TTL/CMOS Input Logic Level • Temperature Range: -40ºC to +85°C • 3kV ESD Rating • SC70JW-8, SOT23-6, and WLCSP-5 Packages The AAT4280A is available in the Pb-free 8-pin SC70JW, 6-pin SOT23, and WLCSP-5 packages and is specified over the -40°C to +85°C temperature range.

There are three versions of the AAT4280A with different turn-on and turn-off characteristics to choose from, depending upon the specific requirements of an application. The first version, the AAT4280A-1, has a moderate turn-on slew rate feature, which reduces inrush current when the MOSFET is turned on. This function allows the load switch to be implemented with either a small input capacitor or no input capacitor at all. During turn-on slewing, the current ramps linearly until it reaches the level required for the output load condition. The proprietary turn-on current control method works by careful control and monitoring of the MOSFET gate voltage. When the device is switched ON, the gate voltage is quickly increased to the threshold level of the MOSFET. Once at this level, the current begins to slew as the gate voltage is slowly increased until the MOSFET becomes fully enhanced. Once it has reached this point, 10 the gate is quickly increased to the full input voltage and RDS(ON) is minimized. The second version, the AAT4280A-2, is a very fast switch intended for high-speed switching applications. This version has no turn-on slew rate control and no special output discharge features. The third switch version, the AAT4280A-3, has the addition of a minimized slew rate limited turn-on function and a shutdown output discharge circuit to rapidly turn off a load when the load switch is disabled through the ON/OFF pin. The final switch version, the AAT4280A-4, features a very slow turn-on slew rate with a typical value of 4.5ms for LCD panel applications. All versions of the AAT4280A operate with input voltages ranging from 1.5V to 5.5V. All versions of this device have extremely low operating current, making them ideal for battery-powered applications. The ON/OFF control pin is TTL compatible and will also function with 2.5V to 5V logic systems, making the AAT4280A an ideal level-shifting load switch.

A CIN capacitor is not required for basic operation; however, CIN is useful in preventing load transients from affecting upstream circuits. 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 ESR requirement for CIN; however, for higher current operation, 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. Output Capacitor For proper slew operation, a 0.1µF capacitor or greater between VOUT and GND is recommended. The output capacitor has no specific capacitor type or ESR requirement. If desired, COUT may be increased without limit to accommodate any load transient condition without adversely affecting the device turn-on slew rate time. Enable Function The AAT4280A features an enable / disable function. This pin (ON/OFF) is compatible with both TTL or CMOS logic. Reverse Output-to-Input Voltage Conditions and Protection Under normal operating conditions, a parasitic diode exists between the output and input of the load switch. The input voltage should always remain greater than the output load voltage, maintaining a reverse bias on the internal parasitic diode. Conditions where VOUT might exceed VIN should be avoided since this would forward bias the internal parasitic diode and allow excessive current flow into the VOUT pin and possibly damage the load switch. In applications where there is a possibility of VOUT exceeding VIN for brief periods of time during normal operation, the use of a larger value CIN capacitor is highly recommended. A larger value of CIN with respect to COUT will effect a slower CIN decay rate during shutdown, thus preventing VOUT from exceeding VIN. In applications where there is a greater danger of VOUT exceeding VIN for extended periods of time, it is recommended to place a Schottky diode from VIN to VOUT (connecting the cathode to VIN and anode to VOUT). The Schottky diode forward voltage should be less than 0.45V. Thermal Considerations and High Output Current Applications The AAT4280A 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 need to 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 Layout Considerations 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 AAT4280A are maximum junction temperature, TJ(MAX) = 125°C, and package thermal resistance, θJA = 120°C/W. Worst case conditions are calculated at the maximum operating temperature where TA = 85°C. Typical conditions are calculated under normal ambient conditions where TA = 25°C. At TA = 85°C, PD(MAX) = 333mW. At TA = 25°C, PD(MAX) = 833mW. The maximum continuous output current for the AAT4280A 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 RDS by the RDS temperature coefficient. The temperature coefficient (TC) is 2800ppm/°C. Therefore, MAX RDS125°C = RDS25°C · (1 + TC · DT) MAX RDS125°C = 120mW · (1 + 0.0028 · (125°C - 25°C)) = 154mW For maximum current, refer to the following equation: IOUT(MAX) < PD(MAX) RDS Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 202230A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • July 31, 2012 11 DATA SHEET AAT4280A Slew Rate Controlled Load Switch For example, if VIN = 5V, RDS(MAX) = 154mW and TA = 25°C, IOUT(MAX) = 2.3A. If the output load current were to exceed 2.3A or if the ambient temperature were to increase, the internal die temperature would increase and the device would be damaged. Higher peak currents can be obtained with the AAT4280A. To accomplish this, the device thermal resistance must be reduced by increasing the heat sink area or by operating the load switch in a duty-cycle manner. High Peak Output Current Applications Some applications require the load switch to operate at a continuous nominal current level with short duration, high-current peaks. The duty cycle for both output current levels must be taken into account. To do so, first calculate the power dissipation at the nominal continuous current level, and then add in the additional power dissipation due to the short duration, high-current peak scaled by the duty factor. For example, a 4V system using an AAT4280A operates at a continuous 100mA load current level and has short 2A current peaks, as in a GSM application. The current peak occurs for 576µs out of a 4.61ms period. First, the current duty cycle is calculated: % Peak Duty Cycle: X/100 = 576µs/4.61ms % Peak Duty Cycle = 12.5% The load current is 100mA for 87.5% of the 4.61ms period and 2A for 12.5% of the period. Since the Electrical Characteristics do not report RDS(MAX) for 4V operation, it must be calculated approximately by consulting the chart of RDS(ON) vs. VIN. The RDS reported for 5V can be scaled by the ratio seen in the chart to derive the RDS for a 4V VIN: 120mW · 87mW /80mW = 130mW. De-rated for temperature: 130mW · (1 + 0.0028 · (125°C - 25°C)) = 166mW. The power dissipation for a 100mA load is calculated as follows: PD(MAX) = IOUT2 · RDS PD(100mA) = (100mA)2 · 166mW PD(100mA) = 1.66mW PD(87.5%D/C) = %DC · PD(100mA) PD(87.5%D/C) = 0.875 · 1.66mW PD(87.5%D/C) = 1.45mW The power dissipation for 100mA load at 87.5% duty cycle is 1.45mW. Now the power dissipation for the remaining 12.5% of the duty cycle at 2A is calculated: PD(MAX) = IOUT2 · RDS PD(2A) = (2A)2 · 166mW PD(2A) = 664mW PD(12.5%D/C) = %DC · PD(2A) PD(12.5%D/C) = 0.125 · 664mW PD(12.5%D/C) = 83mW The power dissipation for 2A load at 12.5% duty cycle is 83mW. Finally, the two power figures are summed to determine the total true power dissipation under the varied load: PD(total) = PD(100mA) + PD(2A) PD(total) = 1.45mW + 83mW PD(total) = 84.5mW The maximum power dissipation for the AAT4280A operating at an ambient temperature of 85°C is 333mW. The device in this example will have a total power dissipation of 84.5mW. This is well within the thermal limits for safe operation of the device; in fact, at 85°C, the AAT4280A will handle a 2A pulse for up to 50% duty cycle. At lower ambient temperatures, the duty cycle can be further increased. Printed Circuit Board Layout Recommendations For proper thermal management and to take advantage of the low RDS(ON) of the AAT4280A, a few 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 dispation and power handling capacity of the AAT4280A SC70JW-8 package, the ground plane area connected to the ground pins should be made as large as possible. For best performance, CIN and COUT should be placed close to the package pins.
