DATA SHEET AAT4282A Slew Rate Controlled Load Switch General Description Features The AAT4282A SmartSwitch™ is a member of Skyworks' Application Specific Power MOSFET (ASPM™) product family. The AAT4282A is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 60m, allowing increased load switch current handling capacity with a low forward voltage drop. 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 4282A (-1) version has a slew-rate limited turn-on load switch. The AAT4282A (-2) version features fast turn-on capability, typically less than 500ns turn-on and 3μs turn-off times. The AAT4282A (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. An additional feature is a slew-rate selector pin which can switch between fast and slow slew rate. • VIN Range: 1.5V to 6.5V • Low RDS(ON) ▪ 60m Typical @ 5V ▪ 140m Typical @ 1.5V • Slew Rate Turn-On Time Options ▪ 1ms ▪ 0.5μs ▪ 100μs • Fast Shutdown Load Discharge Option • Low Quiescent Current ▪ Typically 1μA • TTL/CMOS Input Logic Level • Temperature Range -40°C to 85°C • FTDFN22-8 and SC70JW-8 Packages Applications • • • • • • • • All the AAT4282A load switch versions are designed to operate from 1.5V up to 6.5V, making them ideal for both 3V and 5V systems.

Functional Description The AAT4282A is a family of flexible dual P-channel MOSFET power switches designed for high-side load switching applications. There are three versions of the AAT4282A with different turn-on and turn-off characteristics to choose from, depending upon the specific requirements of an application. The first version, the AAT4282A-1, has a moderate turn-on slew rate feature, which reduces in-rush 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 8 reached this point the gate is quickly increased to the full input voltage and the RDS(ON) is minimized. The second version, the AAT4282A-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 final switch version, the AAT4282A-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. Using the FAST input pin on the AAT4282A-3, the device can be manually switched to a slower slew rate. All versions of the AAT4282A operate with input voltages ranging from 1.5V to 6.5V. 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 AAT4282A an ideal level-shifting load switch.

A CIN capacitor is not required for basic operation; however, it 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 equivalent series resistance (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 is required between VOUT and GND. Likewise, with the output capacitor, there is no specific capacitor ESR requirement. If desired, COUT may be increased without limit to accommodate any load transient condition without adversely affecting the slew rate. Enable Function The AAT4282A features an enable / disable function. This pin (ON) is active high and is compatible with TTL or CMOS logic. To assure the load switch will turn on, the ON control level must be greater than 1.4V. The load switch will go into shutdown mode when the voltage on the ON pin falls below 0.4V. When the load switch is in shutdown mode, the OUT pin is tri-stated, and quiescent current drops to leakage levels below 1μA. 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 cur- rent flow into the VOUT pin, possibly damaging 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 AAT4282A 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 AAT4282A are maximum junction temperature (TJ(MAX) = 125°C)1 and package thermal resistance (JA = 70°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) = 571mW. At TA = 25°C, PD(MAX) = 1429mW. The maximum continuous output current for the AAT4282A 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 1. The actual maximum junction temperature of AAT4282A is 150°C. However, good design practice is to derate the maximum die temperature to 125°C to prevent the possibility of over-temperature damage.

The temperature coefficient (TC) is 2800ppm/°C. Therefore, at 125°C: RDS(MAX) = RDS(25°C) · (1 + TC · T) RDS(MAX) = 130m · + 0.002800 · (125°C - 25°C)) RDS(MAX) = 166.4m For maximum current, refer to the following equation: IOUT(MAX) < PD(MAX) RDS For example, if VIN = 5V, RDS(MAX) = 166.4m, and TA = 25°C, IOUT(MAX) = 2.93A. If the output load current were to exceed 2.93A 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 AAT4282A. 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. Duty cycles with peaks less than 2ms in duration can be considered using the method described in the High Peak Current Applications section of this datasheet. 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. Refer to the IDM specification in the Absolute Maximum Ratings table to ensure the AAT4282A’s maximum pulsed current rating is not exceeded. 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 the additional power dissipation due to the short duration, high-current peak scaled by the duty factor. For example, a 4V system using an AAT4282A which has channel A operates at a continuous 1A load current level, and channel B operates at a continuous 100mA load current level and has short 3A 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: ⎛ x ⎞ ⎛ 576μs ⎞ % Peak Duty Cycle = ⎝ 100⎠ = ⎝ 4.61ms⎠ % Peak Duty Cycle = 12.5% The load current is 100mA for 87.5% of the 4.61ms period and 3A for 12.5% of the period. Since the 10 Electrical Characteristics do not report RDS(MAX) for 4V operation, it must be approximated by consulting the chart of RDS(ON) vs. VIN. The RDS reported for 5V at 100mA and 3A can be scaled by the ratio seen in the chart to derive the RDS for 4V VIN at 25°C: 130m · 63m/60m = 136.5m. De-rated for temperature: 136.5m · (1 + 0.002800 · (125°C - 25°C)) = 174.7mΩ. For channel A, the power dissipation for a continuous 1A load is calculated as follows: PD(CHA) = IOUT2 · RDS = (1A)2 · 174.7m = 174.7mW For channel B, the power dissipation for 100mA load is calculated as follows: PD(MAX) = IOUT2 · RDS PD(100mA) = (100mA)2 · 174.7m PD(100mA) = 1.75mW PD(87.5%D/C) = %DC · PD(100mA) PD(87.5%D/C) = 0.875 · 1.75mW PD(87.5%D/C) = 1.53mW The power dissipation for 100mA load at 87.5% duty cycle is 1.53mW. Now the power dissipation for the remaining 12.5% of the duty cycle at 3A is calculated: PD(MAX) = IOUT2 · RDS PD(3A) = (3A)2 · 174.7m PD(3A) = 1572mW PD(12.5%D/C) = %DC · PD(3A) PD(12.5%D/C) = 0.125 · 1572mW PD(12.5%D/C) = 196.7mW Finally, the total power dissipation for channels A and B is determined as follows: PD(total) = PD(CHA) + PD(100mA) + PD(3A) PD(total) = 174.7mW + 1.53mW + 196.7mW PD(total) = 373mW The maximum power dissipation for the AAT4282A operating at an ambient temperature of 85°C is 373mW. The device in this example will have a total power dissipation of 571mW. This is well within the thermal limits for safe operation of the device; in fact, at 85°C, the AAT4282A will handle a 3A pulse for up to 25% duty cycle. At lower ambient temperatures, the duty cycle can be further increased.
