DATA SHEET AAT4631/4631-1 High Power Adjustable Current Limited Load Switch with Fault Flag General Description Features The AAT4631/AAT4631-1 SmartSwitch are high power current limited P-channel MOSFET power switches designed for high side load switching applications. The switches operate with inputs ranging from 2.4V to 5.5V, making them ideal for both 3V and 5V systems. An integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of regulation. Reverse current blocking is provided to protect the load switch from reverse current potentials while the device is shutdown. • • • • The AAT4631/AAT4631-1 are also protected from thermal overload which is limited by power dissipation and junction temperatures. Current limit threshold of AAT4631 is programmed from 500mA to 3.1A with a resistor from SET to ground. The current limit threshold can also be removed to allow up to 3A continuous and 4A peak current to flow through the load switch by shorting the SET pin to ground (This function is the same as AAT4631). The ultra-fast current limit response to a sudden short circuit is a mere 1μs which reduces the requirements of local supply bypassing. An open drain fault flag (FLT) in AAT4631/AAT4631-1 signals an over-current or over-temperature condition after a 5ms blanking time to prevent false reporting. Quiescent current is a low 10μA and the supply current decreases to less than 1μA in shutdown mode. • • • • • • • • • • • 3A Continuous, 4A Peak Current Capability Reverse Blocking During Disable Input Voltage Range: 2.4V to 5.5V Programmable Over-Current Threshold: 500mA to 3.1A (AAT4631-1 only) Fast Transient Response: ▪ 1μs Response to Short Circuit (AAT4631-1 only) Low Quiescent Current ▪ 10μA Typical while Enabled ▪ 1μA Max with Switch Off (TA = 25°C) 90mΩ Typical RDS(ON) Under-Voltage Lockout 5ms Fault Blanking Fault Flag Open Drain Output Active Hi Enable Over-Temperature Protection 1.5ms Soft Start 10 Pin TDFN2222-10 Package Temperature Range: -40°C to +85°C Applications • • • • • Hot Swap Supplies Notebook Computers Portable Products Proprietary Peripheral Ports USB Ports The AAT4631/AAT4631-1 are offered in the small Pb-free, 10-pin TDFN2222-10 package, and are specified for operation over the -40°C to +85°C ambient temperature range.

The devices provide a reverse current blocking feature, ON/OFF enable control, soft start, and a fault flag to notify a system controller of over-current, short-circuit or over-temperature events. The programmable current limit function in AAT4631-1 is intended to protect against short-circuit and over-current events by current limiting to a preset level. In the event of a load current exceeding a user programmed current limit level (ILIM), a high speed current limit loop limits the current in a microsecond and will reset to low impedance once the short-circuit condition is removed. To eliminate startup inrush current, a soft-start block prevents the VOUT from reaching the input voltage level by more than 1ms to limit the inrush current occuring at the input. The AAT4631/AAT4631-1 are internally protected from thermal damage by an over-temperature detection circuit. If the die temperature reaches the internal thermal limit, the power device is switched off until the die temperature cools down to a level below the thermal limit threshold. The devices may operate in a thermal cycling state indefinitely or until the over-current condition is removed.

The ILIM variation is due to processing variations from part to part, as well as variations in the voltages at IN and OUT, plus the operating temperature. Together, these three factors add up to a ±25% tolerance (see ILIM specification in "Electrical Characteristics" section). Figure 1 illustrates a cold device with a statistically higher current limit and a hot device with a statistically lower current limit, both with RSET equal to 1.1kΩ. While the chart, "RSET vs. ILIM" indicates an ILIM of 3A with an RSET of 1.1kΩ, this figure shows that the actual current limit will be at least 2.25A and no greater than 3.75A.

To determine RSET, start with the application required current limit as the minimum current limit value and multiply it by 1.33 to derive the typical current limit value. Next, refer to Table 1 to find the approximate RSET value. For greater precision, use the small current limit range linear approximation to calculate RSET value. For example, for 2.3A current limit requirement, first calculate the typical current limit: 2.3A · 1.33 = 3.059A. Then using table 1, the nearest small current limit range is 3A to 3.1A with 0.1A current limit interval and -0.045kV RSET · ILIM coefficient interval. Then adopt the method of linear approximation in small range to calculate the RSET · ILIM coefficient. 8 (-0.045) · (3.059 - 3) = 3.327 (kV) 0.1 RSET = 3.327kV = 1.087 (kΩ) 3.059A Referring to the standard resistor table, we can select 1.1kΩ ±1% metal film resistor.

Input Capacitor The input capacitor CIN protects the power supply from current transients generated by the load attached to the AAT4631/AAT4631-1. When a short circuit is suddenly applied to the output of the AAT4631/AAT4631-1, a large current limited only by the RDS(ON) of the MOSFET, will flow for less than 1μs before the current limit circuitry activates. In this event, a moderately sized CIN will dramatically reduce the voltage transient seen by the power supply and by other circuitry upstream from the Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 201949B • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • June 4, 2012 DATA SHEET AAT4631/4631-1 High Power Adjustable Current Limited Load Switch with Fault Flag AAT4631/AAT4631-1. The extremely fast short-circuit response time of the AAT4631/AAT4631-1 reduces the size requirement for CIN. CIN should be located as close to the device IN pin as practically possible. Ceramic, tantalum, or aluminum electrolytic capacitors are appropriate 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 In order to insure stability while current limit is active, a low capacitance (approximately 0.47μF) is required. No matter how large the output capacitor, output current is limited to the value set by the AAT4631/AAT4631-1 current limiting circuitry, so very large output capacitors can be used. For example, USB ports are specified to have at least 120μF of capacitance downstream from their controlling power switch. The current limiting circuit will allow an output capacitance of 1000μF or more without disturbing the upstream power supply. Enable Function In many systems, power planes are controlled by integrated circuits which run at lower voltages than the power planes themselves. The enable input (EN) of the AAT4631/AAT4631-1 has low and high threshold voltages that accommodate this condition. The threshold voltages are compatible with 5V TTL and 2.5V to 5V CMOS systems.Both active high and active low options are available for all packages. Connecting to Capacitive Load When switching the AAT4631/AAT4631-1 onto a capacitive load, the AAT4631/AAT4631-1 will charge the output capacitive load at a rate no greater than the current limit setting. FAULT Output The FAULT Flag (FLT) is provided to alert the system if an AAT4631/AAT4631-1 load is not receiving sufficient voltage to operate properly. If current limit or over-temperature circuits in any combination are active for more than approximately 5ms, the FAULT Flag is pulled to ground through an approximately 100Ω resistor. The filtering of voltage or current transients of less than 4ms prevents capacitive loads connected to the AAT4631/AAT4631-1 output from activating the FAULT Flag when they are initially attached. Pull-up resistances of 1kΩ to 100kΩ are recommended. Since FLT is an open drain terminal, it may be pulled up to any unrelated voltage less than the maximum operating voltage of 5.5V, allowing for level shifting between circuits. Thermal Considerations Since the AAT4631/AAT4631-1 have internal current limit and over-temperature protection, junction temperature is rarely a concern. However, if the application requires large currents in a hot environment, it is possible that temperature, rather than current limit, will be the dominant regulating condition. In these applications, the maximum current available without risk of an overtemperature condition must be calculated. The maximum internal temperature while current limit is not active can be calculated using Equation 1. TJ(MAX) = I2MAX · RDS(ON)(MAX) · RθJA + TA(MAX) where IMAX is the maximum current required by the load. RDS(ON)(MAX) is the maximum rated RDS(ON) of the AAT4631/ AAT4631-1 at high temperature. RθJA is the thermal resistance between the AAT4631/AAT4631-1 die and the board onto which it is mounted. TA(MAX) is the maximum temperature that the PCB under the AAT4631/AAT46311 would be if the AAT4631/AAT4631-1 were not dissipating power. The following equation can be rearranged to solve for IMAX. IMAX = TSD(MIN) - TA(MAX) RDS(ON)(MAX) ∙ RθJA where TSD(MIN) is the minimum temperature required to activate AAT4631/AAT4631-1's over-temperature protection. With the typical specification of 140°C, 115°C is a safe minimum value to use. For example, if an application is specified to operate in 50°C environments, the PCB operates at temperatures as high as 85°C. The application is sealed and its PCB is small, causing RθJA to be approximately 72.43°C/W. Using the following equation: IMAX = 115 - 85 = 1.66(A) 0.15 · 72.43 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 201949B • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • June 4, 2012 9 DATA SHEET AAT4631/4631-1 High Power Adjustable Current Limited Load Switch with Fault Flag Evaluation Board The PCB layout is shown in Figures 3 and 4.
