SiP32401A, SiP32402A www.vishay.com Vishay Siliconix 1.1 V to 5.5 V, Slew Rate Controlled Load Switch DESCRIPTION FEATURES SiP32401A and SiP32402A are slew rate controlled load switches designed for 1.1 V to 5.5 V operation. • 1.1 V to 5.5 V operation voltage range The devices guarantee low switch on-resistance at 1.2 V input. They feature a controlled soft-on slew rate of typical 2.5 ms that limits the inrush current for designs of heavy capacitive load and minimizes the resulting voltage droop at the power rails. • Low Ron down to 1.2 V • 62 mΩ typical from 2 V to 5 V • Slew rate controlled turn-on: 2.5 ms at 3.6 V • Fast shutdown load discharge for SiP32402A Available • Low quiescent current < 1 μA when disabled 10.5 μA typical at VIN = 1.2 V These devices feature low voltage control logic interface (On/Off interface) that can interface with low voltage control signal without extra level shifting circuit. SiP32402A also integrates an output discharge switch that enables fast shutdown load discharge. • Reverse current blocking when switch is off Both SiP32401A and SiP32402A have exceptionally low shutdown current and provide reverse blocking to prevent high current flowing into the power source. APPLICATIONS SiP32401A and SiP32402A are in TDFN4 package of 1.2 mm by 1.6 mm. • Notebook / netbook computers • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 • PDAs / smart phones • Tablet PC • Portable media players • Digital camera • GPS navigation devices • Data storage devices • Optical, industrial, medical, and healthcare devices TYPICAL APPLICATION CIRCUIT VIN IN OUT VOUT SiP32401A, SiP32402A C IN 4.7 µF C OUT 0.1 µF EN EN GND GND GND Fig. 1 - SiP32401A, SiP32402A Typical Application Circuit S15-1246-Rev.

DETAILED DESCRIPTION SiP32401A and SiP32402A are advanced slew rate controlled high side load switch consisted of a n-channel power switch. When the device is enable the gate of the power switch is turned on at a controlled rate to avoid excessive in-rush current. Once fully on the gate to source voltage of the power switch is biased at a constant level. The design gives a flat on resistance throughout the operating voltages. When the device is off, the reverse blocking circuitry prevents current from flowing back to input if output is raised higher than input. The reverse blocking mechanism also works in case of no input applied. The SiP32402A also integrates an output discharge switch which allows fast output discharge. APPLICATION INFORMATION Input Capacitor The SiP32401A and SiP32402A do not require an input capacitor. To limit the voltage drop on the input supply caused by transient inrush currents, an input bypass capacitor is recommended. A 2.2 μF ceramic capacitor placed as close to the VIN and GND should be enough. Higher values capacitor can help to further reduce the voltage drop. Ceramic capacitors are recommended for their ability to withstand input current surge from low impedance sources such as batteries in portable devices. Output Capacitor While these devices works without an output capacitor, an 0.1 μF or larger capacitor across VOUT and GND is recommended to accommodate load transient condition. It also help to prevent parasitic inductance forces VOUT below GND when switching off. Output capacitor has minimal affect on device’s turn on slew rate time. There is no requirement on capacitor type and its ESR. S15-1246-Rev. D, 01-Jun-15 Enable The EN pin is compatible with both TTL and CMOS logic voltage levels. Protection Against Reverse Voltage Condition Both SiP32401A and SiP32402A contain reverse blocking circuitry to protect the current from going to the input from the output in case where the output voltage is higher than the input voltage when the main switch is off. Reverse blocking works for input voltage as low as 0 V. Thermal Considerations SiP32401A and SiP32402A are designed to maintain a constant output load current. Due to physical limitations of the layout and assembly of the device the maximum switch current is 2.8 A, as stated in the Absolute Maximum Ratings table. However, another limiting characteristic for the safe operating load current is the thermal power dissipation of the package. To obtain the highest power dissipation (and a thermal resistance of 170 °C/W) the power pad of the device should be connected to a heat sink on the printed circuit board. Figure 23 shows a typical PCB layout. All copper traces and vias for the IN and OUT pins should be sized adequately to carry the maximum continuous current. The maximum power dissipation in any application is dependant on the maximum junction temperature, TJ (max.) = 125 °C, the junction-to-ambient thermal resistance for the TDFN4 1.2 mm x 1.6 mm package, θJ-A = 170 °C/W, and the ambient temperature, TA, which may be formulaically expressed as: P (max.) = T J (max.) - T A θJ- A = 125 - TA 170 Document Number: 63705 9 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 SiP32401A, SiP32402A www.vishay.com It then follows that, assuming an ambient temperature of 70 °C, the maximum power dissipation will be limited to about 324 mW. So long as the load current is below the 2.8 A limit, the maximum continuous switch current becomes a function of two things: the package power dissipation and the RDS(on) at the ambient temperature. As an example let us calculate the worst case maximum load current at TA = 70 °C. The worst case RDS(on) at 25 °C occurs at an input voltage of 1.2 V and is equal to 76 mΩ. The RDS(on) at 70 °C can be extrapolated from this data using the following formula: Vishay Siliconix Recommended Board Layout For the best performance, all traces should be as short as possible to minimize the inductance and parasitic effects. The input and output capacitors should be kept as close as possible to the input and output pins respectively. Connecting the central exposed pad to GND, using wide traces for input, output, and GND help reducing the case to ambient thermal impedance. RDS(on) (at 70 °C) = RDS(on) (at 25 °C) x (1 + TC x DT) Where TC is 4250 ppm/°C. Continuing with the calculation we have RDS(on) (at 70 °C) = 76 mΩ x (1 + 0.00425 x (70 °C - 25 °C)) = 90.5 mΩ The maximum current limit is then determined by P (max.) I LOAD (max.) < R DS(on) which in case is 1.9 A. Under the stated input voltage condition, if the 1.9 A current limit is exceeded the internal die temperature will rise and eventually, possibly damage the device.
