The devices contain two P-channel MOSFETs that can operate over an input voltage range of 1.62 V to 5.5 V. Each switch is controlled by an on/off input (ON1 and ON2), which is capable of interfacing directly with low-voltage control signals. In TPS22960 a 85-Ω on-chip load resistor is added for output quick discharge when switch is turned off. 7 ON2 6 GND 4 5 VOUT2 W • • GPS Devices Cell Phones/PDAs MP3 Players Digital Cameras EV IE • • • Integrated Dual Load Switch Input Voltage Range: 1.62 V to 5.5 V Low ON-State Resistance – rON = 342 mΩ at VIN = 5.5 V – rON = 435 mΩ at VIN = 3.3 V – rON = 523 mΩ at VIN = 2.6 V – rON = 714 mΩ at VIN = 1.8 V 500-mA Maximum Continuous Switch Current Low Quiescent Current and Shutdown Current Controlled Switch Output Rise Time: 75 µs or 660 µs Integrated Quick Output Discharge Transistor ESD Performance Tested Per JESD 22 – 2000-V Human-Body Model (A114-B, Class II) – 1000-V Charged-Device Model (C101) 8-Pin SOT (DCN) Package: 3 mm × 3 mm 8-Pin µQFN (RSE) Package: 1.5 mm × 1.5 mm PR 1 3 VOUT1 The rise time (slew-rate) of the device is internally controlled in order to avoid inrush current and can be slowed down if needed using the SR pin: TPS22960 feature a 75 µs rise time with the SR pin tied to ground and 660 µs with the SR pin tied to high.

Activating ON continuously holds the switch in the on state so long as there is no fault. ON is active HI and has a low threshold making it capable of interfacing with low voltage signals. The ON pin is compatible with standard GPIO logic threshold. It can be used with any microcontroller with 1.2-V, 1.8-V, 2.5-V, or 3.3-V GPIOs. Input Capacitor To limit voltage drop or voltage transients, a capacitor needs to be placed between VIN and GND. A 1-µF ceramic capacitor, CIN, placed close to the pins is usually sufficient, but higher values of CIN can be used. When switching heavy loads, it is recommended to have an input capacitor about ten times higher than the output capacitor. Output Capacitor Due to the integral body diode in the PMOS switch, a CIN greater than CL is highly recommended. A CL greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN. Board Layout For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT, and GND will help minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance. 18 Submit Documentation Feedback Copyright © 2009, Texas Instruments Incorporated Product Folder Link(s): TPS22960 PACKAGE OPTION ADDENDUM www.ti.com 19-May-2009 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing TPS22960DCNR ACTIVE SOT-23 DCN Pins Package Eco Plan (2) Qty 8 3000 Green (RoHS & no Sb/Br) Lead/Ball Finish CU NIPDAU MSL Peak Temp (3) Level-1-260C-UNLIM (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
