DESCRIPTION The TPS2223A, TPS2224A, and TPS2226A CardBus™ power-interface switches provide an integrated power-management solution for two PC Card sockets. The TPS2220A is a single-slot option for this family of devices. These devices allow the controlled distribution of 3.3 V, 5 V, and 12 V to each card slot. The current-limiting and thermal-protection features eliminate the need for fuses. Current-limit reporting helps the user isolate a system fault. The switch rDS(on) and current-limit values have been set for the peak and average current requirements stated in the PC Card specification, and optimized for cost. A faster maximum current limit response time is the only difference between the TPS2223A, TPS2224A, and TPS2226A and the TPS2223, TPS2224, and TPS2226. Like the TPS2214 and TPS2214A and the TPS2216 and TPS2216A, this family of devices supports independent VPP/VCC switching; however, the standby and interface-mode pins are not supported. Shutdown mode is now supported independently on SHDN as well as in the serial interface. Optimized for lower power implementation, the TPS2223A does not support 12-V switching to VPP. For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. 1 2 3 4 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The idea of add-in cards quickly took hold, and modems, wireless LANs, global positioning satellite system (GPS), multimedia, and hard-disk versions were soon available. As the number of PC Card applications grew, the engineering community quickly recognized the need for a standard to ensure compatibility across platforms. Therefore, the PCMCIA (Personal Computer Memory Card International Association) was established, comprising members from leading computer, software, PC Card, and semiconductor manufacturers. One key goal was to realize the plug-and-play concept, so that cards and hosts from different vendors would be transparently compatible. PC CARD POWER SPECIFICATION System compatibility also means power compatibility. The most current set of specifications (PC Card Standard) set forth by the PCMCIA committee states that power is to be transferred between the host and the card through eight of the 68 terminals of the PC Card connector. This power interface consists of two VCC, two Vpp, and four ground terminals. Multiple VCC and ground terminals minimize connector-terminal and line resistance. The two Vpp terminals were originally specified as separate signals, but are normally tied together in the host to form a single node to minimize voltage losses. Card primary power is supplied through the VCC terminals; flash-memory programming and erase voltage is supplied through the Vpp terminals. Cardbus cards of today typically do not use 12 V, which is now more of an optional requirement in the host. DESIGNING FOR VOLTAGE REGULATION The current PCMCIA specification for output voltage regulation, VO(reg), of the 5-V output is 5% (250 mV). In a typical PC power-system design, the power supply has an output-voltage regulation, VPS(reg), of 2% (100 mV). Also, a voltage drop from the power supply to the PC Card results from resistive losses, VPCB, in the PCB traces and the PCMCIA connector. A typical design would limit the total of these resistive losses to less than 1% (50 mV) of the output voltage. Therefore, the allowable voltage drop, VDS, for the TPS2220A, TPS2223A, TPS2224A, and TPS2226A would be the PCMCIA voltage regulation less the power supply regulation and less the PCB and connector resistive drops: V +V –V –V DS O(reg) PS(reg) PCB Typically, this would leave 100 mV for the allowable voltage drop across the 5-V switch. The specification for output voltage regulation of the 3.3-V output is 300 mV; therefore, using the same equation by deducting the voltage drop percentages (2%) for power-supply regulation and PCB resistive loss (1%), the allowable voltage drop for the 3.3-V switch is 200 mV. The voltage drop is the output current multiplied by the switch resistance of the device. Therefore, the maximum output current, IO max, that can be delivered to the PC Card in regulation is the allowable voltage drop across the IC, divided by the output-switch resistance. V I max + r DS O DS(on) The xVCC outputs have been designed to deliver the peak and average currents defined by the PC Card specification within regulation over the operating temperature range. The xVPP outputs of the device have been designed to deliver 100 mA continuously. OVERCURRENT AND OVERTEMPERATURE PROTECTION PC Cards are inherently subject to damage that can result from mishandling. Host systems require protection against short-circuited cards that can lead to power-supply or PCB trace damage. Even extremely robust systems can undergo rapid battery discharge into a damaged PC Card, resulting in the sudden and unacceptable loss of system power. In comparison, the reliability of fused systems is poor because blown fuses require troubleshooting and repair, usually by the manufacturer. The TPS2220A, TPS2223A, TPS2224A, and TPS2226A take a two-pronged approach to overcurrent protection, which is designed to activate if an output is shorted or when an overcurrent condition is present when switches are powered up. First, instead of fuses, sense FETs monitor each of the xVCC and xVPP power outputs. Unlike Copyright © 2002–2008, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TPS2220A TPS2223A TPS2224A TPS2226A 19 TPS2220A, TPS2223A TPS2224A, TPS2226A www.ti.com SLVS428E – MAY 2002 – REVISED MSRCH 2008 sense resistors or polyfuses, these FETs do not add to the series resistance of the switch; therefore, voltage and power losses are reduced. Overcurrent sensing is applied to each output separately. Excessive current generates an error signal that limits the output current of only the affected output, preventing damage to the host. Each xVCC output overcurrent limits from 1 A to 2.0 A, typically around 1.6 A; the xVPP outputs limit from 100 mA to 250 mA, typically around 200 mA. Second, when an overcurrent condition is detected, the TPS2220A, TPS2223A, TPS2224A, and TPS2226A assert an active low OC signal that can be monitored by the microprocessor or controller to initiate diagnostics and/or send the user a warning message. If an overcurrent condition persists, causing the IC to exceed its maximum junction temperature, thermal-protection circuitry activates, shutting down all power outputs until the device cools to within a safe operating region, which is ensured by a thermal shutdown hysteresis. Thermal limiting prevents destruction of the IC from overheating beyond the package power-dissipation ratings. During power up, the devices control the rise times of the xVCC and xVPP outputs and limit the inrush current into a large load capacitance, faulty card, or connector. 12-V SUPPLY NOT REQUIRED Some PC Card switches use the externally supplied 12 V to power gate drive and other chip functions, which requires that power be present at all times. The TPS2220A, TPS2224A and TPS2226A offer considerable power savings by using an internal charge pump to generate the required higher gate drive voltages from the 3.3-V input. Therefore, the external 12-V supply can be disabled except when needed by the PC Card in the slot, thereby extending battery lifetime. A special feature in the 12-V circuitry actually helps to reduce the supply current demanded from the 3.3-V input. When 12 V is supplied and requested at the VPP output, a voltage selection circuit draws the charge-pump drive current for the 12-V FETs from the 12-V input. This selection is automatic and effectively reduces demand fluctuations on the normal 3.3-V VCC rail. For proper operation of this feature, a minimum 3.3-V input capacitance of 4.7 µF is recommended, and a minimum 12-V input ramp-up rate of 12 V/50 ms (240 V/s) is required. Additional power savings are realized during a software shutdown in which quiescent current drops to a maximum of 1 µA. VOLTAGE-TRANSITIONING REQUIREMENT PC Cards, like portables, are migrating from 5 V to 3.3 V to minimize power consumption, optimize board space, and increase logic speeds. The TPS2220A, TPS2223A, TPS2224A, and TPS2226A meet all combinations of power delivery as currently defined in the PCMCIA standard. The latest protocol accommodates mixed 3.3-V/5-V systems by first powering the card with 5 V, then polling it to determine its 3.3-V compatibility. The PCMCIA specification requires that the capacitors on 3.3-V-compatible cards be discharged to below 0.8 V before applying 3.3-V power. This action ensures that sensitive 3.3-V circuitry is not subjected to any residual 5-V charge and functions as a power reset. PC Card specification requires that VCC be discharged within 100 ms. PC Card resistance cannot be relied on to provide a discharge path for voltages stored on PC Card capacitance because of possible high-impedance isolation by power-management schemes. The devices include discharge transistors on all xVCC and xVPP outputs to meet the specification requirement. SHUTDOWN MODE In the shutdown mode, which can be controlled by SHDN or bit D8 of the input serial DATA word, each of the xVCC and xVPP outputs is forced to a high-impedance state. In this mode, the chip quiescent current is reduced to 1 µA or less to conserve battery power. POWER-SUPPLY CONSIDERATIONS These switches have multiple pins for each 3.3-V (except for TPS2220A) and 5-V power input and for the switched xVCC outputs. Any individual pin can conduct the rated input or output current. Unless all pins are connected in parallel, the series resistance is higher than that specified, resulting in increased voltage drops and power loss. It is recommended that all input and output power pins be paralleled for optimum operation. To increase the noise immunity of the TPS2220A, TPS2223A, TPS2224A, and TPS2226A, the power-supply inputs should be bypassed with at least a 4.7-µF electrolytic or tantalum capacitor paralleled by a 0.047-µF to 20 Submit Documentation Feedback Copyright © 2002–2008, Texas Instruments Incorporated Product Folder Link(s): TPS2220A TPS2223A TPS2224A TPS2226A TPS2220A, TPS2223A TPS2224A, TPS2226A www.ti.com SLVS428E – MAY 2002 – REVISED MSRCH 2008 0.1-µF ceramic capacitor. It is strongly recommended that the switched outputs be bypassed with a 0.1-µF (or larger) ceramic capacitor; doing so improves the immunity of the IC to electrostatic discharge (ESD). Care should be taken to minimize the inductance of PCB traces between the devices and the load. High switching currents can produce large negative voltage transients, which forward biases substrate diodes, resulting in unpredictable performance. Similarly, no pin should be taken below -0.3 V. RESET INPUT To ensure that cards are in a known state after power brownouts or system initialization, the PC Cards should be reset at the same time as the host by applying low-impedance paths from xVCC and xVPP terminals to ground. A low-impedance output state allows discharging of residual voltage remaining on PC Card filter capacitance, permitting the system (host and PC Cards) to be powered up concurrently. The active low RESET input closes internal ground switches S1, S4, S7, and S11 with all other switches left open. The TPS2220A, TPS2223A, TPS2224A, and TPS2226A remain in the low-impedance output state until the signal is de-asserted and further data is clocked in and latched. The input serial data cannot be latched during reset mode. RESET is provided for direct compatibility with systems that use an active-low reset voltage supervisor. The RESET pin has an internal 150-kΩ pullup resistor. CALCULATING JUNCTION TEMPERATURE The switch resistance, rDS(on), is dependent on the junction temperature, TJ, of the die. The junction temperature is dependent on both rDS(on) and the current through the switch. To calculate TJ, first find rDS(on) from Figure 26 through Figure 28, using an initial temperature estimate about 30°C above ambient. Then, calculate the power dissipation for each switch, using the formula: P +r I2 D DS(on) Next, sum the power dissipation of all switches and calculate the junction temperature: ǒȍ Ǔ T + P R )T J D qJA A where: RθJA is the inverse of the derating factor given in the dissipation rating table. Compare the calculated junction temperature with the initial temperature estimate. If the temperatures are not within a few degrees of each other, recalculate using the calculated temperature as the initial estimate. LOGIC INPUTS AND OUTPUTS The serial interface consists of the DATA, CLOCK, and LATCH leads. The data is clocked in on the positive edge of the clock (see Figure 2). The 11-bit (D0-D10) serial data word is loaded during the positive edge of the latch signal. The positive edge of the latch signal should occur before the next positive edge of the clock occurs. The serial interface of the device is compatible with serial-interface PCMCIA controllers. An overcurrent output (OC) is provided to indicate an overcurrent or overtemperature condition in any of the xVCC and xVPP outputs as previously discussed.
