All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on single integrated circuits. These low-cost devices allow the distribution of 3.3-V, 5-V, and/or 12-V power to the card. The current-limiting feature eliminates the need for fuses. Current-limit reporting can help the user isolate a system fault. The TPS2214A and TPS2216A feature a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5-V power. This feature facilitates low-power system designs such as sleep modes where only 3.3 V is available. These devices also have the ability to program the xVPP outputs independent of the xVCC outputs. A standby mode that changes all output-current limits to 50 mA (typical) has been incorporated. End-equipment applications for these products include: notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and bar-code scanners. The TPS2216A is backward-compatible with the TPS2202A, TPS2206, and TPS2216. The TPS2214A is backward-compatible with the TPS2214.

Cards were initially introduced as a means to add EEPROM (flash memory) to portable computers with limited onboard memory. The idea of add-in cards quickly took hold; 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. To this end, the PCMCIA (Personal Computer Memory Card International Association), comprising members from leading computer, software, PC Card, and semiconductor manufacturers, was established. One key goal was to realize the plug-and-play concept. Cards and hosts from different vendors should be compatible or able to communicate with one another transparently. 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 commonly 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. 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 will result 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 TPS2214A or TPS2216A would be the PCMCIA voltage regulation less the power supply regulation and less the PCB and connector resistive drops: V DS +V O(reg) –V PS(reg) –V 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; so, 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 TPS2214A or TPS2216A. 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 can deliver 1 A continuously at 5 V and 3.3 V within regulation over the operating temperature range. The xVPP outputs of the IC can deliver 200 mA continuously. 18 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265                SLVS267C − DECEMBER 1999 − REVISED FEBRUARU 2008 APPLICATION INFORMATION designing for voltage regulation (continued) 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 could lead to power-supply or PCB trace damage. Even systems robust enough to withstand a short circuit would still undergo rapid battery discharge into the damaged PC Card, resulting in the rather sudden and unacceptable loss of system power. Most hosts include fuses for protection. However, the reliability of fused systems is poor, as blown fuses require troubleshooting and repair, usually by the manufacturer. The TPS2214A and TPS2216A 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 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 2.2 A, typically around 1.6 A; the xVPP outputs limit from 250 mA to 500 mA, typically around 375 mA. Second, when an overcurrent condition is detected, these devices 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. In the event that an overcurrent condition persists, causing the IC to exceed its maximum junction temperature, thermal-protection circuitry activates. This shuts down all power outputs until the device cools to within a safe operating region, which is ensured by a thermal shutdown hysteresis. 12-V supply not required Many PC Card switches use the externally supplied 12 V to power gate drive and other chip functions; this requires that power be present at all times. The TPS2214A and TPS2216A offer considerable power savings by using an internal charge pump to generate the required higher gate drive voltages from the 5-V or 3.3-V power supplies. Therefore, the external 12-V supply can be disabled except when needed for flash-memory functions, thereby extending battery lifetime. Additional power savings are realized by the IC during shutdown mode, in which quiescent current drops to a maximum of 1 µA. 3.3-V low-voltage mode The TPS2214A and TPS2216A will operate in 3.3-V low-voltage mode when 3.3 V is the only available input voltage (VI(5V) = 0, VI(12V) = 0). This feature allows host and PC Cards to be operated in low-power 3.3-V-only modes such as sleep modes. Note that in this operation mode, the IC will derive its bias current from the 3.3-V input pin and can only provide 3.3 V to the outputs. voltage transitioning requirement PC Cards are migrating from 5 V to 3.3 V to minimize power consumption, optimize board space, and increase logic speeds. The TPS2214A and TPS2216A 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 can not 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 TPS2214A and TPS2216A include discharge transistors on all xVCC and xVPP outputs to meet the specification requirement.

In this mode, the chip quiescent current is limited to 1 µA or less to conserve battery power. standby mode The TPS2214A and TPS2216A can be put in standby mode by pulling STBY low to conserve power during low-power operation. In this mode, all of the power outputs (xVCC and xVPP) will have a nominal current limit of 50 mA. STBY has an internal 150-kΩ pullup resistor. The output-switch status of the device must be set, allowing the output capacitors to charge, prior to enabling the standby mode. Changing the setting of the output switches with the device in standby mode may cause an overcurrent response to be generated. mode The mode pin programs the switches in either TPS2214A/ TPS2216A or TPS2206 mode. An internal 150-kΩ pulldown resistor is connected to the pin. Floating or pulling the mode pin low sets the switches in TPS2206 mode; pulling the mode pin high sets the switches in TPS2214A/ TPS2216A mode. In TPS2206 mode, xVPP outputs are dependent on xVCC outputs. In TPS2214A/TPS2216A mode, xVPP is programmed independent of xVCC. Refer to TPS2214A/TPS2216A control-logic tables for more information. power-supply considerations The TPS2214A and TPS2216A have multiple pins for each of its 3.3-V and 5-V power inputs 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 less power. It is recommended that all input and output power pins be paralleled for optimum operation. Because the two 12-V pins are not internally connected, they must be tied together externally. To increase the noise immunity of the TPS2214A and TPS2216A, the power-supply inputs should be bypassed with a 1-µF electrolytic or tantalum capacitor paralleled by a 0.047-µF to 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 IC 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, or allowed to fall, below −0.3 V. RESET and RESET inputs 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-high RESET or active low RESET input will close internal switches S1, S4, S7, and S11 with all other switches left open. The TPS2214A and TPS2216A remain in the low-impedance output state until the signal is deasserted and further data is clocked in and latched. The input serial data can not be latched during reset mode. RESET and RESET are provided for direct compatibility with systems that use either an active-low or active-high reset voltage supervisor. The RESET pin has an internal 150-kΩ pulldown resistor and the RESET pin has an internal 150-kΩ pullup resistor. The device will be reset automatically when powered up. 20 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265                SLVS267C − DECEMBER 1999 − REVISED FEBRUARU 2008 APPLICATION INFORMATION 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 Figures 23 through 25, using an initial temperature estimate about 50°C above ambient. Then calculate the power dissipation for each switch, using the formula: P D +r DS(on) I2 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 DATA, CLOCK, and LATCH leads. The data is clocked in on the positive edge of the clock (see Figures 2 and 3). 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 TPS2216 serial interfaces are compatible with serial-interface PCMCIA controllers and current PCMCIA and Japan Electronic Industry Development Association (JEIDA) standards. An overcurrent output (OC) is provided to indicate an overcurrent or overtemperature condition in any of the xVCC and xVPP outputs as previously discussed.

Detailed Interconnections and Capacitor Recommendations POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 23                SLVS267C − DECEMBER 1999 − REVISED FEBRUARU 2008 APPLICATION INFORMATION 12-V flash memory supply The TPS6734 is a fixed 12-V output boost converter capable of delivering 120 mA from inputs as low as 2.7 V. The device is pin-for-pin compatible with the MAX734 regulator and offers the following advantages: lower supply current, wider operating input-voltage range, and higher output currents. As shown in Figure 33, the only external components required are: an inductor, a Schottky rectifier, an output filter capacitor, an input filter capacitor, and a small capacitor for loop compensation. The entire converter occupies less than 0.7 in2 of PCB space when implemented with surface-mount components. An enable input is provided to shut the converter down and reduce the supply current to 3 µA when 12 V is not needed. The TPS6734 is a 170-kHz current-mode PWM (pulse-width modulation) controller with an n-channel MOSFET power switch. Gate drive for the switch is derived from the 12-V output after start-up to minimize the die area needed to realize the 0.7-Ω MOSFET and improve efficiency at input voltages below 5 V. Soft start is accomplished with the addition of one small capacitor. A 1.22-V reference (pin 2) is brought out for external use. For additional information, see the TPS6734 data sheet (SLVS127).
