G570 Global Mixed-mode Technology Inc. Dual-Slot PCMCIA/CardBus Power Controller Features Description Fully Integrated VCC and Vpp Switching for Dual The G570 PC Card power-interface switch provides an integrated power-management solution for two PC Cards. All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on a single integrated circuit (IC). The circuit allows the distribution of 3.3V, 5V, and/or 12V card power by means of the Serial interface. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability.

This facilitates low power system designs such as sleep mode and pager mode where only 3.3V is available. The G570 incorporates a reset function, selectable by one of two inputs, to help alleviate system errors. The reset function enables PC card initialization concurrent with host platform initialization, allowing a system reset. Reset is accomplished by grounding the VCC and VPP (flash-memory programming voltage) outputs, which discharges residual card voltage.

Application Information G570 resistance of the switch and thus produce no additional voltage losses. Second, when an overcurrent condition is detected, the G570 asserts a signal at OC that can be monitored by the microprocessor 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, shutting down all power outputs until the device cools to within a safe operating region. Overview PC Cards were initially introduced as a means to add EEPROM (flash memory) to portable computers with limited on-board memory. The idea of add-in cards quickly took hold; modems, wireless LANs, Global Positioning Satellite (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 was established, comprised of members from leading computer, software, PC Card, and semiconductor manufactures. One key goal was to realize the “plug-and play” concept. Cards and hosts from different vendors should be compatible—able to communicate with one another transparently. 12V Supply Not Required Most PC Card switches use the externally supplied 12V VPP power for switch-gate drive and other chip functions, which requires that power be present at all times. The G570 offers considerable power savings by using an internal charge pump to generate the required higher voltages from 5V or 3.3V input; therefore, the external 12V supply can be disable except when needed for flash-memory functions, thereby extending battery lifetime. Do not ground the 12V input if the 12V input is not used. Additional power savings are realized by the G570 during a software shutdown in which quiescent current drops to a typical of 2µA. 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. 3.3V Low Voltage Mode The G570 operates in 3.3V low voltage mode when 3.3V is the only available input voltage (VI(5V)=0).This allows host and PC Cards to be operated in low power 3.3V only modes such as sleep modes or pager modes. Note that in this operation mode, the G570 derives its bias current from the 3.3V input pin and only 3.3V can be delivered to the Card. The 3.3V switch resistance increases, but the added switch resistance should not be critical, because only a small amount of current is delivered in this mode. Overcurrent and Over-Temperature 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. Voltage Transitioning Requirement PC Cards, like portables, are migrating from 5V to 3.3V to minimize power consumption, optimize board space, and increase logic speeds. The G570 is designed to meet all combinations of power delivery as currently defined in the PCMCIA standard. The latest protocol accommodates mixed 3.3V/5V systems by first powering the card with 5V, then polling it to determine its 3.3V compatibility. The PCMCIA specification requires that the capacitors on 3.3V compatible cards be discharged to below 0.8 V before applying 3.3V power. This ensures that sensitive 3.3V circuitry is not subjected to any residual 5V charge and functions as a power reset. The G570 offer a selectable VCC and VPP ground state, in accordance with PCMCIA 3.3V/5V switching specifications, to fully discharge the card capacitors while switching between VCC voltage. The G570 takes a two-pronged approach to overcurrent protection. First, instead of fuses, sense FETs monitor each of the power outputs. Excessive current generates an error signal that linearly limits the output current, preventing host damage or failure. Sense FETs, unlike sense resistors or polyfuses, have an added advantage in that they do not add to the series Ver 1.0 Nov 09, 2000 TEL: 886-3-5788833 http://www.gmt.com.tw 8 Global Mixed-mode Technology Inc. Output Ground Switches Several PCMCIA power distribution switches on the market do not have an active grounding FET switch. These devices do not meet the PC Card specification requiring a discharge of VCC within 100ms. 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. A method commonly shown to alleviate this problem is to add to the switch output an external 100kΩ resistor in parallel with the PC Card. Considering that this is the only discharge path to ground, a timing analysis show that the RC time constant delays the required discharge time to more than 2 seconds. The only way to ensure timing compatibility with PC Card standards is to use a power-distribution switch that has an internal ground switch, like that of the G570, or add an external ground FET to each of the output lines with the control logic necessary to select it. G570 RESET or 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 a low impedance to the VCC and VPP terminals. 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 RESET or RESET input closes internal switches S1, S4, S7, and S10 with all other switches left open (see G570 control logic table). The G570 remains in the low impedance output state until the signal is deasserted and further data is clocked in and latched. RESET or RESET is provided for direct compatibility with systems that use either an active-low or active-high reset voltage supervisor. The unused pin is internally pulled up or down and should be left unconnected. Overcurrent and Thermal Protection The G570 uses sense FETs to check for overcurrent conditions in each of the VCC and VPP 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. When an overcurrent condition is detected, only the power output affected is limited; all other power outputs continue to function normally. The OC indicator, normally a logic high, is a logic low when any overcurrent condition is detected, providing for initiation of system diagnostics and/or sending a warning message to the user. In summary, the G570 is a complete single-chip dual-slot PC Card power interface. It meets all currently defined PCMCIA specifications for power delivery in 5V, 3.3V, and mixed systems, and offers a serial control interface. The G570 offers functionality, power savings, overcurrent and thermal protection, and fault reporting in one 30 pin SSOP surface-mount package for maximum value added to new portable designs. Power Supply Considerations The G570 has multiple pins for each of its 3.3V, 5V, and 12V power inputs and for switched VCC outputs. Any individual pin can conduct the rated input or output current. Unless all pins are connected in parallel, the series resistance is significantly higher than that specified, resulting in increased voltage drops and lost power. Both 12V inputs must be connected for proper VPP switching; it is recommended that all input and output power pins be paralleled for optimum operation. During power up, the G570 controls the rise time of the VCC and VPP outputs and limits the current into a faulty card or connector. If a short circuit is applied after power is established (e.g., hot insertion of a bad card), current is initially limited only by the impedance between the short and the power supply. In extreme cases, as much as 10A to 15A may flow into the short before the current limiting of the G570 engages. If the VCC or VPP outputs are driven below ground, the G570 may latch nondestructively in an off state. Cycling power will reestablish normal operation. Although the G570 is fairly immune to power input fluctuations and noise, it is generally considered good design practice to bypass power supplies typically with a 1µF electrolytic or tantalum capacitor paralleled by a 0.047µF to 0.1µF ceramic capacitor. It is strongly recommended that the switched VCC and VPP outputs be bypassed with a 0.1µF or larger capacitor; doing so improves the immunity of the G570 to electrostatic discharge (ESD). Care should be taken to minimize the inductance of PCB traces between the G570 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 –0.3V. Overcurrent limiting for the VCC outputs is designed to activate, if powered up, into a short in the range of 0.8A to 2.2A. The VPP outputs limit from 120mA to 400mA. The protection circuitry acts by linearly limiting the current passing through the switch rather than initiating a full shutdown of the supply. Shutdown occurs only during thermal limiting. Thermal limiting prevents destruction of the IC from overheating if the package power-dissipation ratings are exceeded. Thermal limiting disables all power outputs (both A and B slots) until the device has cooled. Ver 1.0 Nov 09, 2000 TEL: 886-3-5788833 http://www.gmt.com.tw 9 G570 Global Mixed-mode Technology Inc.
