MIC2564A
Dual Serial PCMCIA/CardBus Power Controller Preliminary Information
General Description
The MIC2564A is dual-slot PC Card (PCMCIA) and CardBus power controller. It is a sophisticated power switching matrix that controls VCC and VPP voltages to two PC Card slots. The MIC2564A is used in conjunction with a serial-data output logic controller using the standard three-wire serial control data format. When connected to 3.3V, 5V, and 12V system power supplies, the MIC2564A can switch its VCC outputs between 0V, 3.3V, 5.0V, and high-impedance states and VPP outputs between 0V, 3.3V, 5V, 12V, and high-impedance states. The VCC outputs will supply a minimum of 1A current to the socket and the VPP outputs will supply a minimum of 120mA to the socket. Voltage rise and fall times are well controlled. The MIC2564A also features an efficient standby (sleep) mode at 0.3A typical quiescent current. 12V and 5V supplies are not required for MIC2564A operation making it possible to omit one or both supplies when they are not needed by the system. An internal charge pump supplies the internal bias voltages required for high-performance switching. The MIC2564A is protected by overtemperature shutdown, and protects itself and the system with current limiting and cross-conduction lockout. The MIC2564A is available in 24-pin SSOP and 24-pin TSSOP.

The device is not guaranteed to function outside its operating rating. Devices are ESD sensitive. Handling precautions recommended. Output enabled into short circuit. Measurement is from the 50% point of the SLA rising edge. Measurement is from the Hi-Z- or 0V-state command to the beginning of the slope. Measurement does not apply when device is in current limit or thermal shutdown. VCC3 IN powers all internal logic, bias, and drive circuitry, and is required for operation. VPP and VCC5 IN are not required for operation. VPP IN must be either high impedance or greater than or approximately equal to the highest voltage VCC in the system.

MIC2564A
MIC2564A
Micrel
If no card is inserted, or the system is in sleep mode, the logic controller commands the MIC2564A to shut down VCC. This also places the switch into a shutdown (sleep) mode, where current consumption drops to nearly zero, with only tiny CMOS leakage currents flowing. Internal device control logic, MOSFET drive and bias voltage is powered from VCC3 IN. The high voltage bias is generated by an internal charge pump multiplier. Input logic threshold voltages are compatible with common PC Card logic controllers using either 3.3V or 5V supplies.
Applications Information
PC Card power control for two sockets is easily accomplished using the MIC2564A PC Card/CardBus power controller. Control commands from a three-wire (plus Reset) serial bus determine VCC and VPP output voltages and select standby or operate mode. VCC outputs of 3.3V and 5V at the maximum allowable PC Card current are supported. The VCC outputs also support GND (0V) and high-impedance states. The VPP outputs support VPP (12V), VCC voltages (3.3V or 5V), GND (0V), or high impedance. When the VCC = Hi-Z (high impedance) condition is selected, the device switches into sleep mode and draws only leakage current. Full protection during hot switching is provided which prevents feedback from the VCC output (for example, from the 5V supply into the 3.3V supply) by locking out the low voltage switch until the initial switch's gate voltage drops below 0.7V. MIC2564A internal logic and MOSFET drive circuitry is powered from the VCC3 input and internal charge-pump voltage multipliers. Switching speeds are carefully controlled to prevent damage to sensitive loads and meet all PC Card Specification timing requirements, including those for the CardBus option. Supply Bypassing The MIC2564A is a switch and has no stability problems; however, supply bypass capacitors are recommended to reduce inductive transients and improve output ripple. As all internal device logic and comparison functions are powered from the VCC3 input, the power supply quality on this line is the most important. Micrel recommends placing 1F surfacemount ceramic (low ESR) capacitors from VCC3 IN and VCC5 IN pins to ground and two 0.1F surface-mount ceramic capacitors, one from each VPP IN pin, to ground. Also, the VCC OUT and VPP OUT pins may use 0.01F to 0.1F capacitors for noise reduction and to reduce the chance of ESD (electrostatic discharge) damage. Power Status Feedback (Flags) Two flag outputs monitor the VCC and VPP output voltages on both slot A and B, falling low when the voltage is not proper. Use of these open-drain flag outputs is optional; if they are used, a pull-up resistor to either the 3.3V or 5V supply is required. Unused flag outputs may be left open. PC Card Slot Implementation The MIC2564A is designed for full compatibility with the Personal Computer Memory Card International Association (PCMCIA) PC Card Specification including the CardBus and Zoom Video (ZV) options. When a PC card is initially inserted, it should receive VCC (3.3V 0.3V or 5.0V 5%). The initial voltage is determined by a combination of mechanical socket keys and voltage sense pins. The card sends a handshaking data stream to the logic controller, which then determines if this card requires VPP and if the card is designed for dual VCC. If the card is compatible with, and requires, a different VCC level, the logic controller commands the power controller to make this change by disabling VCC, waiting at least 100ms, and then reenabling the other VCC voltage. MIC2564A 10
PC Card Voltage Regulation The MIC2564A has been designed to meet or exceed PC Card voltage regulation specifications. The on-resistance of the FET switches will meet regulation requirements at 600mA and 1A respectively for VCC = 5V 3% and 3.3V 3%. Flash Memory Implementation When programming flash memory (standard +12V flash memories), the PC Card slot logic controller enables VPP on the MIC2564A, which connects VPP IN (nominally +12V) to VPP OUT. The low on-resistance of the MIC2564A switch allows using a small bypass capacitor on the VPP OUT pins, with the main filtering performed by a large filter capacitor on VPP IN. (Usually the main power supply filter capacitor is sufficient.) Using a small-value capacitor such as 0.1F on the output causes little or no timing delays. The VPP OUT transition from VCC to 12.0V typically takes 200s. After programming is completed, the logic controller signals to the MIC2564A, which then reduces VPP OUT to the VCC level. Break-before-make switching action and controlled rise times reduce switching transients and lower current spikes through the switch. Output Current and Protection The MIC2564A meets or exceeds all PCMCIA specifications. MIC2564A output switches are capable of passing the maximum current needed by any PC Card. For system and card protection, output currents are internally limited. For full system protection, long term (longer than a few milliseconds) output short circuits invoke overtemperature shutdown, protecting the MIC2564A, the system power supplies, the card socket pins, board traces, and the PC Card. Individual internal status registers for each slot indicate when power problems exist. Control Bus Interface Overview The MIC2564A power controller communicates with a logic controller (host adapter) via a 3-wire serial interface. A fourth control line attaches to the system reset line (RST#) and places all MIC2564A switches in the high impedance (off) state. The reset function is active low.
