The LTC(R)1314/LTC1315 provide the power switching necessary to control Personal Computer Memory Card International Association (PCMCIA) Release 2.0 card slots. When used in conjunction with a PC card interface controller, these devices form a complete minimum component count interface for palmtop, pen-based and notebook computers. The LTC1314/LTC1315 provide 0V, 3.3V, 5V, 12V and Hi-Z power output for flash VPP programming. A built-in charge pump produces 12V of gate drive for inexpensive N-channel 3.3V/5V VCC switching. The 12V regulator can be shut down when 12V is not required at VPPOUT. All digital inputs are TTL compatible and interface directly with industry standard PC card interface controllers. The LTC1314 is available in 14-pin SO and the LTC1315 in 24-pin SSOP.

APPLICATIONS INFORMATION
PCMCIA VPP control is easily accomplished using the LTC1314 or LTC1315 switching matrix. Two control bits (LTC1314) or four control bits (LTC1315) determine the output voltage and standby/operate mode conditions. Output voltages of 0V, VCCIN (3.3V or 5V), VPPIN, or a high impedance state are available. When either the high impedance or low voltage (0V) conditions are selected, the device switches into "sleep" mode and draws 0.1A of current from the VDD supply. The LTC1314/LTC1315 are low resistance power MOSFET switching matrices that operate from the computer system main power supply. Device power is obtained from VDD, which is 5V 0.5V. The gate drives for the NFETs (both internal and external) are derived from internal charge pumps, therefore VPPIN is only required when it's switched to VPPOUT. Internal break-before-make switches determine the output voltage and device mode. Flash Memory Card VPP Power Considerations PCMCIA compatible flash memory cards require tight regulation of the 12V VPP programming supply to ensure that the internal flash memory circuits are never subjected to damaging conditions. Flash memory circuits are typically rated with an absolute maximum of 13.5V and VPP must be maintained at 12V 5% under all possible load conditions during erase and program cycles. Undervoltage can decrease specified flash memory reliability and overvoltage can damage the device. VCC Switch Driver and VPP Switch Matrix Figures 1 and 2 show the approach that is very space and power efficient. The LTC1314/LTC1315 used in conjunction with the LT1301 DC/DC converter, provide complete power management for a PCMCIA card slot. The LTC1314/ LTC1315 and LT1301 combination provides a highly efficient, minimal parts count solution. These circuits are especially good for applications that are adding a PCMCIA socket to existing systems that currently have only 5V or 3.3V available. The LTC1314 drives three N-channel (LTC1315 six N-channel) MOSFETs that provide VCC pin power switching. On-chip charge pumps provide the necessary voltage to fully enhance the switches. With the charge pumps onchip, the MOSFET drive is available without the need for a 12V supply. The LTC1314/LTC1315 provide a natural break-before-make action and smooth transitions due to

APPLICATIONS INFORMATION
the asymmetrical turn-on and turn-off of the MOSFETs. The LT1301 switching regulator is in shutdown mode and consumes only 10A until the VPP pins require 12V. The VPP switching is accomplished by a combination of the LTC1314/LTC1315 and LT1301. The LT1301 is in shutdown mode to conserve power until the VPP pins require 12V. When the VPP pins require 12V, the LT1301 is activated and the LTC1314/LTC1315's internal switches route the VPPIN pin to the VPPOUT pin. The LT1301 is capable of delivering 12V at 120mA maintaining high efficiency. The LTC1314/LTC1315's break-before-make and slope-controlled switching will ensure that the output voltage transition will be smooth, of moderate slope, and without overshoot. This is critical for flash memory products to prevent damaging parts from overshoot and ringing exceeding the 13.5V device limit. With Higher Voltage Supplies Available Often systems have an available supply voltage greater than 12V. The LTC1314/LTC1315 can be used in conjunction with an LT1121 linear regulator to supply the PC card socket with all necessary voltages. Figures 3 and 4 show these circuits. The LTC1314/LTC1315 enable the LT1121 linear regulator only when 12V is required at the VPP pins. In all other modes the LT1121 is in shutdown mode and consumes only 16A. The LT1121 also provides thermal shutdown and current limiting features to protect the socket, the card and the system regulator. Supply Bypassing For best results, bypass VCCIN and VPPIN at their inputs with 1F capacitors. VPPOUT should have a 0.01F to 0.1F capacitor for noise reduction and electrostatic discharge (ESD) damage prevention. Larger values of output capacitor will create large current spikes during transitions, requiring larger bypass capacitors on the VCCIN and VPPIN pins.
