Dual-Slot PCMCIA Analog Power Controllers
_______________General Description
The MAX613/MAX614 contain switches for the VPP supply-voltage lines for Personal Computer Memory Card International Association (PCMCIA) Release 2.0 card slots. These ICs also contain level-translator outputs to switch the PCMCIA card VCC. The MAX613 allows digital control of two separate VPP lines that can be switched between 0V, VCC, +12V, and high impedance. It also includes level shifters that allow the control of N-channel power MOSFETs for connecting and disconnecting the slot VCC supply voltage. The MAX614 controls a single VPP supply-voltage line and includes one level shifter in an 8-pin package.

_______________Detailed Description
VPP Switching
The MAX613/MAX614 allow simple switching of PCMCIA card VPP to 0V, +5V, and +12V. On-chip power MOSFETs connect AVPP and BVPP to either GND, VCCIN, or VPPIN. The AVPP0 and AVPP1 control logic inputs determine AVPP's state. Likewise, BVPP0 and BVPP1 control BVPP. AVPP and BVPP can also be programmed to be high impedance. Each PCMCIA card slot has two VPP voltage inputs labeled VPP1 and VPP2. Typically, VPP1 supplies the flash chips that store the low-order byte of the 16-bit words, and VPP2 supplies the chips that contain the high-order byte. Programming the high-order bytes separately from the low-order bytes may be necessary to minimize +12V current consumption. A single 8-bit flash chip typically requires at most 30mA of +12V VPP current during erase or programming.
Thus, systems with less than 60mA current capability from +12V cannot program two 8-bit flash chips simultaneously, and need separate controls for VPP1 and VPP2. Figure 1 shows an example of a power-control circuit using the MAX613 to control VPP1 and VPP2 separately. Figure 1's circuit uses a MAX662 charge-pump DC-DC converter to convert +5V to +12V at 30mA output current capability without an inductor. When higher VPP current is required, the MAX734 can supply 120mA. Use the MAX614 for single-slot applications that do not require a separate VPP1 and VPP2. Figure 2 shows the MAX614 interfaced to the Vadem VG-465 single-slot controller. To prevent VPP overshoot resulting from parasitic inductance in the +12V supply, the VPPIN bypass capacitor's value must be at least 10 times greater than the capacitance from AVPP or BVPP to GND; the AVPP and BVPP bypass capacitors must be at least 0.01F.

VCC Switching
The MAX613/MAX614 contain level shifters that simplify driving external power MOSFETs to switch PCMCIA card VCC. While a PCMCIA card is being inserted into the socket, the VCC pins on the card edge connector should be powered down to 0V to prevent "hot insertion" that may damage the PCMCIA card. The MAX613/MAX614 MOSFET drivers are open drain. Their rise time is controlled by an external pull-up resistor, allowing slow turnon of VCC power to the PCMCIA card. The DRV3 and DRV5 pins on the MAX613 and the DRV pin on the MAX614 are open-drain outputs pulled down with internal N-channel devices. The gate drive to these internal N-channel devices is powered from VCCIN, regardless of VPPIN's voltage. If VCCIN is left unconnected or less than 2V is applied to VCCIN, the DRV3/DRV5/DRV gate drivers will not sink current. To switch VCC (M1 and M2 in Figure 1), use external N-channel power MOSFETs. M1 and M2 should be logic-level N-channel power MOSFETs with low on resistance. The Motorola MTP3055EL and Siliconix Si9956DY MOSFETs are both good choices. Turn on M1 and M2 by pulling their gates above +5V. With the gates pulled up to VPPIN as shown in Figure 1, VPPIN should be at least 10V so that with VCC = 5.5V, M1 and M2 have at least 4.5V of gate drive.

LOGIC INPUT VCC1 0 0 1 1 VCC0 0 1 0 1 DRV3 0V HI-Z 0V 0V OUTPUT DRV5 0V 0V HI-Z 0V
The gates of M1 and M2 can be pulled up to any 10V to 20V source, and do not need to be pulled up to VPPIN. Typically, the +12V used for VPPIN is supplied from a +5V to +12V switching regulator. To save power, the +5V to +12V switching regulator can be shut down when not using the VPP programming voltage, allowing VPPIN to fall below +5V. In this case, M1 and M2 should not be pulled up to VPPIN, since M1 and M2 cannot be turned on reliably when VPPIN falls below +10V. Any clock source can be used to generate a high-side gate-drive voltage by using capacitors and diodes to build an inexpensive charge pump. Figure 3 shows a charge-pump circuit that generates 10V from a +5V logic clock source.

__________Applications Information
The MAX613 contains all the gate drivers and switching circuitry needed to support a +3.3V/+5V VCC PCMCIA slot with minimal external components. Figure 4 shows the analog power control necessary to support two dual voltage PCMCIA slots. The A:VCC and B:VCC pins on the Intel 82365SL DF power the drivers for the control signals that directly connect to the PCMCIA card. A 3.3V card needs 3.3V logic-level control signals and the capability to program VPP1 and VPP2 to 3.3V. The MAX613's VCCIN is switched with slot VCC, so AVPP0 = 1 and AVPP1 = 0 causes AVPP = slot VCC. Likewise, A:VCC and B:VCC are connected to VCCIN, so the Intel 82365SL DF control signals to the PCMCIA card are the right logic levels. PCMCIA card interface controllers other than the Intel 82365SL DF can be used with Figure 4's circuit. Table 4 shows the pins on the Cirrus Logic CL-PD6720 that perform the same function as the Intel 82365SL DF pins.
