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 out-
puts 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 con-
necting 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.

FUNCTION
_______________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 simulta-
neously, 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 cur-
rent 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 0.01µF.
