MAX780
_______________General Description
The MAX780A provides the power switching and status
signals necessary to control two Personal Computer
Memory Card International Association (PCMCIA)
Release 2.0 card slots. The MAX780A, used in conjunction with a PC Card Interface Digital Controller, forms a
complete, minimum component count PCMCIA interface
for palmtop and notebook computers.
The MAX780A incorporates two 0V/+5V/+12V/highimpedance power outputs for flash VPP programming,
level shifters for power MOSFET control of two separate +3.3V/+5V supplies, and two V PP power-ready
status signals. The MAX780A may be directly connected to the control outputs from a PCMCIA digital
controller, or may be configured to use internal edgetriggered registers for connection to the CPU data bus.
The MAX780B has all the features of the MAX780A but
omits the reference and V PP valid indicators. The
MAX780C has all the features of the MAX780A but
omits the registers for the digital inputs. The MAX780D
omits the reference, the VPP valid indicators, and the
digital input registers.

NAME
FUNCTION
C2
Pin-strap input that selects edge-triggered register or direct digital inputs. Tying C2 to
VCCIN makes the logic inputs edge triggered; inputs to pins 4-11 are clocked in on the
rising edge of WR. Tying C2 to GND allows control signals to be directly applied to the
logic inputs on pins 4-11. Connect to GND for MAX780C.
C1
Pin-strap input that selects one of two logic decode modes for the digital inputs. See Tables 1-3.
WR
Write pulse input. When C2 is tied to VCCIN, a rising edge on WR clocks in the VCC
and VPP enables. When C2 is tied to GND, inputs to WR have no effect. Connect to
GND for MAX780C.

VPP Switching
All four versions (A, B, C, and D) of the MAX780 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 the state of
AVPP. Likewise, BVPP0 and BVPP1 control BVPP.
To prevent VPP overshoot due to parasitic inductance
in the +12V supply, the VPPIN bypass capacitor (CIN)
should be 10 times greater than the capacitance from
AVPP (CA) or BVPP (CB) to GND. Hence, when CA
and CB are 0.1µF, CIN should be 1.0µF.
The AGPI and BGPI status outputs signal when the VPP
lines are valid. AGPI goes low when AVPP exceeds
11.05V; BGPI goes low when BVPP exceeds 11.05V.
The status outputs and the reference are only active
when SHDN is high.
Pulling SHDN low puts the MAX780 into a low supplycurrent mode and disables the reference and the AGPI
and BGPI status outputs. The V CC level shifters
ADRV5, ADRV3, BDRV5, BDRV3 are all forced low
when SHDN is low. VPP switching is not affected by the
state of SHDN. Program AVPP and BVPP to 0V for lowest power consumption when SHDN is low. Wait at
least 200µs after bringing the MAX780 out of shutdown
before checking AGPI or BGPI since the reference
needs time to stabilize.
VCC Switching
The MAX780 contains level shifters that simplify driving
external power MOSFETs to switch PCMCIA card VCC
to 3.3V and 5V. While a PCMCIA card is being inserted into the socket, the VCC pins on the card edge connector should be powered down to 0V so that “hot
insertion” does not damage the PCMCIA card. The
simplest way to accomplish this is to pull out a
mechanical switch before the PCMCIA card is inserted.
The mechanical switch can be pushed in only when
the card has been fitted snugly into its socket. The
MAX780 Detailed Operating Circuit shows this method.
In the Detailed Operating Circuit, (with the mechanical
interlock switch closed) the PCMCIA card VCC cannot
be pulled more than a diode drop below 3.3V. The Nchannel power MOSFET that connects VCC to 3.3V has
its drain tied to VCC and its source tied to 3.3V, so that
its body diode prevents the card’s VCC from falling to
0V. If it were rotated so that the source connected to
VCC, then applying 5V to VCC would short the 5V supply to the 3.3V supply via the MOSFET’s body diode.
_______________________________________________________________________________________
Dual-Slot PCMCIA Analog Power Controller
Switching Speed
The drive to the external MOSFETs ensures that the
3.3V supply is never connected to the 5V supply. This
is done by turning these transistors off quickly (using
active pull-down circuitry), and on more slowly (using
external pull-up resistors). The turn-on delay depends
on the value of the pull-up resistors, and on the gate
capacitance of the switching transistors. To save
power, use high-value resistors of up to 10MΩ.
However, note that high-value resistors will increase the
time it takes to turn on the switched supplies
In these circumstances, a separate gate-drive supply is
needed to turn on the external FETs. Ideally it should
have a low quiescent current and be capable of being
turned off when read access to the PCMCIA port is not
required. Doubling or tripling charge pumps can easily
be built using a convenient clock signal from elsewhere
in the system. Buffering the clock signal with a suitable
gate provides on/off control, as shown in Figure 5.
When driven at 100kHz or more by a CMOS gate powered from 5V, the doubler circuit outputs 8.6V when
loaded with 25kΩ (equivalent to four 100kΩ pull-up
resistors). Under similar conditions, but when running
from 3.3V, the tripler circuit produces 7.9V.
+5V
__________Applications Information
The MAX780 can be used with PCMCIA controllers
other than the Intel 82365SL DF. Figure 2 shows the
logic connections to the Cirrus Logic CL-PD6720
PCMCIA Host Adapter.
The MAX780 does not need a PCMCIA controller to
function. Tie C2 to VCCIN to allow direct VCC and VPP
control from the system bus. Figure 3 shows the connection to the system bus. Figure 4 shows the timing
requirements.
Reading from a PCMCIA Port
without Using the VPP Supply
In the Typical Operating Circuit, VCC is switched to
the PCMCIA ports using the 12V VPP supply, which
provides the gate drive needed to turn on the external
N-channel MOSFETs. In some cases, the high-power
VPP supply is only available when information has to be
written to the PCMCIA port, not when data is being
read. The VPP supply may have a quiescent current of
several milliamps, so it consumes more power than is
necessary simply to provide gate drive for some FETs.

If a mechanical interlock switch cannot be used, an
extra MOSFET must be added, as shown in Figure 1.
Placing two N-channel MOSFETs in series with their
body diodes facing in opposite directions allows VCC to
be shut down to 0V without using a mechanical switch.
