Single-Channel CardBus and PCMCIA VCC/VPP
Power-Switching Network
The MAX1602 DC power-switching IC contains a network of low-resistance MOSFET switches that deliver
selectable VCC and VPP voltages to a single CardBus
or PC Card host socket. Key features include lowresistance switches, small packaging, soft-switching
action, and compliance with PCMCIA specifications for
3V/5V switching. 3.3V-only power switching for fast,
32-bit CardBus applications is supported in two ways:
low-resistance 3.3V switches allow high 3.3V load currents (up to 1A); and completely independent internal
charge pumps let the 3.3V switch operate normally,
even if the +5V and +12V supplies are disconnected or
turned off to conserve power. The internal charge
pumps are regulating types that draw reduced input
current when the VCC switches are static. Power consumption is automatically reduced to 11µA max when
the outputs are high-Z or GND.
Other key features include guaranteed specifications
for output current limit level, and guaranteed specifications for output rise/fall times (in compliance with
PCMCIA specifications). Reliability is enhanced by
thermal-overload protection, accurate current limiting,
an overcurrent-fault flag output, and undervoltage lockouts. The CMOS/TTL-logic interface is flexible, and can
tolerate logic input levels in excess of the positive supply rail.
The MAX1602 fits a complete CardBus/PCMCIA switch
into a space-saving, 16-pin QSOP package.

Note 1: There are no parasitic diodes between any of these pins, so there are no power-up sequencing restrictions (for example,
logic input signals can be applied even if all of the supply voltage inputs are grounded).
Note 2: VCC and VPP outputs are internally current limited. See the Electrical Characteristics.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Single-Channel CardBus and PCMCIA VCC/VPP
Power-Switching Network
_______________Detailed Description
The MAX1602 power-switching IC contains a network of
low-resistance MOSFET switches that deliver selectable
VCC and VPP voltages to two CardBus or PC Card host
socket. Figure 1 is the detailed block diagram.
The power-input pins (VY, VX, 12IN) are completely
independent, however, power must always be applied
to VY for proper operation. Low inrush current is guaranteed by controlled switch rise times. VCC’s 100µs minimum output rise time is 100% tested with a 1µF
capacitive load, and VPP’s 1ms minimum rise time is
guaranteed with a 0.1µF load. These respective capacitive loads are chosen as worst-case card-insertion parameters. The internal switching control allows VCC and
VPP rise times to be controlled, and makes them nearly

independent of resistive and capacitive loads (see risetime photos in the Typical Operating Characteristics).
Fall times are a function of loading, and are compensated by internal circuitry.
Power savings is automatic: internal charge pumps draw
very low current when the VCC switches are static.
Standby mode reduces switch supply current to 11µA.
Operating Modes
The MAX1602 is compatible with the Cirrus
CL-PD67XX, Databook DB86184, and Intel 82365SL PC
Card Interface Controllers (PCIC). Four control inputs
select the internal switches’ positions and the operating
modes according to the input code. Select the proper
code format for the chosen controller with the CODE
input pin (see Pin Description and Tables 1, 2, and 3).
CODE reconfigures the logic decoder to one of three
interface controllers:
Low = Standard “Intel” code (Figure 3)
High = “Cirrus” code (Figure 2)
Mid-supply = “Databook” code (Figure 4)
An additional 1µA (3µA max) of VY supply current will
flow if CODE = mid-supply (VY/2).
The MAX1602 has two operating modes: normal and
standby. Normal mode supplies the selected outputs
with their appropriate supply voltages. Standby mode
places all switches at ground, high impedance, or a
combination of the two.

Overcurrent Protection
Peak detecting circuitry protects both the VCC and VPP
switches against overcurrent conditions. When current
through any switch exceeds the internal current limit
(4A for VCC switches and 200mA for VPP switches) the
switch turns off briefly, then turns on again at the controlled rise rate. If the overcurrent condition lasts more
than 2µs, the FAULT output goes low. FAULT is not
latched. A continuous short-circuit condition results in a
pulsed output current and a pulsed FAULT output until
thermal shutdown is reached. FAULT is open-drain and
requires an external pull-up resistor.
Thermal Shutdown
If the IC junction temperature rises above +150°C, the
thermal shutdown circuitry opens all switches, including
the GND switches, and FAULT is pulled low. When the
temperature falls below +130°C, the switches turn on
again at the controlled rise rate. If the overcurrent condition remains, the part cycles between thermal shutdown and overcurrent.
Undervoltage Lockout
If the VX switch input voltage drops below 1.9V, the
associated switch turns off and FAULT goes low. For
example, if VY is 3.3V and VX is 0V, and if the interface
controller selects VY, the VCC output will be 3.3V. If VX
is selected, VCC changes to a high-impedance output
and FAULT goes low.
When a voltage is initially applied to 12IN, it must be
greater than 8V to allow the switch to operate.
Operation continues until the voltage falls below 2V
(the VPP output is high impedance).
When VY drops to less than 2.6V, all switches are
turned off and the VCC and VPP outputs are high
impedance.
__________Applications Information
Supply Bypassing
Bypass the VY, VX, and 12IN inputs with ceramic 0.1µF
capacitors. Bypass the VCC and VPP outputs with a
0.1µF capacitor for noise reduction and ESD protection.
