GENERAL DESCRIPTION
The OZ2206 is a dual slot PCMCIA (Personal Computer
Memory Card International Association) PC Card and
CardBus power controller. It is used in conjunction with a
serial data output, CardBus controller to control and
distribute Vcc and Vpp voltages to two PC Card slots.
When connected to 3.3V, 5V, and 12V system power
supplies, the OZ2206 can switch its Vcc and Vpp outputs
between 0V, 3.3V, and 5.0V, in accordance with the control
commands from the three-wire serial interface. The
OZ2206 also features low on-resistance MOSFET switches
for 5V and 3.3V Vcc.
The OZ2206 operation does not require 12V and 5V
supplies, making it possible to operate the PC cards in low-
power 3.3V modes. The internal logic and the MOSFET
drive circuitry are powered by the 3V supply input.
The OZ2206 is protected by over temperature shutdown,
and it protects itself and the system with current limiting
and cross-conduction lockout.
The OZ2206 is designed for full compatibility with the
PCMCIA PC Card Specification, including the CardBus and
Zoomed Video (ZV) options, and is pin-to-pin compatible
with Texas Instrument’s TPS2206/2216.
