General Description
The MIC2561 V
Computer Memory Card International Association) memory
card power supply pins, both V
switches voltages from the system power supply to V
V
(OFF, 3.3V and 5.0V) and the V
5V, or 12.0V) required by PCMCIA cards. Output voltage is
selected by two digital inputs for each output and output
current ranges up to 750mA for V
higher V
mance MIC2560.
The MIC2561 provides power management capability under
the control of the PC Card controller and features overcurrent
and thermal protection of the power outputs, zero current
“sleep” mode, suspend mode, low power dynamic mode, and
ON/OFF control of the PCMCIA socket power.
The MIC2561 is designed for efficient operation. In standby
(“sleep”) mode the device draws very little quiescent current,
typically 0.01µA. The device and PCMCIA port is protected by
current limiting and overtemperature shutdown. Full cross-
conduction lockout protects the system power supply.
