RICOH R5533V User Guide

Summary

The R5533V is a robust PCMCIA power controller engineered for switching voltages efficiently among 0V, 3.3V, or 5.0V in card-bus slots. Featuring low ON resistance MOSFET technology, built-in overcurrent protection, and thermal shutdown safeguards, it is ideal for developing reliable power supply switches, readers, and writers. This manual provides comprehensive technical documentation, including the SSOP-16 pin configuration, absolute maximum ratings, electrical characteristics, and detailed operating parameters necessary for hardware design engineers.

PCMCIA Power Controller

NO.EA-176-100709

OUTLINE The R5533V Series switch the VCC voltage among 0V, 3.3V or 5.0V. And the VPP voltage is outputted in between either OFF, 0V, 3.3V or 5.0V conditions. When the VCC or VPP pin are short-circuited to the GND, the minimum current limit protection values are VCC pin=1A and VPP pin=0.2A. R5533V is suitable for standard type of PCMCIA power controllers.

FEATURES • Low ON resistance Nch MOSFET switch • Built-in Over Current Limit Protection Function • Built-in Thermal Shutdown Protection • Open Drain Flag Pin • Break-Before-Make Switching • Package: SSOP-16 pin

APPLICATIONS • Power Supply Switch for PC Card • Power Supply Control for a card-bus slot • PC Card Reader / Writer
