TPS2216ADB

Power Distribution Switches, Load Drivers Overview

The TPS2216ADB is a dual-slot PC Card power switch designed for serial PCMCIA controllers. It integrates two independent high-side switches to manage power distribution for PC Card and CardBus slots. The device features a serial interface for control, allowing configuration of output states and monitoring of fault conditions. It supports standard PC Card voltage levels including 3.3V, 5V, and 12V supplies. The component includes built-in protection mechanisms such as current limiting and thermal shutdown to safeguard connected peripherals and the host system during abnormal operating conditions.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix (e.g., ADB vs ADBG4) against the manufacturer's latest datasheet to confirm package type and environmental compliance status. Ensure the serial interface timing requirements match the host controller specifications. Confirm availability as older revisions may be discontinued or replaced by updated variants within the same family.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing systems requiring dedicated power control for dual PC Card slots via a serial interface. It is suitable for applications needing precise voltage sequencing and fault monitoring for removable storage media. Consider the SSOP package constraints for PCB layout and ensure adequate thermal dissipation for the intended operating environment.

Power Distribution Switches, Load Drivers Part Context

This part belongs to Texas Instruments' TPS2216 series of power switches specifically engineered for PC Card and CardBus applications.
