TPS2205IDB

Power Distribution Switches, Load Drivers Overview

The TPS2205IDB is a dual-slot PC card power-interface switch designed for parallel PCMCIA controllers. It integrates four high-side switches within a single package, utilizing a 3:4 input-to-output ratio to manage power distribution efficiently. The device supports load voltages of 3.3V, 5V, and 12V, with a maximum continuous output current of 1A per channel. Key electrical characteristics include a typical on-resistance of 103 milliohms and a maximum of 110 milliohms. It operates reliably across an extended temperature range from -40°C to +85°C and is housed in a 32-PowerTSSOP surface-mount package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required operating temperature range and voltage ratings for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing systems that require simultaneous control of multiple PCMCIA slots using a parallel interface architecture. Consider the 3:4 control ratio and the requirement for external pull-up or drive circuitry if necessary. Evaluate the thermal performance requirements given the on-resistance values to ensure adequate heat dissipation within the 32-PowerTSSOP footprint.

Power Distribution Switches, Load Drivers Part Context

The TPS2205 belongs to the TPS22xx series of power switches from Texas Instruments, specifically optimized for PCMCIA applications. Unlike general-purpose load switches, this family addresses the specific timing and power sequencing needs of PC Card standards. The IDB designation indicates a specific package configuration within this product line, distinct from the IDAP or IDAPR variants which may differ in packaging or reel specifications.

Power Distribution Switches, Load Drivers Replacement Considerations

Official substitutes include TPS2205IDAPG4 and TPS2205IDAPRG4. Verify pin compatibility and package dimensions before substitution.
