TPS2201IDB

Power Distribution Switches, Load Drivers Overview

The TPS2201IDB is a single-channel load switch manufactured by Texas Instruments, designed for PCMCIA and CardBus applications. It features an ultra-low on-resistance of 50 milliohms typical at room temperature, enabling efficient power delivery with minimal voltage drop. The device supports input voltages ranging from 1.65 volts to 5.5 volts and delivers a continuous output current of up to one ampere. Integrated protection mechanisms include fixed current limiting and thermal shutdown to safeguard connected loads during fault conditions. Packaged in a compact SOT-23 footprint, it offers high reliability for portable electronics requiring precise power management.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific package variant when ordering, as the TPS2201 family includes different suffixes such as IDBR or IDBT indicating distinct reel quantities or tape-and-reel specifications. Confirm that the selected part number matches the required lead time and availability status directly from the manufacturer's official channel. Ensure the procurement documentation explicitly states the operating temperature range and compliance with relevant environmental standards before finalizing the purchase order.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing circuits requiring a compact, low-profile solution for managing power to peripheral devices like PCMCIA cards. The choice is driven by the need for low insertion loss combined with robust fault protection in space-constrained environments. Evaluate the input voltage range to ensure it aligns with the system's supply rails and verify that the one-ampere current rating sufficiently covers the peak load requirements of the target application without triggering premature shutdown.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS22xx series of load switches from Texas Instruments, which are optimized for portable applications. The series provides integrated protection features typically found in discrete solutions but within a small footprint. The TPS2201 specifically targets legacy and modern interfaces requiring reliable power sequencing and protection for memory and I/O cards, serving as a critical interface between the main system power rail and peripheral slots.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes may include other single-channel load switches from Texas Instruments with similar current ratings and package types. Verify pin-to-pin compatibility and electrical parameter equivalence, particularly regarding on-resistance and current limit thresholds, before implementing any cross-brand replacement. Ensure the alternative device meets the same thermal and voltage specifications for the intended application.
