What are the key features of TPS2211IDBRAN?
- Single-slot PC Card power switch supporting 1 A continuous current on VCC rails for PCMCIA and CardBus slot management
- Parallel interface enables direct connection to host controller logic without serial command overhead, simplifying firmware integration
- Integrated power sequencing and protection manage VCC and VPP rails independently to meet PC Card specification requirements
- Small-outline package minimises board space on laptop and embedded PC Card host controller designs
What is TPS2211IDBRAN used for?
The TPS2211IDBRAN is designed for single-slot PCMCIA and CardBus host controller circuits in laptops, embedded computers, and industrial PCs where 1 A switched power delivery to PC Card slots is required. Its parallel interface simplifies logic connectivity to host bridge chips, reducing software overhead for slot power management. The device handles both VCC and VPP rails with integrated protection, meeting the full PC Card electrical specification for 3.3 V and 5 V card types.

Frequently Asked Questions
What current capacity does TPS2211IDBRAN switch on the PC Card VCC rail, and which card standards does it support?
The TPS2211IDBRAN switches up to 1 A continuous current on the VCC power rail, meeting the current requirements of both 3.3 V and 5 V PCMCIA Type I, Type II, and CardBus PC Cards. The device manages VCC and VPP rails independently with integrated fault protection, enabling compliant single-slot host controller designs without external discrete power switches or sequencing logic.
How does the parallel interface of TPS2211IDBRAN compare with a serial-commanded power switch for PC Card host integration?
The parallel interface maps control signals directly to logic pins, allowing the host PC Card bridge to assert slot power states in a single clock cycle without serialising command bytes or implementing a communication protocol. This reduces host firmware complexity and latency compared with SPI or I2C controlled switches, making the TPS2211IDBRAN straightforward to integrate alongside legacy 16-bit PCMCIA and 32-bit CardBus host controllers at 3.3 V logic levels.
What package does TPS2211IDBRAN use, and how does that affect PCB layout near a CardBus connector?
The TPS2211IDBRAN is housed in a small-outline package, with the DBRA variant using a 16-pin SSOP (TSSOP-equivalent) outline with 0.65 mm pitch that occupies minimal board area between the host bridge and the CardBus connector. Designers should route VCC and VPP current paths with appropriately wide copper pours to handle the 1 A load current while keeping bypass capacitors of at least 10 µF within 5 mm of the output pins to suppress transients during card insertion.
For a new embedded PC design, when should an engineer consider TPS2211IDBRAN over a general-purpose load switch?
TPS2211IDBRAN should be chosen when the design requires PC Card specification-compliant VCC and VPP dual-rail sequencing with a parallel control bus, which generic load switches do not implement. A general-purpose 1 A switch lacks built-in knowledge of the PC Card insertion sequence and VPP voltage programming, requiring additional logic and potentially violating the PC Card specification timing requirements of under 300 ms power ramp-up.
