Product details
Overview
TPS2202IDBLE from Texas Instruments is a dual-slot PC Card (PCMCIA) power-interface switch IC that integrates VCC and Vpp switching for 3.3-V, 5-V, and 12-V card power distribution in notebook computers and PDAs. It features break-before-make switching, 160-mΩ rDS(on) for 5-V VCC outputs, internal charge pump (no external capacitors), and thermal/short-circuit protection. Its 30-pin SSOP (DB) package supports serial interface control with only three I/O leads.
For engineers reviewing the TPS2202IDBLE datasheet, TPS2202IDBLE pinout, TPS2202IDBLE application, or TPS2202IDBLE equivalent, key selection criteria include its dual-slot 1-A VCC/150-mA Vpp current capability, 83-µA typical quiescent current, 12-V Vpp programmability without continuous 12-V supply, and compliance with PCMCIA 3.3-V/5-V voltage-transitioning requirements.
Technical Context
The TPS2202IDBLE implements two independent power-switch channels-AVCC/AVPP and BVCC/BVPP-each supporting selectable 3.3-V, 5-V, or 12-V output via internal MOSFETs fabricated in LinBiCMOS process. It uses a 3-wire serial interface (DATA, CLOCK, LATCH) to configure slot power states, eliminating need for dedicated GPIOs from the PCMCIA controller.
Its internal charge pump generates gate-drive voltage from 5-V VDD, enabling full shutdown of external 12-V supply except during flash programming. Overcurrent detection triggers OC pin assertion and linear current limiting; thermal shutdown disables all outputs if junction temperature exceeds 150°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-slot PCMCIA power-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2202IDBR | Same die, DB package tape-and-reel variant - identical electrical specs and pinout | No functional difference; intended for automated SMT production vs. sample/bench use | Select TPS2202IDBR for volume manufacturing; TPS2202IDBLE is same device in cut-tape format |
| TPS2202Y | Chip-scale version without package - requires custom assembly; TJmax = 150°C same, but no defined thermal pad | Suitable only for hybrid modules or embedded substrates where DB package is mechanically incompatible | Choose TPS2202Y only when board space constraints prohibit SSOP; requires bond-wire or flip-chip integration |
Compared with TPS2202IDBLE, the TPS2202IDBR offers identical performance in tape-and-reel packaging for pick-and-place lines, while the TPS2202Y provides bare-die flexibility at the cost of assembly complexity and lack of standardized thermal path - neither is pin-compatible replacement for legacy DB-footprint designs requiring cut-tape delivery.

FAQ
What is the maximum continuous current supported by each VCC output of the TPS2202IDBLE?
The TPS2202IDBLE supports up to 1 A continuous current per VCC output (AVCC and BVCC) at 25°C ambient, with internal current limiting engaging above 0.75 A at 85°C junction temperature. This rating meets PCMCIA specification requirements for disk drive spin-up loads and ensures reliable operation without external fusing. The TPS2202IDBLE maintains this capability across its full –40°C to +85°C operating range.
Does the TPS2202IDBLE require an external 12-V supply to operate its internal charge pump?
No - the TPS2202IDBLE uses an internal charge pump powered solely from the 5-V VDD supply to generate gate-drive voltages, so the external 12-V input is needed only during flash memory programming or erase operations. This architecture allows the 12-V rail to be disabled during normal operation, significantly reducing system power consumption. The TPS2202IDBLE achieves this without external capacitors or additional components.
How does the TPS2202IDBLE meet PCMCIA 3.3-V/5-V voltage-transitioning requirements?
The TPS2202IDBLE implements programmable active discharge of VCC outputs to ground, ensuring residual card capacitance drops below 0.8 V within 100 ms - satisfying the PCMCIA requirement for safe 5-V-to-3.3-V transitions. Its break-before-make switching prevents cross-conduction, and the serial interface allows precise sequencing of voltage application and discharge per slot. This functionality is built into the TPS2202IDBLE's hardware state machine and requires no host firmware intervention.
What is the purpose of the OC (Overcurrent) pin on the TPS2202IDBLE?
The OC pin on the TPS2202IDBLE is an open-drain logic-level output that goes low during overcurrent conditions (e.g., shorted card or excessive load), providing immediate fault signaling to the host microcontroller. Unlike simple shutdown, OC asserts before thermal shutdown occurs, enabling firmware to log the event, identify the faulty slot, and initiate diagnostics or user alerts. The TPS2202IDBLE continues to monitor and report until the fault clears or thermal limit is reached.
Is the TPS2202IDBLE compatible with modern USB-C or ExpressCard interfaces?
No - the TPS2202IDBLE is designed exclusively for legacy PCMCIA/PC Card (Type I/II) interfaces and does not support USB-C, ExpressCard, or PCIe-based expansion standards. Its pinout, control protocol, voltage ranges, and timing parameters align strictly with the PCMCIA 3.3-V/5-V specification. For newer interfaces, Texas Instruments offers separate solutions such as TPS6598x series for USB-C PD or TPS65912 for multi-rail PMICs - the TPS2202IDBLE remains a purpose-built component for maintaining legacy PCMCIA compatibility.
