Product details
Overview
TPS2202IDFR 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 and PDA host systems. 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. Used in serial PCMCIA controller interfaces to replace discrete MOSFETs and fuses.
For engineers reviewing the TPS2202IDFR datasheet, TPS2202IDFR pinout, TPS2202IDFR application, or TPS2202IDFR equivalent, this device delivers integrated dual-slot power control with serial interface reduction, programmable Vpp/VCC sequencing, and real-time overcurrent reporting via OC pin - critical for battery-powered portable designs requiring PCMCIA compliance and fault isolation.
Technical Context
The TPS2202IDFR implements a LinBiCMOS-based dual-channel power switch architecture with independent control of AVCC/AVPP and BVCC/BVPP outputs. Each channel supports selectable voltage delivery (0 V, 3.3 V, 5 V, or 12 V) and includes dedicated power-good status (APWR_GOOD/BPWR_GOOD) and overcurrent flag (OC).
Its 3-wire serial interface (DATA, CLOCK, LATCH) replaces up to 14 parallel control lines, enabling compact host controller integration. The internal charge pump generates gate-drive voltage from 5-V VDD, allowing 12-V supply to be disabled except during flash programming - reducing system standby current to 1 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Supply | 4.75–5.25 V - powers internal logic and charge pump; enables 12-V Vpp switching without external high-voltage rail |
| rDS(on) (5-V VCC) | 160 mΩ typ - limits voltage drop to ≤160 mV at 1 A, meeting PCMCIA 5-V ±5% tolerance |
| rDS(on) (12-V Vpp) | 1 Ω max - supports 150 mA flash programming current with <150 mV drop |
| Quiescent Current | 1 µA in shutdown - extends battery life during card slot idle states |
| Output Current Limit | 1 A for VCC, 200 mA for Vpp - internally limits fault current without fuses or external sense resistors |
| Switching Speed | 5 ms rise time for Vpp, 1.2 ms for VCC - ensures controlled power ramp per PCMCIA 3.3-V/5-V transition timing |
| ESD Rating | 2 kV HBM - protects against handling damage in manufacturing and field service environments |
Pinout & Package
TPS2202IDFR is housed in a 30-pin SSOP (DB package), 0.635 mm pitch, 7.2 mm × 5.3 mm body size. Pin 1 marked by dot; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3V (15,16,17) | Input | 3.3-V VCC supply input for card power - connects to host 3.3-V rail; three pins reduce impedance |
| 5V (1,2,30) | Input | 5-V VCC supply input - connects to host 5-V rail; triple-pin configuration supports ≥1 A total |
| 12V (7,24) | Input | 12-V Vpp supply input - powers flash memory programming; dual-pin layout minimizes IR drop |
| AVCC (9,10,11) | Output | Switched 3.3/5-V output for Slot A - drives card VCC with break-before-make sequencing |
| AVPP (8) | Output | Switched 3.3/5/12-V output for Slot A - enables flash erase/write when 12-V active |
| APWR_GOOD (13) | Output | Active-low power-ready signal - asserts low only when AVPP is within 10.72–11.4 V window |
| BVCC (20,21,22) | Output | Switched 3.3/5-V output for Slot B - independent control allows mixed-voltage card operation |
| BVPP (23) | Output | Switched 3.3/5/12-V output for Slot B - supports concurrent or staggered Vpp activation |
| BPWR_GOOD (19) | Output | Active-low power-ready for Slot B - decoupled from Slot A for independent fault detection |
| CLOCK (4) | Input | Serial interface clock - positive-edge triggered; supports up to 2.5 MHz for fast configuration |
| DATA (3) | Input | Serial data input - 9-bit command word (D0–D8) defines slot enable, voltage, and sequencing |
| LATCH (5) | Input | Command strobe - latches DATA on rising edge; must occur before next CLOCK edge |
| GND (12) | Ground | Common reference - single ground pin serves analog and digital sections |
| OC (18) | Output | Overcurrent flag - open-drain, active-low; signals fault condition to host microcontroller |
| VDD (25) | Input | 5-V chip supply - powers internal logic and charge pump; must be stable before configuration |
| NC (6,14,26–29) | No connect | No internal connection - must be left floating or tied to GND per PCB layout best practice |

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 in tape-and-reel (R suffix); identical electrical specs and pinout | No functional difference - optimized for automated SMT assembly vs. manual prototyping | Select TPS2202IDBR for volume production; TPS2202IDFR is same device in DF package with different reel packaging |
| TPS2201IDB | Single-slot variant; lacks BVCC/BVPP outputs and BPWR_GOOD; 24-pin DB package | Supports only one PC Card slot; cannot replace TPS2202IDFR in dual-slot designs without redesign | Choose only if system requires single-slot capability and board space is constrained - not a drop-in substitute |
Compared with TPS2202IDFR, the TPS2202IDBR offers identical performance in a tape-and-reel format for high-volume SMT, while the TPS2201IDB reduces cost and footprint for single-slot applications but requires PCB redesign and loses independent Slot B control and monitoring.

FAQ
What is the primary function of the TPS2202IDFR in a PCMCIA host system?
The TPS2202IDFR serves as a fully integrated dual-slot PC Card power-interface switch, managing VCC (3.3 V/5 V) and Vpp (3.3 V/5 V/12 V) delivery to two independent PCMCIA slots. It replaces discrete MOSFETs, fuses, and control logic while enforcing PCMCIA timing requirements including break-before-make switching, 100-ms VCC discharge, and 3.3-V/5-V transition sequencing. Its internal charge pump eliminates dependency on a continuously powered 12-V rail - a key enabler for battery life in portable designs using the TPS2202IDFR.
Does the TPS2202IDFR require external capacitors for its charge pump?
No, the TPS2202IDFR does not require external capacitors for its internal charge pump. As confirmed in the datasheet (SLVS103B, section "Fully Integrated VCC and Vpp Switching"), the charge pump is fully monolithic and self-contained within the IC. This eliminates the need for external flying or reservoir capacitors - simplifying layout, reducing bill-of-materials count, and improving reliability. The 12-V Vpp supply can therefore be gated externally and enabled only during flash programming, a feature directly enabled by the capacitor-free charge pump in the TPS2202IDFR.
How does the TPS2202IDFR handle overcurrent conditions on its outputs?
The TPS2202IDFR uses internal sense FETs - not fuses or external sense resistors - to monitor output current on each VCC and Vpp line. When overcurrent is detected, it linearly limits output current (e.g., 0.75–1.9 A for VCC, 120–400 mA for Vpp) to prevent damage. Simultaneously, it asserts the open-drain OC pin low to signal the host microcontroller. If the condition persists and junction temperature exceeds 150°C, thermal shutdown disables all outputs until cooling occurs. This dual-layer protection is intrinsic to the TPS2202IDFR's architecture and requires no external components.
Can the TPS2202IDFR support mixed-voltage operation - e.g., 3.3-V card in Slot A and 5-V card in Slot B?
Yes, the TPS2202IDFR supports fully independent voltage selection per slot. AVCC/AVPP and BVCC/BVPP are controlled separately via the 9-bit serial command word, allowing Slot A to deliver 3.3 V while Slot B delivers 5 V - or any combination of 0 V, 3.3 V, 5 V, or 12 V. This capability is explicitly validated in the datasheet's "Terminal Functions" table and "Typical PC-card power-distribution application" schematic. Mixed-voltage operation is a core design requirement met by the TPS2202IDFR, enabling backward compatibility and flexible card mixing in multi-slot hosts.
What is the significance of the "DF" package suffix in TPS2202IDFR?
The "DF" in TPS2202IDFR denotes the Small-Outline Integrated Circuit (SOIC) package variant - distinct from the "DB" (SSOP) package used in TPS2202IDBR. Both share identical pinout, electrical specifications, and thermal characteristics per the datasheet's "AVAILABLE OPTIONS" table. The DF package has wider lead pitch (1.27 mm vs. 0.635 mm) and larger body dimensions, making it more suitable for manual assembly, prototyping, and rework. The TPS2202IDFR is functionally interchangeable with TPS2202IDBR in circuit design - only package handling and PCB footprint differ.
