Product details
Overview
TPS2206ADAPR from Texas Instruments is a dual-slot PC CardBus power-interface switch providing integrated 3.3-V, 5-V, and 12-V switching for two PC Card sockets. It features break-before-make switching, 85-mΩ rDS(on) on 3.3-V VCC paths, thermal shutdown at 135°C, short-circuit current limiting (1–2 A on xVCC, 120–300 mA on xVPP), and P2C 3-lead serial interface compatibility. It is used in notebook computers and PDAs for controlled hot-swap power delivery to PCMCIA cards.
For engineers reviewing the TPS2206ADAPR datasheet, TPS2206ADAPR pinout, TPS2206ADAPR application, or TPS2206ADAPR equivalent, key selection criteria include dual-slot VCC/VPP switching capability, independent 3.3/5/12-V rail control, thermal and overcurrent fault reporting via OC pin, and compatibility with CardBus controllers requiring P2C serial interface timing.
Technical Context
The TPS2206ADAPR implements six independent MOSFET power switches-four for VCC (two per slot) and two for VPP-each with dedicated current-limit sensing and thermal protection. Its P2C serial interface uses CLOCK, DATA, and LATCH signals to configure output states without external address lines.
It supports UVLO with hysteresis (2.4–2.9 V on 3.3-V input; 2.3–2.9 V on 5-V input) and includes internal pullups on SHDN and RESET pins. The device operates across −40°C to 85°C ambient and maintains regulated output voltage drop within PC Card specification limits up to 750 mA per xVCC path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) (3.3-V xVCC) | 85 mΩ typical at 750 mA - enables ≤100 mV drop under full PC Card peak load, meeting 5% regulation requirement |
| rDS(on) (5-V xVCC) | 95 mΩ typical at 500 mA - ensures compliance with PC Card average current and voltage-drop constraints |
| xVCC short-circuit limit | 1–2 A steady-state - protects host power rails during card insertion faults without fuse replacement |
| xVPP short-circuit limit | 120–300 mA - safely handles flash programming loads while preventing damage to 12-V supply |
| Thermal shutdown threshold | 135°C rising, 125°C hysteresis - autonomously disables all outputs during sustained overload or poor heatsinking |
| Logic supply range | 3.3 V required; 5 V and 12 V optional - allows partial operation if only one supply is present |
| Serial interface clock | 2.5 MHz max - compatible with standard CardBus controller timing without added delay logic |
Pinout & Package
TPS2206ADAPR is housed in a 32-pin PowerPAD™ TSSOP (DAP) package with exposed thermal pad for enhanced heat dissipation. Pin count and layout match the TPS2206A DAP variant specified in SLVS449A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 32 | 5V Input | Supplies 5-V rail to internal switches; must be present for 5-V card operation |
| 8, 25 | 12V Input | Provides 12-V VPP for flash programming; both pins require external connection |
| 16, 17, 18 | 3.3V Input | Primary chip power and 3.3-V card rail source; UVLO triggers Hi-Z if below 2.4 V |
| 10, 11, 12 | AVCC Output | Switched 3.3/5/12-V output for Card A VCC; supports up to 750 mA |
| 9 | AVPP Output | Switched 3.3/5/12-V output for Card A VPP; rated for 50 mA continuous |
| 21, 22, 23 | BVCC Output | Switched 3.3/5/12-V output for Card B VCC; identical rating to AVCC |
| 24 | BVPP Output | Switched 3.3/5/12-V output for Card B VPP; identical rating to AVPP |
| 4 | CLOCK Input | Serial interface clock; synchronizes DATA sampling on rising edge |
| 3 | DATA Input | Serial command/data line; controls individual switch enable/disable states |
| 5 | LATCH Input | Edge-triggered strobe; latches DATA word into configuration register |
| 26 | SHDN Input | Asynchronous active-low shutdown; forces all outputs to Hi-Z state |
| 20 | OC Output | Open-drain overcurrent flag; sinks current when any xVCC/xVPP exceeds limit |
| 14 | RESET Input | Active-low system reset; initializes all switches to safe Hi-Z state on power-up |
| 13 | GND | Power and signal reference; connects to thermal pad for optimal thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents cross-conduction between VCC and VPP rails during state transitions, eliminating shoot-through risk in dual-voltage card slots |
| Dual-slot independent control | Enables asymmetric power sequencing - e.g., powering Card A at 3.3 V while Card B runs at 5 V - without shared control logic |
| Integrated current-limit reporting | OC pin provides real-time fault indication to host controller, enabling software-initiated diagnostics instead of hardware fuse replacement |
| Thermal shutdown with hysteresis | 10°C hysteresis prevents oscillation near trip point, ensuring stable recovery after transient overload or ambient temperature rise |
| P2C 3-wire serial interface | Reduces host GPIO count vs parallel control; eliminates need for address decoding logic or additional level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-slot PC Card power-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2206ADB | 30-pin SSOP (DB) package; no exposed thermal pad; lower power dissipation rating (821 mW vs 3191 mW at 25°C) | Suitable for lower-power, cost-sensitive designs where thermal headroom is adequate and board area permits larger footprint | Select TPS2206ADB when thermal management is handled externally and PCB layout favors SSOP over TSSOP. |
| TPS2226A | Independent VPP switching per slot; MODE pin enables VPP control granularity not present in TPS2206ADAPR | Required when Card A and Card B need separate VPP enable/disable control (e.g., mixed flash/NAND card configurations) | Choose TPS2226A only if per-slot VPP independence is mandatory; otherwise TPS2206ADAPR offers simpler control and lower BOM count. |
Compared with TPS2206ADB, TPS2206ADAPR delivers 3.9× higher thermal power handling and smaller footprint; versus TPS2226A, it trades per-slot VPP flexibility for reduced pin count and simplified serial command structure.

FAQ
What is the function of the OC pin on the TPS2206ADAPR?
The OC (Overcurrent) pin on the TPS2206ADAPR is an open-drain output that pulls low whenever any xVCC or xVPP output exceeds its respective current limit. It requires an external pullup resistor and provides real-time fault signaling to the host controller, enabling diagnostics and user alerts without interrupting system operation. This behavior is confirmed in the Electrical Characteristics table and Figure 5 of SLVS449A.
Does the TPS2206ADAPR support independent control of each PC Card slot's VPP voltage?
No, the TPS2206ADAPR does not support independent VPP control per slot. Both AVPP and BVPP outputs are controlled simultaneously by the same serial command bit. Independent VPP switching is available only in variants like TPS2226A and TPS2226A, as explicitly stated in the Available Options table of SLVS449A.
What is the maximum continuous output current supported by the TPS2206ADAPR on its xVPP outputs?
The TPS2206ADAPR supports a maximum continuous output current of 100 mA on each xVPP output (AVPP and BVPP), as defined in the Recommended Operating Conditions table. Short-circuit current limits range from 120 mA to 300 mA depending on junction temperature, but sustained operation above 100 mA violates the device's thermal design envelope per Figure 34.
Can the TPS2206ADAPR operate with only a 3.3-V supply present?
Yes, the TPS2206ADAPR can operate with only the 3.3-V supply applied to pins 16–18, as VI(3.3V) is required for all circuit operations per the Recommended Operating Conditions table. The 5-V and 12-V supplies are only needed when powering cards requiring those voltages; absence of either does not impair basic functionality or serial interface operation.
How does the TPS2206ADAPR implement break-before-make switching between VCC and VPP rails?
The TPS2206ADAPR enforces break-before-make timing through internal state-machine sequencing: when transitioning between VCC and VPP states on the same slot, it first disables the currently active rail, waits for discharge (via internal 0.2–0.5 kΩ discharge resistors), then enables the target rail. This prevents simultaneous conduction, as verified by the "Break-Before-Make Switching" feature statement and discharge resistance specs in the Electrical Characteristics table.
