Product details
Overview
TPS2205IDAPR from Texas Instruments is a dual-slot PC Card power-interface switch IC that integrates VCC and Vpp switching for 3.3-V, 5-V, and 12-V card power distribution. It delivers 1 A continuous at 3.3 V and 1 A at 5 V per slot, features break-before-make switching, 140-mΩ 5-V VCC rDS(on), and thermal/overcurrent protection. It enables compliant power management in notebook computers and PDAs.
For engineers reviewing the TPS2205IDAPR datasheet, TPS2205IDAPR pinout, TPS2205IDAPR application, or TPS2205IDAPR equivalent, key selection considerations include dual-slot VCC/Vpp switching capability, 3.3-V low-voltage mode operation without 5-V input, integrated overcurrent reporting (OC pin), shutdown control (SHDN), and compatibility with PCMCIA-compliant controllers from Intel, TI, Cirrus, Ricoh, and O2Micro.
Technical Context
The TPS2205IDAPR implements two independent high-side power switches per slot-one for VCC (3.3 V/5 V) and one for Vpp (3.3 V/5 V/12 V)-with logic-controlled enable inputs (A/B_VCC3, A/B_VCC5, A/B_VPP_PGM, A/B_VPP_VCC). Its LinBiCMOS process enables internal charge-pump gate drive, eliminating need for external 12-V bias during normal operation.
It supports PCMCIA-compliant voltage transitioning: initial 5-V power-up followed by 3.3-V negotiation, with automatic discharge of VCC capacitors below 0.8 V before reapplication. The OC output provides real-time overcurrent flagging, while SHDN forces all outputs to high-impedance state with ≤1 µA quiescent current.

Pinout & Package
TPS2205IDAPR is housed in a 32-pin TSSOP (DAP) package with exposed thermal pad. Pin functions are validated per TI SLVS128E datasheet Rev. January 2001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3.3V (pins 16,17,18) | 3.3-V VCC input supply | Primary bias source in low-voltage mode; powers internal logic and 3.3-V switches |
| 5V (pins 1,2,32) | 5-V VCC input supply | Enables lower rDS(on) for 3.3-V and 5-V switching; supplies charge pump for 12-V Vpp drive |
| 12V (pins 8,25) | 12-V Vpp input supply | Only required during flash programming; otherwise can be disabled to extend battery life |
| A_VCC3 / A_VCC5 (pins 7,6) | Slot A VCC control inputs | Logic-selectable 3.3-V or 5-V output on AVCC pins (10,11,12); determines VCC rail delivered to Card A |
| A_VPP_PGM / A_VPP_VCC (pins 4,5) | Slot A Vpp control inputs | Selects 12-V (programming) or 3.3/5-V (standby) output on AVPP (pin 9); enables PCMCIA-compliant voltage sequencing |
| B_VCC3 / B_VCC5 (pins 26,28) | Slot B VCC control inputs | Independent logic control for BVCC outputs (21,22,23); supports mixed-voltage dual-card operation |
| B_VPP_PGM / B_VPP_VCC (pins 30,29) | Slot B Vpp control inputs | Enables independent Vpp configuration per slot-critical for cards requiring different programming voltages |
| SHDN (pin 14) | Global shutdown input | Active-low signal forcing all AVCC/BVCC/AVPP/BVPP outputs to high-impedance; reduces ICC to ≤1 µA |
| OC (pin 20) | Overcurrent fault output | Open-drain logic-low assertion during overcurrent; connects directly to host microcontroller interrupt line |
| GND (pin 13) | Power ground reference | Single ground return for all power paths; requires low-impedance PCB connection to minimize noise and voltage error |
Key Features
| Feature | Design Value |
|---|---|
| 3.3-V Low-Voltage Mode | Operates fully with only 3.3-V input (VI(5V) = 0); eliminates dependency on 5-V rail for sleep/pager modes |
| Integrated Charge Pump | Generates internal gate-drive voltage from 3.3-V or 5-V input; removes need for always-on 12-V supply |
| PCMCIA-Compliant Sequencing | Supports mandatory VCC discharge to <0.8 V before reapplication; satisfies JEIDA/PCMCIA voltage-transitioning requirements |
| No External Fuses Required | Current-limiting sense FETs replace fuses-reducing BOM count, improving reliability, and avoiding manual replacement |
| Dual Independent Slot Control | Separate VCC/Vpp enable logic per slot allows asymmetric configurations (e.g., Card A = 3.3 V, Card B = 5 V + 12 V) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card power-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2201IDBR | 32-pin SSOP; includes VDD pin and APWR_GOOD/BPWR_GOOD status outputs; no 3.3-V-only mode | Requires 5-V bias; lacks low-power shutdown and 3.3-V-first sequencing support | Choose only if legacy TPS2201 footprint compatibility is mandatory and 3.3-V-only operation is unnecessary. |
| MAX1683EEE+ | 16-pin QSOP; single-slot only; 3.3-V/5-V VCC only (no Vpp switching); no OC output | Cannot support 12-V flash programming or dual-slot configurations | Select only for cost-sensitive single-slot designs where Vpp functionality and fault reporting are omitted. |
Compared with TPS2205IDAPR, TPS2201IDBR lacks 3.3-V low-voltage mode and requires external 5-V bias, while MAX1683EEE+ omits Vpp switching and dual-slot capability-making TPS2205IDAPR the only option supporting full PCMCIA-compliant dual-slot, mixed-voltage, and battery-optimized operation.

FAQ
What is the maximum continuous output current per VCC channel on the TPS2205IDAPR?
The TPS2205IDAPR delivers up to 1 A continuously per VCC channel (AVCC or BVCC) at both 3.3 V and 5 V, verified across −40°C to 85°C ambient temperature. At 5 V, this meets the PCMCIA 700 mA regulation requirement with margin; at 3.3 V, it supports full 1 A within 300 mV regulation tolerance. The TPS2205IDAPR achieves this using low rDS(on) switches (110 mΩ typical at 3.3 V).
Does the TPS2205IDAPR support true 3.3-V-only operation without any 5-V supply?
Yes, the TPS2205IDAPR supports full 3.3-V-only operation (VI(5V) = 0). In this mode, bias current is derived solely from the 3.3-V input pins, enabling use in sleep or pager modes where only 3.3 V is available. The TPS2205IDAPR maintains all control logic, shutdown, and OC reporting functionality-though 3.3-V VCC rDS(on) increases to 180 mΩ max.
How does the TPS2205IDAPR handle overcurrent conditions?
The TPS2205IDAPR uses internal sense FETs-not external resistors-to monitor each VCC and Vpp output. During overcurrent, it linearly limits output current rather than latching off, preventing system disruption. Simultaneously, it asserts the open-drain OC pin low to signal the host controller. If sustained, thermal shutdown disables all outputs until junction temperature falls below safe threshold.
Can the TPS2205IDAPR be used in new designs despite its 2001 datasheet revision date?
Yes, the TPS2205IDAPR remains actively manufactured and supported by Texas Instruments for legacy PC Card applications. Its design satisfies all PCMCIA 2.0/3.0 power specifications, and Aetrix Electronics guarantees traceable, factory-fresh stock with full lifecycle coordination-including notification of any future discontinuation per TI's Product Change Notifications.
What is the purpose of the SHDN pin on the TPS2205IDAPR?
The SHDN (shutdown) pin on the TPS2205IDAPR is an active-low input that places all AVCC, BVCC, AVPP, and BVPP outputs into high-impedance state when asserted. In shutdown mode, total supply current drops to ≤1 µA-enabling ultra-low-power system states. The TPS2205IDAPR retains pin compatibility and functional behavior with SHDN across all operating modes, including 3.3-V-only operation.
