Product details
Overview
TPS2223PWP from Texas Instruments is a dual-slot PC Card power-interface switch IC designed for notebook and desktop computers. It provides fully integrated 3.3 V and 5 V switching (no 12 V) to two card slots, features break-before-make switching, thermal/short-circuit protection, and 140-µA typical quiescent current at 3.3 V input. It meets PC Card standards and supports independent VPP/VCC control.
For engineers reviewing the TPS2223PWP datasheet, TPS2223PWP pinout, TPS2223PWP application, or TPS2223PWP equivalent, key selection criteria include its 24-pin HTSSOP PowerPAD® package, absence of 12-V support, 110 mΩ typical rDS(on) for 3.3V→xVCC, 130 mΩ for 5V→xVCC, and open-drain OC fault reporting with 3 µs response on xVPP overcurrent.
Technical Context
The TPS2223PWP implements dual-channel power switching logic with independent control of AVCC/BVCC (3.3 V/5 V outputs) and AVPP/BVPP (VPP outputs), though 12 V is disabled per datasheet. Its internal current-limit circuitry delivers 1 A steady-state short-circuit protection on xVCC paths and 200 mA on xVPP paths, with thermal shutdown triggered at 135°C junction temperature and 10°C hysteresis.
Control is executed via TTL-compatible serial interface (DATA/CLOCK/LATCH) and asynchronous pins (SHDN, RESET). Power-on reset (POR) asserts internal reset when 3.3 V input falls below 1.7 V, while undervoltage lockout (UVLO) disables all switches if VI(3.3V) drops below 2.7 V (typical) with 100 mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) 3.3V→xVCC | 110 mΩ typical - ensures ≤82.5 mV drop at 750 mA, meeting PC Card 5% regulation for 5 V output |
| rDS(on) 5V→xVCC | 130 mΩ typical - limits voltage drop to ≤65 mV at 500 mA, supporting regulated 5 V delivery |
| Short-circuit limit xVCC | 1.4 A typical - protects host power rails and PCB traces during card faults without external fuses |
| Short-circuit limit xVPP | 200 mA typical - matches flash-programming current requirements while preventing damage |
| Quiescent current | 140 µA typical at 3.3 V - enables low-power standby in battery-operated systems like PDAs |
| Operating temp range | −40°C to +85°C ambient - validated for industrial-grade embedded computing environments |
| OC response time | 3 µs for xVPP overcurrent - enables fast isolation before fault energy propagates |
Pinout & Package
TPS2223PWP is housed in a 24-pin HTSSOP PowerPAD® package (PWP-24), thermally enhanced with an exposed die paddle for improved heat dissipation in high-current applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 24 | 5V Input | Primary 5 V supply input for both card slots; must be ≥3 V for operation |
| 13, 14 | 3.3V Input | Mandatory 3.3 V supply for chip logic and card power; powers all internal circuitry |
| 9, 10, 17, 18 | AVCC / BVCC Outputs | Switched 3.3 V/5 V outputs to Slot A and Slot B; Hi-Z when disabled |
| 8, 19 | AVPP / BVPP Outputs | VPP outputs for Slot A/B; limited to 3.3 V/5 V only (no 12 V on TPS2223) |
| 11 | GND | Power ground reference; connects to PCB ground plane under PowerPAD |
| 15 | OC | Open-drain overcurrent flag; pulls low within 3 µs on xVPP fault, requires external pullup |
| 21 | SHDN | Asynchronous active-low shutdown; places all outputs in Hi-Z state |
| 12 | RESET | Active-low reset input; forces internal reset and opens all switches |
| 3, 4, 5 | DATA / CLOCK / LATCH | Serial interface for configuration; supports pin-level control of individual switches |
| 6, 7, 16, 20, 22, 23 | NC | No internal connection; pins 7 and 20 are NC specifically for TPS2223 |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between VCC and VPP supplies during state transitions, eliminating cross-conduction risk |
| Independent VPP/VCC control | Enables selective activation of programming voltage (VPP) without powering main VCC rail, reducing system power overhead |
| Integrated thermal shutdown | 135°C trip point with 10°C hysteresis prevents latch-up and permanent damage during sustained overload |
| Power-on reset (POR) | Asserts internal reset when 3.3 V input rises above 1.7 V, ensuring deterministic startup sequence |
| UVLO on 3.3 V input | Disables all switches if VI(3.3V) falls below 2.7 V (typ), protecting against brownout-induced misoperation |

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 |
|---|---|---|---|
| TPS2223DB | Same functionality and pinout, but in 24-pin SSOP (DB-24) package without PowerPAD® thermal enhancement | Limited power dissipation capability; unsuitable for sustained 750 mA loads at elevated ambient temperatures | Select TPS2223DB only for cost-sensitive, low-power, or space-constrained layouts where thermal performance is secondary |
| TPS2214A | Pin-compatible predecessor; supports same 3.3 V/5 V switching but lacks serial interface and has higher 250 µA quiescent current | No DATA/CLOCK/LATCH control; relies solely on dedicated SHDN/RESET pins for global control | Choose TPS2214A for simpler designs requiring basic on/off control without per-slot programmability |
Compared with TPS2223DB and TPS2214A, the TPS2223PWP offers superior thermal performance via PowerPAD®, lower quiescent current, and flexible serial configuration-making it optimal for high-reliability, multi-slot, battery-powered hosts.

FAQ
What is the maximum continuous output current supported by TPS2223PWP on its xVCC channels?
The TPS2223PWP supports up to 750 mA per xVCC channel (AVCC/BVCC) at TJ = 25°C, with current limiting set to 1.4 A typical for short-circuit protection. At TJ = 100°C, the safe continuous current remains 750 mA due to internal thermal derating, verified per recommended operating conditions in the SLVS317 datasheet.
Does TPS2223PWP support 12 V switching on its VPP outputs?
No, TPS2223PWP does not support 12 V switching on AVPP or BVPP outputs. The datasheet explicitly states "Optimized for lower power implementation, the TPS2223 does not support 12-V switching to VPP" and confirms pins 7 and 20 are NC for this device. Only TPS2224 and TPS2226 support 12 V on VPP.
What is the function of the OC pin on TPS2223PWP, and what is its response time?
The OC pin on TPS2223PWP is an open-drain overcurrent reporting output that pulls low during fault conditions. For xVPP overcurrent, its response time is 3 µs from fault onset to OC signal falling edge; for xVCC, it is 10 µs. An external pullup resistor is required, and the pin sinks up to 10 mA per absolute maximum ratings.
How does the TPS2223PWP handle undervoltage conditions on its 3.3 V input pin?
The TPS2223PWP implements undervoltage lockout (UVLO) on the 3.3 V input: all switches enter Hi-Z state when VI(3.3V) falls below 2.7 V (typical), with 100 mV hysteresis. This prevents erratic behavior during brownout and ensures clean power-up when voltage recovers above 2.8 V.
Is TPS2223PWP pin-compatible with TPS2223DB, and what are the key mechanical differences?
Yes, TPS2223PWP and TPS2223DB are pin-compatible 24-pin devices with identical pin functions and assignments. The primary difference is packaging: TPS2223PWP uses a thermally enhanced HTSSOP PowerPAD® package (PWP-24), while TPS2223DB uses standard SSOP (DB-24) without the exposed thermal pad-resulting in significantly lower power dissipation capability.
