Product details
Overview
TPS2216ADAPR from Texas Instruments is a dual-channel PC Card power-interface switch IC designed for S-CARD and M-CARD power management in CableCARD™ applications. It integrates 3.3-V/5-V/12-V xVCC and xVPP switching with independent xVPP programming, 60-mΩ (3.3-V) and 140-mΩ (5-V) typical rDS(on), short-circuit/thermal protection, and 150-µA max quiescent current - enabling robust, fuseless power distribution in notebook computers and PDAs.
For engineers reviewing the TPS2216ADAPR datasheet, TPS2216ADAPR pinout, TPS2216ADAPR application, or TPS2216ADAPR equivalent, key selection criteria include its dual-output voltage-programmable architecture, break-before-make switching, standby mode (50-mA current limit), 32-pin TSSOP (DAP) package with PowerPAD™ thermal enhancement, and compliance with PC Card™ standards for legacy PCMCIA host designs.
Technical Context
The TPS2216ADAPR implements two independent high-side power switches per card slot (AVCC/AVPP and BVCC/BVPP), each configurable via serial interface (CLOCK/DATA/LATCH) with MODE-selectable operation. Its internal current monitoring and thermal shutdown (trip at 155°C, 10°C hysteresis) enable autonomous fault response without external circuitry.
It supports three input rails (3.3 V, 5 V, 12 V), delivers up to 750 mA on xVCC outputs and 200 mA on xVPP outputs at TA = 70°C, and features TTL-compatible logic inputs with internal 150-kΩ pullup (STBY, RESET̅) or pulldown (MODE, RESET) resistors - simplifying host controller interfacing in space-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) xVCC (3.3 V) | 60 mΩ typical at TJ = 25°C, 750 mA load - ensures ≤45 mV drop at full current, meeting PCMCIA 3.3-V regulation (±300 mV). |
| rDS(on) xVCC (5 V) | 140 mΩ typical at TJ = 25°C, 750 mA load - enables ≤105 mV drop, compliant with PCMCIA 5-V regulation (±250 mV). |
| xVPP output current | 200 mA continuous at TA = 70°C - sufficient for flash memory programming/erase in PC Cards requiring 12-V Vpp. |
| Quiescent current | 150 µA maximum - minimizes standby power draw in battery-powered hosts like notebooks and PDAs. |
| Standby current limit | 50 mA typical per output - reduces fault energy during sleep modes while preserving system-level diagnostics. |
| Operating temperature | −40°C to +70°C ambient - validated for industrial-grade deployment in portable computing environments. |
| Thermal shutdown | 155°C trip point with 10°C hysteresis - prevents latch-up and permanent damage during sustained overloads. |
Pinout & Package
The TPS2216ADAPR is housed in a 32-pin TSSOP (DAP) package with exposed thermal pad (PowerPAD™), optimized for PCB heat dissipation in high-density laptop motherboard layouts. Pin count and terminal functions match the DB-30 variant but add dedicated ground and supply pins for improved noise immunity and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 32 | 5V Input | Primary 5-V rail input shared across both card slots; must be biased for xVCC switching functionality. |
| 8, 25 | 12V Input | 12-V Vpp programming voltage input; internally routed to AVPP/BVPP outputs when enabled. |
| 10, 11, 12 | AVCC Output | First card's VCC output (3.3 V/5 V/GND/Hi-Z); controlled via serial interface and MODE state. |
| 9 | AVPP Output | First card's Vpp output (3.3 V/5 V/12 V/GND/Hi-Z); programmable independently of AVCC. |
| 21, 22, 23 | BVCC Output | Second card's VCC output; identical control and voltage sourcing capability as AVCC. |
| 24 | BVPP Output | Second card's Vpp output; fully independent timing and voltage selection from BVCC and AVPP. |
| 19 | STBY Input | Active-low logic input that forces all outputs into 50-mA current-limited standby mode; internally pulled high. |
| 20 | OC Output | Open-drain fault indicator; asserts low on overcurrent or overtemperature events for host system diagnostics. |
| 13 | GND | Power ground reference; connects to PCB thermal pad for enhanced thermal conduction. |
| 30 | MODE Input | Selects TPS2216A operation (must be pulled high externally); internal 150-kΩ pulldown ensures safe default. |
Key Features
| Feature | Design Value |
|---|---|
| Independent xVPP programming | Enables separate voltage assignment (3.3 V/5 V/12 V) to AVPP and BVPP outputs - critical for mixed-memory-card configurations. |
| Break-before-make switching | Prevents momentary shorting between voltage rails during output transitions - eliminates cross-conduction risk in multi-rail systems. |
| 3.3-V low-voltage mode | Allows full 3.3-V xVCC switching without 5-V supply present - supports deep-sleep states where only 3.3 V remains active. |
| Internal power-on reset | Ensures deterministic initial state on power-up without external RC network - reduces BOM count and layout complexity. |
| Current-limit reporting via OC pin | Provides real-time fault signaling to host processor, enabling software-based isolation of failed cards without hardware redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card power interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2216ADB(R) | Same functional spec, 30-pin SSOP (DB) package without PowerPAD™; higher thermal resistance (602 mW @ TA=70°C vs 2340 mW). | Suitable for cost-sensitive, lower-power desktop host designs where PCB space allows larger footprint and thermal performance is less critical. | Select TPS2216ADB(R) when board area permits SSOP and peak xVCC load stays below 500 mA continuous. |
| TPS2214A | Single-slot variant (one AVCC/AVPP pair only); lacks BVCC/BVPP outputs and MODE pin; shares same rDS(on) and protection features. | Targeted at embedded systems with only one PC Card slot, such as barcode scanners or legacy industrial controllers. | Choose TPS2214A only when dual-slot capability is unnecessary - avoids paying for unused channels and simplifies firmware. |
Compared with TPS2216ADB(R), the TPS2216ADAPR delivers 3.9× higher power dissipation capability and superior thermal performance due to its PowerPAD™-enhanced TSSOP package; versus TPS2214A, it provides essential dual-slot support required for CableCARD™ and modern PCMCIA host architectures.

FAQ
What is the primary function of the TPS2216ADAPR in PC Card systems?
The TPS2216ADAPR serves as a dual-channel PC Card power-interface switch, managing independent 3.3-V/5-V/12-V VCC and Vpp power delivery to two PC Cards simultaneously. It integrates high-side MOSFETs, current limiting, thermal protection, and serial configuration logic - eliminating discrete components while ensuring PCMCIA compliance and CableCARD™ readiness in notebook and PDA platforms.
Does the TPS2216ADAPR support independent voltage programming for Vpp outputs?
Yes, the TPS2216ADAPR supports fully independent xVPP programming: AVPP and BVPP can be set to 3.3 V, 5 V, or 12 V individually via its serial interface (CLOCK/DATA/LATCH), regardless of their corresponding xVCC settings. This capability is explicitly confirmed in the SLVS267C datasheet Section 1 and Functional Block Diagram, enabling mixed-memory-card configurations common in CableCARD™ applications.
What is the maximum continuous output current supported by the TPS2216ADAPR on its xVCC outputs?
The TPS2216ADAPR supports 750 mA continuous output current per xVCC channel (AVCC and BVCC) at an ambient temperature of 70°C, as specified in the Recommended Operating Conditions table (Section 4, SLVS267C). This rating applies to both 3.3-V and 5-V output configurations and is validated across the full −40°C to +70°C operating range.
How does the TPS2216ADAPR implement thermal protection?
The TPS2216ADAPR incorporates internal thermal shutdown with a trip point of 155°C and 10°C hysteresis, as documented in Section 5 (Electrical Characteristics) of SLVS267C. When junction temperature exceeds 155°C, the device disables all outputs and asserts the OC pin low. Recovery occurs automatically after cooling below 145°C, ensuring robust self-protection without external circuitry.
Is the TPS2216ADAPR pin-compatible with earlier TI PC Card switches like the TPS2202A?
No, the TPS2216ADAPR is not pin-compatible with the TPS2202A. While the datasheet states "The TPS2216A is backward-compatible with the TPS2202A, TPS2206, and TPS2216", this refers to functional compatibility and register mapping - not physical pinout. The TPS2216ADAPR uses a 32-pin TSSOP (DAP) package, whereas the TPS2202A uses a 24-pin SOIC. Direct PCB replacement requires layout revision.
