Product details
Overview
TPS2216ADAP from Texas Instruments is a dual-channel PC Card power-interface switch IC designed for S-CARD and M-CARD power management in CableCARD™ systems. It integrates two independent xVCC/xVPP switching paths, supports 3.3-V/5-V/12-V input distribution, delivers ≤750 mA per xVCC channel and ≤200 mA per xVPP channel at 70°C, features 60-mΩ typical rDS(on) on 3.3-V xVCC switches, and includes short-circuit and thermal protection for notebook and desktop PC Card slots.
For engineers reviewing the TPS2216ADAP datasheet, TPS2216ADAP pinout, TPS2216ADAP application, or TPS2216ADAP equivalent, this page provides verified technical context, exact pin functions for the 32-pin TSSOP (DAP) package, real-world current-limiting behavior, standby-mode current limits, and validated alternatives for PC Card power interface redesigns requiring backward compatibility with TPS2216-series legacy systems.
Technical Context
The TPS2216ADAP implements break-before-make switching across two independent card power channels (A and B), each with separate xVCC (3.3 V/5 V) and xVPP (3.3 V/5 V/12 V) outputs controlled via serial interface (CLOCK/DATA/LATCH) or direct logic inputs. Its MODE pin must be pulled high for full TPS2216A functionality, enabling independent xVPP programming and 3.3-V low-voltage mode operation without 5-V bias.
Internal current limiting operates at 750 mA (xVCC) and 200 mA (xVPP) under normal conditions, dropping to 50 mA in STBY mode; overcurrent detection triggers OC pin assertion within 16–100 µs depending on switch type, while thermal shutdown activates at 155°C with 10°C hysteresis. The device meets PC Card™ standards and supports CableCARD™ power sequencing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) xVCC (3.3 V) | 60 mΩ typical at TJ = 25°C, IO = 750 mA - enables ≤45 mV drop at 750 mA, meeting PCMCIA 5% regulation for 3.3-V outputs. |
| rDS(on) xVCC (5 V) | 140 mΩ typical at TJ = 25°C, IO = 750 mA - yields ≤105 mV drop at 750 mA, compliant with 5-V ±250 mV regulation limit. |
| xVPP Switch rDS(on) | 0.7 Ω typical at TJ = 25°C, IO = 50 mA - supports 12-V flash programming with <35 mV drop at 50 mA load. |
| Standby Current Limit | 50 mA typical per output - reduces fault current during sleep modes, minimizing battery drain in portable systems. |
| Quiescent Current | 150 µA maximum - ensures minimal system power draw when no cards are inserted or powered. |

| Package | 32-pin TSSOP (DAP) with PowerPAD - provides enhanced thermal dissipation (4255 mW at TA = 25°C) vs. DB package. |
Pinout & Package
TPS2216ADAP is housed in a 32-pin TSSOP (DAP) package with exposed thermal pad (PowerPAD™). Pin numbering follows top-view orientation; pins 3, 15, 26–29, and 31 are NC (no internal connection). The PowerPAD must be soldered to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 32 | 5V Input | Accepts 2.7–5.25 V supply for 5-V xVCC/xVPP switching; must be biased for switch operation. |
| 8, 25 | 12V Input | Accepts 2.7–13.5 V for 12-V xVPP output; both 12V pins must be connected together per datasheet. |
| 10, 11, 12 | AVCC Output | 3.3-V/5-V/GND/high-Z output for Card A VCC; supports up to 750 mA continuous at 70°C. |
| 9 | AVPP Output | 3.3-V/5-V/12-V/GND/high-Z output for Card A VPP; supports up to 200 mA continuous at 70°C. |
| 21, 22, 23 | BVCC Output | 3.3-V/5-V/GND/high-Z output for Card B VCC; identical rating and control to AVCC. |
| 24 | BVPP Output | 3.3-V/5-V/12-V/GND/high-Z output for Card B VPP; identical rating and control to AVPP. |
| 30 | MODE Input | Must be pulled high externally (≥2 V) to enable TPS2216A functionality; internally pulldown 150-kΩ. |
| 19 | STBY Input | Active-low logic input; pulls high internally (150-kΩ) - asserts 50-mA current limit on all outputs when low. |
| 20 | OC Output | Open-drain logic-low alert on overcurrent or overtemperature; requires external pullup for host monitoring. |
| 13 | GND | Primary ground reference; connects to PowerPAD thermal pad for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Independent xVPP Programming | Enables separate voltage selection (3.3 V/5 V/12 V) for each card's VPP output via serial interface, critical for mixed-memory-card systems. |
| 3.3-V Low-Voltage Mode | Allows full xVCC switching using only 3.3-V supply - eliminates need for 5-V rail in sleep states, reducing system power overhead. |
| Break-Before-Make Switching | Prevents cross-conduction between voltage rails during state transitions, avoiding bus contention and latch-up in multi-rail PC Card slots. |
| Internal Power-On Reset | Ensures defined initial state on power-up without external reset circuitry, simplifying host design and improving boot reliability. |
| Serial Interface Control | Supports CLOCK/DATA/LATCH protocol for dynamic configuration of both card channels, enabling runtime reconfiguration without GPIO expansion. |

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) | 24-pin SSOP (DB) package; lower thermal dissipation (1095 mW at TA = 25°C); same pinout mapping for shared signals but different pin count and NC placement. | Limited to space-constrained designs where PowerPAD thermal enhancement is unnecessary; not suitable for high-ambient or high-power-density layouts. | Select TPS2216ADB(R) only if board layout uses DB footprint and thermal budget permits lower power handling. |
| TPS2214ADAP(R) | Single-channel variant (one AVCC/AVPP pair only); lacks BVCC/BVPP outputs and associated control pins (e.g., no second LATCH/CLOCK path). | Applicable only to single-slot systems; cannot replace TPS2216ADAP in dual-card host designs without hardware redesign. | Choose TPS2214ADAP(R) only for cost-sensitive single-card applications where dual-channel capability is unused. |
Compared with TPS2216ADB(R), the TPS2216ADAP offers 3.9× higher thermal power rating and PowerPAD grounding; compared with TPS2214ADAP(R), it provides full dual-channel control essential for CableCARD™ and dual-slot PCMCIA hosts - neither alternative supports pin-compatible replacement without layout or firmware changes.

FAQ
What is the function of the MODE pin on the TPS2216ADAP?
The MODE pin on the TPS2216ADAP must be pulled high externally to enable full TPS2216A functionality, including independent xVPP programming and 3.3-V low-voltage mode. When floating or pulled low, the device defaults to TPS2206-compatible operation. An internal 150-kΩ pulldown resistor ensures defined behavior if left unconnected, but TPS2216ADAP requires explicit high bias for intended dual-channel operation.
Does the TPS2216ADAP support hot-plug insertion of PC Cards?
Yes, the TPS2216ADAP supports hot-plug operation through its integrated current limiting and break-before-make switching architecture. When a card is inserted, the device limits inrush current and prevents bus contention; overcurrent events trigger the OC pin within 16–100 µs and reduce output current to safe levels, protecting both the host and card. This behavior is validated per PC Card Standard timing and fault-response requirements.
What is the maximum continuous output current for xVPP on the TPS2216ADAP?
The TPS2216ADAP supports a maximum continuous xVPP output current of 200 mA at TA = 70°C, as specified in the Recommended Operating Conditions table. This applies to all xVPP outputs (AVPP and BVPP) regardless of selected voltage (3.3 V, 5 V, or 12 V). At elevated junction temperatures, the current limit remains fixed but voltage drop increases due to rising rDS(on), requiring careful thermal design in high-power applications.
How does the STBY pin affect the TPS2216ADAP's current-limiting behavior?
When the STBY pin on the TPS2216ADAP is driven low, all xVCC and xVPP outputs enter standby mode with current limits reduced to 50 mA typical. This mode is active-low and internally pulled high with a 150-kΩ resistor. In STBY, the device maintains full logic control and output voltage regulation but restricts fault current to minimize battery drain and PCB heating during idle or maintenance states.
Is the TPS2216ADAP pin-compatible with earlier TPS2216 variants?
Yes, the TPS2216ADAP is backward-compatible with the TPS2216 (non-A suffix) and shares identical pinout and functionality with the TPS2216A family. It replaces TPS2216ADB(R) in the DAP package without requiring PCB changes, retaining all signal assignments, NC placements, and PowerPAD grounding requirements. Texas Instruments explicitly confirms this compatibility in the datasheet's "Available Options" section.
