Product details
Overview
TPS2216DBR from Texas Instruments is a dual-channel PC Card power-interface switch IC that integrates two independent xVCC and two xVPP switching paths for 3.3-V, 5-V, and 12-V power distribution to PC Cards. It delivers 1-A continuous xVCC output current at 5 V/3.3 V, features 60-mΩ typical rDS(on) for xVCC switches, includes break-before-make switching, thermal shutdown at 155°C, and supports TTL-logic-compatible control inputs. It is used in notebook computers and PDAs for hot-plug power management.
For engineers reviewing the TPS2216DBR datasheet, TPS2216DBR pinout, TPS2216DBR application, or TPS2216DBR equivalent, key selection criteria include its dual-card support, independent xVPP programming, 3.3-V low-voltage mode (enabling operation without 5-V supply), standby-mode 50-mA current limiting, and compliance with PC Card™ standards.
Technical Context
The TPS2216DBR implements fully integrated MOSFET-based power switching with internal current sensing and thermal monitoring. Its logic-controlled serial interface (CLOCK/DATA/LATCH) enables programmable xVPP output selection independent of xVCC, while MODE pin configuration determines compatibility with TPS2206 or TPS2216 operation modes.
It features internal power-on reset, active-low STBY input for 50-mA standby current limiting, OC fault-reporting output, and dual independent overcurrent protection circuits-one per xVCC channel and one per xVPP channel-with response times of 100 µs (xVCC) and 16 µs (xVPP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) xVCC | 60 mΩ typical at TJ = 25°C, IO = 1 A - ensures ≤60 mV drop at 1 A for tight 5% regulation compliance on 5-V outputs. |
| xVCC Output Current | 1 A continuous per channel at TA = 70°C - supports full-power PC Card operation without external current limiting. |
| xVPP Output Current | 200 mA continuous per channel at TA = 70°C - sufficient for flash memory programming/erase voltage delivery. |
| Quiescent Current | 150 µA maximum - enables low-power system sleep states where only 3.3-V rail remains active. |
| Standby Current Limit | 50 mA typical - reduces fault energy during card insertion/removal and simplifies host-side fault isolation. |
| Thermal Shutdown | 155°C trip point with 10°C hysteresis - protects against sustained overload or poor heatsinking in compact laptop designs. |
| Logic Compatibility | TTL-input thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V) - interfaces directly with standard 3.3-V/5-V microcontrollers without level-shifting. |
Pinout & Package
TPS2216DBR is housed in a 30-pin SSOP (DB) package with exposed pad not connected internally. Pin assignments are optimized for PC Card connector routing, supporting dual-card power sequencing and fault reporting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3.3V (15,16,17) | Input supply | Provides 3.3-V source for card power and internal logic when 5-V is absent - enables true 3.3-V-only low-power mode. |
| 5V (1,2,30) | Input supply | Primary 5-V input for xVCC/xVPP switching; required for full 5-V/12-V operation and internal biasing. |
| 12V (7,24) | Input supply | Dual 12-V inputs tied together per datasheet - supplies VPP for flash programming; must be externally connected. |
| AVCC (9,10,11), BVCC (20,21,22) | Output | Two independent 3.3-V/5-V/GND/high-Z xVCC outputs - drive VCC pins of Slot A and Slot B PC Cards separately. |
| AVPP (8), BVPP (23) | Output | Two independent 3.3-V/5-V/12-V/GND/high-Z xVPP outputs - deliver programming voltage to Slot A and Slot B cards. |
| MODE (29) | Configuration input | Must be pulled high externally for TPS2216 operation; floating or low configures TPS2206-compatible mode. |
| STBY (19) | Control input | Active-low input enabling 50-mA standby current limit - used during card insertion detection or suspend states. |
| OC (18) | Fault output | Open-drain logic-low signal on overcurrent or overtemperature - provides immediate host interrupt for fault isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Independent xVPP programming | Each xVPP output can be set to 3.3 V, 5 V, or 12 V independently via serial interface - eliminates need for external voltage-select jumpers per slot. |
| 3.3-V low-voltage mode | Operates fully with only 3.3-V supply applied - enables power management in deep-sleep states where 5-V rail is disabled. |
| Break-before-make switching | Prevents momentary short between VCC/VPP rails during reconfiguration - avoids bus contention and latch-up in multi-rail systems. |
| Internal power-on reset | Ensures known initial state on power-up without external RC network - reduces BOM count and improves reliability in portable systems. |
| PC Card™ compliance | Meets timing, voltage regulation, and sequencing requirements of PCMCIA specification - guarantees interoperability with certified PC Cards and hosts. |

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 |
|---|---|---|---|
| TPS2216DAPR | Identical functionality and pinout but in thermally enhanced 32-pin PowerPAD™ TSSOP (DAP) package with 4.255 W power rating vs. DB's 1.095 W. | Preferred for higher ambient temperature or higher continuous power dissipation requirements (e.g., industrial enclosures). | Select TPS2216DAPR when board-level thermal management is constrained and >1 W continuous dissipation is expected. |
| TPS2206DBR | Lacks 3.3-V low-voltage mode and independent xVPP programming; MODE pin floating defaults to TPS2206 behavior; no STBY pin. | Suitable only for legacy 5-V-only PC Card systems without low-power sleep requirements. | Choose TPS2206DBR only if backward compatibility with older designs is mandatory and 3.3-V-only operation is unnecessary. |
Compared with TPS2216DAPR, the TPS2216DBR offers lower thermal performance but fits legacy SSOP footprints; compared with TPS2206DBR, it adds critical low-power and configurability features essential for modern portable systems.

FAQ
What is the maximum continuous output current supported by each xVCC channel of the TPS2216DBR?
The TPS2216DBR supports 1 A continuous output current per xVCC channel (AVCC and BVCC) at TA = 70°C, as specified in the recommended operating conditions. This rating holds for both 3.3-V and 5-V output configurations and is validated across the full −40°C to 125°C junction temperature range with appropriate PCB thermal design. The TPS2216DBR achieves this with 60-mΩ typical rDS(on), ensuring minimal voltage drop under load.
Does the TPS2216DBR support operation using only a 3.3-V supply, without 5-V present?
Yes, the TPS2216DBR supports true 3.3-V-only operation via its dedicated 3.3-V low-voltage mode. When the 5-V supply is absent, the device uses the 3.3-V input (pins 15–17) to power internal logic and drive xVCC outputs at 3.3 V. This capability is explicitly confirmed in the datasheet description and enables low-power sleep modes in notebook and PDA designs where the 5-V rail is shut down.
How does the MODE pin affect the functionality of the TPS2216DBR?
The MODE pin (pin 29) determines operational mode: it must be pulled high externally for full TPS2216DBR functionality, including independent xVPP programming and STBY control. If left floating or pulled low, the device defaults to TPS2206-compatible behavior-losing xVPP independence and standby mode. The internal 150-kΩ pulldown resistor ensures safe default behavior, but correct TPS2216DBR operation requires explicit external pull-up.
What protection features are integrated into the TPS2216DBR?
The TPS2216DBR integrates short-circuit protection (1–2.2 A xVCC limit, 250–500 mA xVPP limit), thermal shutdown (155°C trip, 10°C hysteresis), and overcurrent fault reporting via the open-drain OC pin. Each xVCC and xVPP channel has independent current limiting, with response times of 100 µs (xVCC) and 16 µs (xVPP). These protections eliminate the need for external fuses and simplify system-level fault handling in portable platforms.
Is the TPS2216DBR pin-compatible with any earlier-generation devices?
The TPS2216DBR is backward-compatible with the TPS2202A and TPS2206 in functional operation but not pin-compatible due to differences in control logic and pin assignments. Specifically, the TPS2216DBR introduces new pins (e.g., STBY, MODE) and reassigns others versus the TPS2206. While software and system architecture may reuse design concepts, PCB layout requires revision to accommodate the TPS2216DBR's 30-pin SSOP footprint and updated signal mapping.
