Product details
Overview
TPS2216ADB 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 independent 3.3-V/5-V xVCC and 3.3-V/5-V/12-V xVPP switching with break-before-make operation, 60-mΩ typical rDS(on) for 3.3-V xVCC, 140-mΩ for 5-V xVCC, and thermal/short-circuit protection - enabling robust hot-swap power control in notebook computers and PDAs.
For engineers reviewing the TPS2216ADB datasheet, TPS2216ADB pinout, TPS2216ADB application, or TPS2216ADB equivalent, key selection criteria include its dual-output programmable VPP/VCC architecture, 150-µA max quiescent current, 50-mA standby current limit, 30-pin SSOP (DB) package, and compliance with PC Card™ standards for legacy add-in card power delivery.
Technical Context
The TPS2216ADB implements two independent high-side power switches per channel (AVCC/AVPP and BVCC/BVPP), each controlled via serial interface (CLOCK/DATA/LATCH) with MODE-selectable configuration. Its internal current monitoring and thermal shutdown circuitry trigger OC output assertion at 155°C junction temperature with 10°C hysteresis.
It supports three input voltage rails (3.3 V, 5 V, 12 V), enables xVPP programming independent of xVCC, and features internal 150-kΩ pullup on STBY/RESET (active-low) and pulldown on MODE - requiring external high-level bias for TPS2216A functionality. Standby mode reduces all output current limits to 50 mA (typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) xVCC (3.3 V) | 60 mΩ typical at TJ = 25°C, IO = 750 mA - ensures ≤45 mV drop at 750 mA for tight 3.3-V regulation |
| rDS(on) xVCC (5 V) | 140 mΩ typical at TJ = 25°C, IO = 750 mA - supports ≤105 mV drop at 750 mA within PCMCIA 5% regulation window |
| xVPP Switch rDS(on) | 0.7 Ω typical at TJ = 25°C, IO = 50 mA - enables stable 12-V programming voltage delivery to flash memory |
| Quiescent Current | 150 µA maximum - minimizes system standby power in battery-operated notebooks and PDAs |
| Standby Current Limit | 50 mA typical per output - reduces fault energy during sleep-mode card insertion/removal |
| Operating Temperature | −40°C to +70°C ambient - validated for industrial-grade embedded host platforms |
| Package | 30-pin SSOP (DB) - surface-mount compatible with standard PCB assembly, 0.65-mm pitch |
Pinout & Package
TPS2216ADB is housed in a 30-pin plastic small-outline package (SSOP-DB), 0.65-mm lead pitch, with exposed thermal pad not connected internally. Pin functions are defined for the DB-30 variant per SLVS267C Rev FEBRUARY 2008.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 30 | 5V Input | Primary 5-V supply rail for chip logic and card VCC distribution |
| 7, 24 | 12V Input | Input for 12-V Vpp programming voltage; both pins must be tied together |
| 9, 10, 11 | AVCC Output | First channel VCC output (3.3 V / 5 V / GND / Hi-Z) to Card A |
| 8 | AVPP Output | First channel VPP output (3.3 V / 5 V / 12 V / GND / Hi-Z) to Card A |

| 23 | BVPP Output | Second channel VPP output (3.3 V / 5 V / 12 V / GND / Hi-Z) to Card B |
| 29 | MODE Input | Must be externally pulled high for TPS2216A operation; internal 150-kΩ pulldown |
| 19 | STBY Input | Active-low standby enable; internal 150-kΩ pullup - asserts 50-mA current limit on all outputs |
| 18 | OC Output | Open-drain fault indicator low during overcurrent or thermal shutdown |
| 6, 14 | RESET Inputs | Two reset inputs: active-high (pin 6) and active-low (pin 14); each with internal bias resistor |
Key Features
| Feature | Design Value |
|---|---|
| Independent xVPP Programming | Enables separate voltage selection (3.3 V / 5 V / 12 V) for AVPP and BVPP without affecting xVCC states - critical for mixed-memory-card configurations |
| Break-Before-Make Switching | Prevents short-circuit transients during voltage rail transitions - eliminates cross-conduction risk between VCC/VPP domains |
| 3.3-V Low-Voltage Mode | Allows full 3.3-V xVCC switching when 5-V rail is absent - supports ultra-low-power sleep modes in portable systems |
| Internal Power-On Reset | Ensures deterministic initial state on power-up without external RC network - simplifies system-level reset sequencing |
| Serial Control Interface | Three-wire (CLOCK/DATA/LATCH) protocol enables compact GPIO usage and flexible configuration of both channels via software |

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 |
|---|---|---|---|
| TPS2216ADAP(R) | Identical functionality and pinout, but in thermally enhanced 32-pin TSSOP (DAP) package with PowerPAD™ | Higher power dissipation capability (4255 mW vs. 602 mW at TA = 70°C) - suited for high-ambient or continuous-load environments | Select TPS2216ADAP(R) when thermal margin is constrained and PCB layout allows larger footprint with exposed pad soldering. |
| TPS2214ADB(R) | Same DB package and pinout, but lacks independent xVPP programming - AVPP/BVPP share common control bits | Reduced flexibility for mixed-voltage card stacks; no 12-V VPP support on BVPP channel | Choose TPS2214ADB(R) only for cost-sensitive single-card designs where dual independent VPP control is unnecessary. |
Compared with TPS2216ADAP(R), the TPS2216ADB offers lower thermal performance but smaller board area; compared with TPS2214ADB(R), it delivers full dual-channel VPP independence essential for CableCARD™ and dual-modem deployments.

FAQ
What is the function of the MODE pin on the TPS2216ADB?
The MODE pin on the TPS2216ADB determines device operating mode: it must be externally pulled high to enable full TPS2216A functionality, including independent xVPP programming. When floating or pulled low, the device defaults to TPS2206-compatible behavior. The pin has an internal 150-kΩ pulldown resistor, so a deliberate high-level bias is required for correct TPS2216ADB operation.
Does the TPS2216ADB support 12-V VPP on both AVPP and BVPP outputs?
Yes, the TPS2216ADB supports 12-V VPP on both AVPP (pin 8) and BVPP (pin 23) outputs. Each xVPP channel can be independently programmed to 3.3 V, 5 V, or 12 V via the serial interface when MODE is high. The 12-V input is supplied through pins 7 and 24, which must be connected together per datasheet guidance.
What is the maximum continuous output current for xVCC channels on the TPS2216ADB?
The TPS2216ADB supports 750 mA continuous output current per xVCC channel (AVCC and BVCC) at TA = 70°C, as specified in recommended operating conditions. At 25°C ambient, the device can sustain higher currents limited only by thermal design; however, 750 mA is the guaranteed minimum across the full −40°C to +70°C operating range.
How does the STBY pin affect current limiting on the TPS2216ADB?
Asserting STBY low places the TPS2216ADB into standby mode, reducing all xVCC and xVPP output current limits to 50 mA (typical). This mode is intended for low-power card insertion/removal sequences and is activated by pulling STBY low - the pin has an internal 150-kΩ pullup resistor, so no external pullup is required.
Is the TPS2216ADB pin-compatible with earlier TPS2216 variants?
Yes, the TPS2216ADB is backward-compatible with the TPS2216 and forward-compatible with TPS2216ADBR (taped/reel version). All share identical 30-pin DB package pinout, electrical characteristics, and functional behavior - differing only in packaging format and reel specification, not silicon or pin assignment.
