Product details
Overview
TPS2216DAP from Texas Instruments is a dual-channel PC Card power-interface switch IC designed for notebook and desktop computers, PDAs, and digital cameras. It integrates two independent xVCC/xVPP switching channels (AVCC/AVPP and BVCC/BVPP), supports 3.3-V/5-V/12-V input rails, delivers ≤1 A per xVCC channel and 200 mA per xVPP channel, features 60-mΩ typical rDS(on) at 25°C for 3.3-V/5-V xVCC paths, and provides short-circuit and thermal protection.
For engineers reviewing the TPS2216DAP datasheet, TPS2216DAP pinout, TPS2216DAP application, or TPS2216DAP equivalent, key selection criteria include its dual-card power management capability, break-before-make switching, 3.3-V low-voltage mode operation without 5-V bias, independent xVPP programming, and compliance with PC Card™ standards for hot-swap-safe power delivery.
Technical Context
The TPS2216DAP implements two fully independent high-side power switches per channel - one for VCC (3.3 V/5 V) and one for VPP (3.3 V/5 V/12 V) - each with internal current limiting, thermal shutdown (trip at 155°C), and overcurrent detection reported via open-drain OC output. Its serial control interface (CLOCK/DATA/LATCH) enables programmable output configuration, including voltage selection and enable/disable sequencing.
It operates in three distinct modes: normal (full-current), standby (50-mA current limit per output), and 3.3-V-only low-voltage mode (enabling operation when only 3.3 V is available). The MODE pin must be externally pulled high for TPS2216 functionality, distinguishing it from backward-compatible TPS2206 behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) xVCC (3.3 V/5 V) | 60 mΩ typical at TJ = 25°C, enabling ≤100 mV drop at 1.67 A - meets PCMCIA 5% regulation for 5-V outputs. |
| rDS(on) xVPP (12 V) | 0.7 Ω typical at TJ = 25°C, supporting ≤200 mA continuous output with <150 mV drop - sufficient for flash programming. |
| Output current limit (xVCC) | 1 A typical at TA = 70°C; short-circuit limit drops to 35–65 mA in STBY mode - eliminates need for external fuses. |
| Quiescent current | ≤150 µA max in normal operation - critical for battery-powered sleep-mode retention. |
| Thermal shutdown | 155°C trip point with 10°C hysteresis - protects against sustained overload or poor heatsinking in compact enclosures. |
| Logic compatibility | TTL-level inputs (VIH ≥ 2 V, VIL ≤ 0.8 V); OC output drives low on fault - interfaces directly with standard microcontrollers. |
| Operating temperature | −40°C to +125°C virtual junction range - qualified for industrial and extended-temperature computing environments. |
Pinout & Package
TPS2216DAP is housed in a 32-pin PowerPAD™ Plastic Small Outline (DAP) package with exposed thermal pad for enhanced heat dissipation (4255 mW power rating at TA ≤ 25°C). The DAP package improves thermal performance over the 30-pin DB variant by >3×.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 32 | 5V | Input rail for 5-V card power and internal logic; must be biased for xVCC switching functionality. |
| 8, 25 | 12V | Input rail for 12-V VPP programming voltage; tied internally to both xVPP switches. |
| 10, 11, 12 | AVCC | Output: 3.3-V/5-V/GND/Hi-Z to Card A - controlled via serial interface and MODE state. |
| 9 | AVPP | Output: 3.3-V/5-V/12-V/GND/Hi-Z to Card A - independently programmable from AVCC. |
| 21, 22, 23 | BVCC | Output: 3.3-V/5-V/GND/Hi-Z to Card B - mirror function of AVCC with separate control. |
| 24 | BVPP | Output: 3.3-V/5-V/12-V/GND/Hi-Z to Card B - mirror function of AVPP with independent programming. |
| 19 | STBY | Active-low input that reduces all output current limits to 50 mA - enables low-power diagnostic or safe insertion mode. |
| 20 | OC | Open-drain fault indicator - pulls low during overcurrent or overtemperature events; requires external pullup. |
| 30 | MODE | Must be externally pulled high for TPS2216 operation; floating or low configures device as TPS2206-compatible mode. |
| 13 | GND | Power ground reference; connects to exposed PowerPAD for thermal and electrical return path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent xVCC/xVPP channels | Enables simultaneous, isolated power delivery to two PC Cards with separate voltage and enable control - no cross-talk or shared fault propagation. |
| Break-before-make switching | Prevents momentary shorting between VCC/VPP rails during voltage transitions - essential for safe hot-plug operation per PC Card standard. |
| 3.3-V low-voltage mode | Allows full xVCC switching using only 3.3-V input (no 5-V required), reducing system standby power and simplifying auxiliary rail design. |
| Internal power-on reset | Ensures defined initial state on power-up - prevents spurious outputs or undefined switching before firmware initialization. |
| Serial configuration interface | CLOCK/DATA/LATCH pins support 11-bit (MODE = high) or 9-bit (MODE = low) command words - enables flexible field-programmable output mapping. |

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 |
|---|---|---|---|
| TPS2216DB(R) | Identical electrical specs and functionality, but in 30-pin SSOP (DB) package without PowerPAD; 1095 mW max power rating vs. 4255 mW for DAP. | Lower thermal performance limits use in high-ambient or high-duty-cycle applications; unsuitable where PCB space permits DAP's superior heatsinking. | Select TPS2216DB(R) only when legacy SSOP footprint compatibility is required and thermal margin is verified. |
| TPS2206DB | Legacy predecessor with identical pinout but lacks 3.3-V low-voltage mode and independent xVPP programming; MODE pin pulls low internally. | Cannot operate without 5-V bias; no support for modern low-power sleep states or flexible VPP assignment - violates newer PC Card revision requirements. | Choose TPS2206DB only for cost-sensitive, non-sleep-capable designs where firmware cannot support TPS2216's extended feature set. |
Compared with TPS2216DB(R), the TPS2216DAP offers >3× higher power dissipation capability and lower thermal resistance, making it suitable for thermally constrained notebooks; versus TPS2206DB, it adds mandatory low-voltage mode and programmable VPP - essential for compliance with post-1999 PC Card specifications.

FAQ
What is the maximum continuous output current supported by the TPS2216DAP on its xVCC channels?
The TPS2216DAP supports up to 1 A continuous output current per xVCC channel (AVCC and BVCC) at TA = 70°C, as specified in the recommended operating conditions. This rating assumes proper PCB thermal design and is validated across the −40°C to +125°C junction temperature range. At elevated temperatures or with reduced airflow, derating applies per the dissipation rating table.
Does the TPS2216DAP require an external 5-V supply to operate in 3.3-V low-voltage mode?
No, the TPS2216DAP does not require an external 5-V supply to operate in 3.3-V low-voltage mode. When only the 3.3-V input (pins 16–18) is active and MODE is pulled high, the device enables full xVCC switching functionality using only the 3.3-V rail - a key feature for battery-powered sleep-state operation.
How does the OC (Overcurrent) pin on the TPS2216DAP behave during a thermal shutdown event?
The OC pin on the TPS2216DAP asserts low (active) during both overcurrent and overtemperature conditions, as stated in the electrical characteristics table. Thermal shutdown occurs at TJ = 155°C with 10°C hysteresis, and the OC signal remains low until the junction cools below 145°C and the fault condition is cleared - enabling unified fault handling in host firmware.
Can the TPS2216DAP independently control VPP voltage selection for each card slot?
Yes, the TPS2216DAP supports independent xVPP voltage selection for Card A (AVPP) and Card B (BVPP) via its serial interface. When MODE = high, an 11-bit command word allows separate configuration of AVPP and BVPP outputs to 3.3 V, 5 V, 12 V, GND, or Hi-Z - enabling mixed-voltage card operation without hardware modification.
What is the purpose of the MODE pin on the TPS2216DAP, and how should it be configured?
The MODE pin on the TPS2216DAP selects operational mode: it must be externally pulled high (≥2 V) to enable full TPS2216 functionality, including 3.3-V low-voltage mode and independent xVPP programming. If left floating or pulled low, the device defaults to TPS2206-compatible behavior - a backward-compatibility feature confirmed in the datasheet's Terminal Functions table.
