Product details
Overview
TPS2216ADAPG4 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 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 digital cameras.
For engineers reviewing the TPS2216ADAPG4 datasheet, TPS2216ADAPG4 pinout, TPS2216ADAPG4 application, or TPS2216ADAPG4 equivalent, key selection criteria include its dual-output programmable VCC/VPP architecture, 30-pin SSOP (DB) and 32-pin TSSOP (DAP) package options, standby-mode 50-mA current limit, 150-µA max quiescent current, and compatibility with PC Card™ standards for legacy embedded host systems.
Technical Context
The TPS2216ADAPG4 implements two independent high-side power switches per channel - one for xVCC (3.3 V or 5 V) and one for xVPP (3.3 V, 5 V, or 12 V) - controlled via serial interface (CLOCK/DATA/LATCH) or direct logic inputs. Its MODE pin configures operation between TPS2206 legacy mode (floating/low) and native TPS2216A mode (externally pulled high), enabling backward compatibility while supporting independent xVPP programming.
Internal current limiting (750 mA xVCC / 200 mA xVPP at TA = 70°C), thermal shutdown (trip at 155°C), and OC fault reporting provide system-level protection without external fuses. The device supports 3.3-V low-voltage mode - allowing full xVCC switching when only 3.3 V is available - and features internal power-on reset plus pullup/pulldown resistors on RESET, STBY, and MODE pins for deterministic startup behavior.

| 24 | BVPP output | Second xVPP output channel, fully independent of BVCC and AVPP - required for simultaneous S-CARD/M-CARD support. |
| 19 | STBY input | Active-low logic input that forces all outputs into 50-mA current-limited standby mode - essential for safe hot-plug sequencing. |
| 20 | OC output | Open-drain fault indicator active low during overcurrent or overtemperature events - enables system-level fault isolation and recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Independent xVPP programming | Enables separate voltage assignment for each xVPP output (e.g., AVPP = 12 V, BVPP = 5 V), satisfying asymmetric flash programming requirements across dual cards. |
| 3.3-V low-voltage mode | Allows full xVCC switching using only 3.3-V supply - eliminates need for 5-V rail during system sleep, reducing BOM count and power conversion losses. |
| Break-before-make switching | Prevents momentary shorting between VCC/VPP rails during voltage transitions - mandatory for safe hot-swap compliance in PC Card systems. |
| Integrated thermal protection | Shuts down outputs at 155°C junction temperature with 10°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Serial control interface | CLOCK/DATA/LATCH pins enable compact microcontroller-based configuration without dedicated GPIO expansion - reduces host MCU pin count and firmware complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2216ADB | 24-pin SSOP (DB) package; lower thermal performance (602 mW @ TA = 70°C vs. 2340 mW for DAP); identical electrical specs. | Suitable for cost-sensitive, lower-power dual-card hosts where PCB space allows larger SSOP footprint and thermal margin is adequate. | Select TPS2216ADB only if board layout constraints favor SSOP and peak power dissipation remains below 600 mW. |
| TPS2214A | Single-channel variant (one AVCC/AVPP pair only); lacks BVCC/BVPP outputs and some serial control bits; same pinout subset in DB package. | Applicable only for single-PC-Card systems; cannot replace TPS2216ADAPG4 in dual-card configurations without hardware redesign. | Choose TPS2214A only for new single-slot designs - not a drop-in replacement for TPS2216ADAPG4 due to missing second channel. |
Compared with TPS2216ADB and TPS2214A, the TPS2216ADAPG4 delivers superior thermal handling (3.9× higher power rating than DB variant) and full dual-card functionality, making it the sole option for compact, high-reliability portable systems requiring simultaneous S-CARD/M-CARD support under thermal stress.

FAQ
What is the function of the MODE pin on the TPS2216ADAPG4?
The MODE pin on the TPS2216ADAPG4 selects operational mode: when pulled high externally (≥2 V), it enables native TPS2216A functionality including full serial interface control and independent xVPP programming; when floating or pulled low, it defaults to TPS2206-compatible mode with reduced feature set. The pin has an internal 150-kΩ pulldown resistor, so a deliberate external pullup is required for TPS2216A operation. This ensures backward compatibility while preserving advanced capabilities in new designs using the TPS2216ADAPG4.
Does the TPS2216ADAPG4 support 3.3-V-only operation without a 5-V supply?
Yes, the TPS2216ADAPG4 supports true 3.3-V-only operation via its dedicated 3.3-V low-voltage mode. When only the 3.3-V input is powered (and 5-V input is at 0 V), the device can still drive both AVCC and BVCC outputs at 3.3 V with full current capability (750 mA) and protection features enabled. This mode eliminates dependency on a 5-V rail during system sleep or low-power states, directly reducing power conversion overhead. The TPS2216ADAPG4 maintains full functionality - including OC reporting and STBY mode - under this condition, as confirmed in the SLVS267C datasheet Section 1.
How does the TPS2216ADAPG4 implement overcurrent protection?
The TPS2216ADAPG4 implements per-output overcurrent protection with fast response: for xVCC switches, current limiting activates within 100 µs during a short (tested at 100-mΩ load), clamping output current to 750 mA (typical) at TA = 70°C; for xVPP, response is 16 µs with 200 mA limit. An open-drain OC pin asserts low during fault conditions, enabling host MCU interrupt-driven recovery. Unlike fuse-based solutions, this protection is fully resettable - outputs resume normal operation automatically after fault removal and thermal recovery. These characteristics are measured and specified in the SLVS267C datasheet Electrical Characteristics tables.
What is the purpose of the STBY pin on the TPS2216ADAPG4?
The STBY pin on the TPS2216ADAPG4 is an active-low logic input that forces all xVCC and xVPP outputs into a 50-mA current-limited standby state when asserted. This mode reduces fault energy during hot-plug events, protects against inrush currents when cards are inserted, and minimizes power loss in idle systems. The pin has an internal 150-kΩ pullup resistor, ensuring safe default operation (outputs enabled) when left unconnected. In the TPS2216ADAPG4, STBY assertion also disables internal clock circuitry to further reduce quiescent current - a critical feature for battery-operated devices relying on the TPS2216ADAPG4 for power sequencing.
Can the TPS2216ADAPG4 drive both 3.3-V and 12-V outputs simultaneously?
Yes, the TPS2216ADAPG4 can drive 3.3-V and 12-V outputs simultaneously: AVCC and BVCC can be configured for 3.3 V (or 5 V), while AVPP and BVPP can be independently set to 12 V - satisfying the PC Card requirement for separate VCC (logic power) and VPP (programming voltage) rails. This is achieved via the serial interface (CLOCK/DATA/LATCH) or direct logic control, with no conflict between channels. The device's absolute maximum ratings confirm 14-V tolerance on xVPP pins, and recommended operating conditions specify VI(12V) up to 13.5 V. All combinations are validated in the SLVS267C datasheet Functional Block Diagram and Terminal Functions table.
