Product details
Overview
TPS2212IDBR from Texas Instruments is a single-slot, parallel-interface power switch IC designed for low-power PC Card (PCMCIA) sockets. It integrates dual VCC and VPP switching paths with 160-mΩ rDS(on) at 5 V, 450-mA typical current limit on VCC, 3.3-V low-voltage mode operation, and break-before-make sequencing - enabling compliant power delivery to 3.3-V/5-V/12-V PC Cards in PDAs, barcode scanners, and compact flash interfaces.
For engineers reviewing the TPS2212IDBR datasheet, TPS2212IDBR pinout, TPS2212IDBR application, or TPS2212IDBR equivalent, key selection criteria include its integrated overcurrent reporting (OC pin), thermal protection, shutdown-controlled high-impedance outputs, and compatibility with PCMCIA 3.3-V/5-V transition protocols - all in a space-saving 16-pin SSOP (DB) package.
Technical Context
The TPS2212IDBR implements a LinBiCMOS-based parallel-control architecture with independent VCC and VPP switching matrices, each governed by two logic inputs (VCCD0/VCCD1 and VPPD0/VPPD1) and coordinated by internal break-before-make logic. Its 3.3-V low-voltage mode eliminates dependency on 5-V bias when only 3.3 V is available - critical for sleep-mode and pager-mode systems.
Current limiting is implemented via sense-FETs per output (not external resistors), delivering 450 mA typ on VCC and 280 mA typ on VPP without added series resistance. Overcurrent detection drives the open-drain OC pin low, while thermal shutdown disables outputs until junction temperature falls below threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC rDS(on) | 160 mΩ typ at 5 V - enables ≤250 mA continuous delivery within PCMCIA 5% voltage regulation (≤100 mV drop). |
| VPP rDS(on) | 1 Ω typ at 12 V - supports 150 mA continuous VPP output for flash programming without external boost circuitry. |
| VCC Current Limit | 450 mA typ - protects host power rails and PCB traces during hot-insertion of faulty cards. |
| VPP Current Limit | 280 mA typ - provides safe 12-V programming current while avoiding latch-up under short-circuit conditions. |
| Operating Temp Range | –40°C to +85°C - validated for industrial and portable embedded environments including notebook computers and PDAs. |
| Shutdown Quiescent Current | 1 µA max - ensures minimal battery drain during system sleep or software-initiated shutdown. |
| Package | 16-pin SSOP (DB), 0.65-mm pitch - surface-mount compatible with standard reflow profiles; R-suffix denotes tape-and-reel packaging. |
Pinout & Package
TPS2212IDBR is housed in a 16-pin Small Outline Package (SSOP-DB), measuring 4.9 mm × 6.0 mm × 1.75 mm, with 0.65-mm lead pitch and exposed pad not present. The package is rated for –40°C to +85°C ambient operation and supports standard FR4 board mounting without special thermal pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCD0 (Pin 1) | VCC voltage select input | Controls VCC output level (0 V / 3.3 V / 5 V) per PCMCIA control logic table; logic-compatible with 3.3-V or 5-V drive. |
| VCCD1 (Pin 2) | VCC voltage select input | Second bit of 2-bit VCC control code; enables break-before-make transitions between voltage states. |
| 3.3V (Pins 3,4) | 3.3-V input supply | Provides power for chip bias and/or card VCC when 5 V is absent; supports 3.3-V-only low-power modes. |
| 5V (Pins 5,6) | 5-V input supply | Primary bias source for internal charge pump and gate drivers; also supplies VCC output when selected. |
| GND (Pin 7) | Power ground | Common return for all internal circuits and output switches; must be low-impedance connection to system ground plane. |
| OC (Pin 8) | Overcurrent indicator | Open-drain logic-low signal asserted during VCC or VPP overcurrent; used for fault diagnostics and system-level error reporting. |
| SHDN (Pin 16) | Global shutdown enable | Active-low input that forces all VCC/VPP outputs into high-impedance state; reduces quiescent current to ≤1 µA. |
| VPPD0 (Pin 15) | VPP voltage select input | First bit of 2-bit VPP control code; selects 0 V / 3.3 V / 5 V / VPPI (12 V) output per PCMCIA specification. |
| VPPD1 (Pin 14) | VPP voltage select input | Second bit of 2-bit VPP control code; coordinates with VPPD0 to implement PCMCIA-compliant VPP sequencing. |
| VCC (Pins 11,12,13) | Switched VCC output | Three paralleled pins deliver regulated 0 V / 3.3 V / 5 V to PC Card; paralleling minimizes trace resistance and voltage drop. |
| VPP (Pin 10) | Switched VPP output | Single-pin 12-V-capable output for flash memory programming; internally clamped to ≤0.8 V during short-circuit events. |
| VPPI (Pin 9) | Main VPP input | Accepts 3.3 V–12 V input for VPP switching; allows disabling of external 12-V rail except during flash operations. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated VCC + VPP switching | Eliminates ≥8 discrete MOSFETs, gate drivers, and current-sense resistors - reducing BOM count and PCB area in PC Card socket designs. |
| Break-before-make logic | Prevents voltage contention during VCC/VPP transitions (e.g., 5 V → 3.3 V), satisfying PCMCIA 3.3-V/5-V switching requirements. |
| 3.3-V low-voltage mode | Enables full functionality using only 3.3-V input - essential for battery-powered sleep/pager modes where 5-V rail is disabled. |
| On-chip overcurrent reporting | OC pin provides real-time fault indication without external comparators or microcontroller polling - accelerating system diagnostics. |
| Thermal shutdown protection | Automatically disables outputs if junction temperature exceeds 150°C - preventing permanent damage during sustained overload or poor heatsinking. |

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 |
|---|---|---|---|
| TPS2211IDBR | Higher VCC current limit (1 A typ vs. 450 mA); no 3.3-V-only mode - requires 5-V bias for operation. | Suitable for higher-power PC Card applications (e.g., hard-disk adapters), but incompatible with 3.3-V-only sleep modes. | Select TPS2211IDBR only when ≥1-A VCC delivery is required and 5-V bias is always available. |
| MAX1968EAP+ | Single-channel 3.3-V/5-V switch (no VPP path); 120-mΩ rDS(on); no OC pin or thermal shutdown. | Limited to basic VCC switching in non-PCMCIA-compliant or low-complexity add-on cards lacking flash programming needs. | Choose MAX1968EAP+ only for cost-sensitive, single-rail designs where VPP support and fault reporting are unnecessary. |
Compared with TPS2212IDBR, TPS2211IDBR offers higher current capacity but sacrifices 3.3-V-only operation, while MAX1968EAP+ reduces integration by omitting VPP switching and protection features - making TPS2212IDBR the only option supporting full PCMCIA-compliant dual-rail, low-voltage, and fault-reporting requirements.

FAQ
What is the primary function of the TPS2212IDBR in a PC Card system?
The TPS2212IDBR serves as a fully integrated parallel-interface power switch for single-slot PC Card (PCMCIA) sockets. It manages dual-rail power delivery - switching 3.3-V, 5-V, and 12-V voltages to the card's VCC and VPP terminals - while enforcing break-before-make sequencing, current limiting, thermal protection, and overcurrent reporting. Its design eliminates discrete MOSFETs, drivers, and fuses, reducing BOM count and improving reliability in portable and embedded hosts.
Does the TPS2212IDBR support 3.3-V-only operation without a 5-V supply?
Yes, the TPS2212IDBR supports true 3.3-V low-voltage mode: when VI(5V) = 0 V, it derives bias power from the 3.3-V input pins (3,4) and delivers only 3.3-V to the card's VCC terminal. This capability is explicitly validated in the datasheet and enables compliance with sleep-mode and pager-mode power constraints where 5-V rails are disabled - a feature not present in the pin-compatible TPS2211IDBR.
How does the OC (overcurrent) pin function on the TPS2212IDBR?
The OC pin on the TPS2212IDBR is an open-drain output that pulls low when either the VCC or VPP output enters overcurrent condition - defined as exceeding 300–600 mA (VCC) or 120–400 mA (VPP). It remains asserted until the fault clears and the device recovers, providing immediate hardware-level fault signaling to the host controller. This eliminates need for software polling or external current-sense amplifiers, enabling faster diagnostics in systems like barcode scanners and PDAs.
What is the maximum continuous output current supported by the TPS2212IDBR on VCC and VPP rails?
The TPS2212IDBR delivers 250 mA continuous on VCC and 150 mA continuous on VPP while maintaining PCMCIA voltage regulation limits (≤100 mV drop at 250 mA for 5-V VCC; ≤200 mV at 250 mA for 3.3-V VCC; ≤100 mV at 150 mA for 12-V VPP). These values are specified across –40°C to +85°C and reflect actual usable current under regulation - not just short-circuit limits - ensuring reliable operation in notebook computers and industrial I/O modules.
Can the TPS2212IDBR be used in new designs given its 2001 datasheet revision date?
Yes, the TPS2212IDBR remains actively manufactured and stocked by Texas Instruments and major distributors (Digi-Key, Mouser). Its DB package (SSOP-16) and electrical specifications are unchanged since release, and it continues to meet PCMCIA standards for legacy and retrofit PC Card socket designs. TI's Product Change Notifications confirm no obsolescence plans, and Aetrix Electronics guarantees long-term availability with full traceability and lifecycle coordination for production programs.
