Description and Introduction

Dual-Slot Cardbus Power-Interface Switches for Serial PCMCIA Controllers The TPS2226ADB is a power-distribution switch manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Part Number:** TPS2226ADB  
- **Type:** Dual-channel power-distribution switch  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current per Channel:** 1.5A  
- **On-Resistance (RDS(ON)):** 80mΩ (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-20 (DB)  

### **Descriptions:**
- The TPS2226ADB is a dual-channel power-distribution switch designed for applications requiring multiple power rails.  
- It provides controlled power switching with protection features such as overcurrent and thermal shutdown.  
- Suitable for USB power management, hot-swap applications, and portable devices.  

### **Features:**
- **Dual Independent Channels:** Allows control of two separate power paths.  
- **Low On-Resistance:** Minimizes voltage drop and power loss.  
- **Overcurrent Protection:** Limits current to prevent damage.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Fast Turn-Off Response:** Quickly disconnects the load in fault conditions.  
- **Controlled Rise Time:** Reduces inrush current during power-up.  

For detailed electrical characteristics and application circuits, refer to the official Texas Instruments datasheet.

Application Scenarios & Design Considerations

Dual-Slot Cardbus Power-Interface Switches for Serial PCMCIA Controllers

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with current limiting, functionally similar to the TPS2226 dual power distribution switch and available in a comparable package.
  • AAT4616AIGU-1-T1 --: Current-limited high-side load switch suitable as a power distribution replacement, with adjustable current limit and thermal protection.
  • AP2552W6-7 --: Single-channel current-limited power switch offering similar protection features; can replace the TPS2226 in lower-channel-count designs.
  • TPS2226APW --: Same TPS2226A family device in a TSSOP package instead of SSOP, with identical dual-slot power switch functionality and pin-compatible logic.
  • MIC2536-2YM --: Dual-channel current-limited USB power switch with similar enable and fault-report features, suitable as a functional replacement in power distribution designs.
