Description and Introduction

1A Dual-Slot PC Card Power Switch w/ Parallel Interface The TPS2201IDBR is a power-distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 500mA  
- **On-Resistance (RDS(ON)):** 95mΩ (typical) at 5V  
- **Quiescent Current:** 35µA (typical)  
- **Shutdown Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP (DBR), 20-pin  

### **Descriptions:**  
The TPS2201IDBR is a single-channel power-distribution switch designed for applications requiring controlled power management. It provides overcurrent protection, thermal shutdown, and controlled rise time to minimize inrush current.  

### **Features:**  
- Adjustable current limit (500mA typical)  
- Thermal shutdown protection  
- Fast short-circuit response  
- Controlled rise time to reduce inrush current  
- Low quiescent current in shutdown mode  
- Reverse current blocking  
- Under-voltage lockout (UVLO)  

This information is based on TI's official documentation for the TPS2201IDBR.

Application Scenarios & Design Considerations

1A Dual-Slot PC Card Power Switch w/ Parallel Interface

Alternative Part Number

  • MIC2505-2YM --: Single high-side power switch with current limiting and thermal shutdown, functionally similar to the TPS2201 power distribution switch and available in a comparable SOIC package.
  • AAT4610AIGV-T1 --: Current-limited high-side load switch with enable and fault flag, suitable replacement for power distribution switching in the same voltage range.
  • AP2553W6-7 --: Adjustable current-limited power switch with thermal protection, offering similar load-switch functionality in a small package.
