Dual-Slot Cardbus Power-Interface Switches for Serial PCMCIA Controllers The TPS2223A is a power-distribution switch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:
### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V
- **Continuous Current Limit:** 1.5A (typical)
- **On-Resistance (RDS(ON)):** 80mΩ (typical at 5V)
- **Overcurrent Protection:** Adjustable (factory-set or resistor-programmable)
- **Thermal Shutdown Protection:** Yes
- **Operating Temperature Range:** -40°C to +85°C
- **Package Type:** 8-Pin SOIC (D)
### **Descriptions:**
- The TPS2223A is a single-channel, low-side power-distribution switch designed for hot-swap and power-rail management applications.
- It provides controlled turn-on to limit inrush current and protects circuits from overcurrent and overtemperature conditions.
- Suitable for USB power switching, portable devices, and other low-voltage power distribution systems.
### **Features:**
- **Adjustable Current Limit:** Can be set via an external resistor.
- **Fast Overcurrent Response:** Shuts off within microseconds in case of a fault.
- **Reverse Current Blocking:** Prevents backflow when the output voltage exceeds the input.
- **Controlled Turn-On:** Reduces inrush current with a built-in slew-rate control.
- **Low Quiescent Current:** Optimized for battery-powered applications.
- **Undervoltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.
