The TPS2228DBR is a versatile and robust power management integrated circuit (IC) designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This IC is particularly suitable for applications requiring dual-slot PC Card power interface switches. It is engineered to handle the power distribution requirements of two PC Cards, supporting both 3.3V and 5V operations.
One of the key features of the TPS2228DBR is its ability to provide short-circuit and thermal protection, ensuring the safety and reliability of the connected devices. It is equipped with an under-voltage lockout (UVLO) feature that prevents operation at low input voltages, which could be harmful to the system.
Key Specifications:
- Part Number: TPS2228DBR
- Manufacturer: Texas Instruments
- Package/Case: SSOP-30 (Shrink Small Outline Package)
