Texas Instruments Integrated Circuits (ICs) - Power Management (PMIC) - Power Distribution Switches, Load Drivers TPS2202IDFR

The TPS2202IDFR is a dual-slot PC Card power-interface switch designed for use with serial PCMCIA controllers. It integrates all necessary components, including discrete power MOSFETs, a logic section, current limiting, thermal protection, and power-good reporting into a single package, which simplifies design and reduces component count. The device supports 3-V, 5-V, and 12-V power distribution, making it versatile for various applications. This switch features an internal charge pump that allows the 12-V supply to be disabled except during flash programming, thereby enhancing battery life. It operates with a low quiescent current of 1 µA and a typical supply current of 83 µA, contributing to power efficiency. The TPS2202IDFR also includes short-circuit and thermal protection, ensuring reliable operation under varying conditions. It is housed in a space-saving 30-pin SSOP package and meets PCMCIA standards, making it suitable for applications in notebook computers, PDAs, digital cameras, and other portable devices.
