TPS2216ADBR

Power Distribution Switches, Load Drivers Overview

The TPS2216ADBR is a dual-slot PC Card power-interface switch designed for serial PCMCIA controllers. It integrates three independent high-side switches to manage 3.3V, 5V, and 12V rails required by PC Card and CardBus standards. The device features a serial interface for control, allowing precise sequencing of power rails. It includes fixed current limiting and thermal shutdown protection to safeguard connected peripherals. Packaged in a 30-pin SSOP, it operates within a temperature range of -40°C to 70°C or 85°C depending on the specific suffix variant.
