The Texas Instruments TPS2226DBR is a dual-slot CardBus power-interface switch designed for integrated power management solutions in systems with PC Card sockets. It offers controlled distribution of 3.3 V, 5 V, and 12 V to each card slot, eliminating the need for external fuses due to its built-in current-limiting and thermal-protection features.
Key electrical specifications include a 1A current rating, 95mOhm typical Rds(on), and TTL-compatible logic inputs. The device supports independent VPP/VCC switching and features break-before-make switching for reliable operation. It operates within a temperature range of -40°C to 85°C.
Packaged in a 30-pin SSOP, the TPS2226DBR is suitable for surface mounting. Its applications include notebook and desktop computers, bar code scanners, digital cameras, set-top boxes, and PDAs, providing essential power control for peripheral devices.
The device also includes features like status flag reporting for fault isolation and power-on reset functionality. The quiescent current is typically 140µA from a 3.3-V input.
