It integrates three output channels, each capable of delivering up to 500 mA continuously, with a typical on-resistance of 70 mOhm per channel to minimize voltage drop and power dissipation. The input-to-output ratio is configurable as 1:2 or 1:1, meaning the three outputs can be driven from one or two enable signals, giving flexibility in how the switch banks are ganged together. ## Fault protection and status reporting for robust system design Built-in fault protection includes fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO), so the switch handles overcurrent and thermal events without external sense resistors or supervisory circuits. A status flag output (open-drain, active low) asserts when a fault condition is detected — overcurrent, overtemperature, or UVLO — allowing a host microcontroller to log the event or retry the power cycle.","metaTitle":"TPS2043BD Texas Instruments Power Switch, 3 Outputs, 500mA","metaDescription":"TPS2043BD high-side power switch from TI, 3 outputs at 500mA each, 70mOhm Rds(on), active production, ROHS3 compliant.
