That means if a downstream short or overload pulls more than 500 mA, the switch limits the current and eventually shuts off if the die gets too hot. It also has a status flag output that goes low when a fault is active — useful for a microcontroller interrupt or a simple LED indicator. There is no reverse-current protection, so if the load side goes above the input, current can flow backward through the body diode. ## Supply and logic — no Vcc needed The switch is self-powered from the load voltage rail (2.7 V to 5.5 V) — there is no separate Vcc pin. The enable inputs are non-inverting and work with standard logic levels. Because the input type is non-inverting, a logic high turns the corresponding output on. The ratio of inputs to outputs is configurable: one input drives two outputs (1:2) and the other input drives the third output (1:1), giving you independent control of a dual-load channel and a single-load channel. ## Temperature range and environment Rated for junction temperature from -40°C to 125°C, this part handles industrial and automotive cabin environments without issue. It is surface-mount in a standard 16-SOIC footprint, so rework with a hot-air station is straightforward — no lab bench required. The package is 3.90 mm wide, which is the narrow SOIC width, so check your PCB footprint if you are swapping from a wider body. ## Lifecycle and sourcing The TPS2053BDR is listed as Active with ROHS3 compliance. It is a current-production part from Texas Instruments, so there is no end-of-life pressure for new designs. If you need a dual-sourcing option, TI also makes the TPS2053BDR in the same package, but there is no pin-compatible second source from another manufacturer listed in the records.","metaTitle":"TPS2053BDR power switch, 3-ch high-side, 500mA, 70mOhm","metaDescription":"TI TPS2053BDR 3-channel high-side power switch, 500mA per output, 70mOhm Rds(on), 2.7-5.5V input, -40 to 125°C.
