Features
The TPS2065CDBVR is a power distribution switch designed by Texas Instruments. It features a single N-channel MOSFET with a low on-resistance, allowing it to handle a continuous load current of up to 1.5A. The device operates over an input voltage range of 4.5V to 5.5V, making it suitable for USB and other 5V applications. It includes built-in current limiting and thermal protection to prevent damage from overcurrent conditions and excessive temperatures. The switch supports reverse current blocking, ensuring no current flows from the output back to the input when disabled. It also features an under-voltage lockout (UVLO) to ensure the switch remains off until the input voltage is sufficient for reliable operation. The enable pin allows for easy on/off control. Additionally, the TPS2065CDBVR is housed in a small SOT-23 package, making it ideal for space-constrained applications. Its robust design and protection features make it suitable for use in various consumer electronics and industrial applications.
