概要
Description
TPS2064CDGNR is Texas Instruments’ single-channel high-side load switch with built‑in protection. It sits between a system supply (Vin) and a downstream load, enabling or gating power under digital control. Key ideas:
- Integrated MOSFET with low on-resistance, suitable for dropping in to power rails with minimal voltage drop.
- Protection features: overcurrent/short-circuit protection, undervoltage lockout (UVLO), thermal shutdown, and reverse-current protection.
- Control: EN input to turn the switch on/off; designed for simple power‑up sequencing and controlled turn‑on (soft-start behavior helps limit inrush).
- Operating range: intended for typical 1.8–5.5 V systems often used in battery-powered devices (check datasheet for exact limits).
- Package: CDGNR denotes TI’s specific package and reel/packaging variant.
Common uses: gate regulators, sensors, microcontrollers, or other loads that benefit from a protected, controlled power switch.
Note: For exact electrical specs, pinout, and timing details, refer to the TPS2064 datasheet and the CDGNR packaging notes.
