Description
TPS2069CDGNR is a Texas Instruments single-channel high-side load switch (from the TPS206x family). It provides protected, controlled power to a downstream load, featuring current-limited switching, overcurrent and thermal protection, an enable input to turn the rail on/off, and a fault/status output. It operates from a single-supply rail suitable for common low-voltage systems and is designed for low quiescent current. The CDGNR suffix denotes a RoHS-compliant package type with tape-and-reel delivery. Typical uses include power gating for processors, memory, sensors, and LEDs, offering safe on/off control and protection without an external controller IC.
Equivalent
TPS2069CDGNR is TI’s 1-A high-side switch with current limit and fault protection. Exact equivalents depend on your specs and packaging. Please share: supply voltage, current limit, enable/diagnostic features, and whether you want TI-only substitutes or cross-vendor parts. With those, I can provide precise cross-references.
