The TPS22934YZVT is a single-channel, high-side P-channel load switch from Texas Instruments, specified for 1 A continuous output with a typical on-resistance of 63 mOhm. The load voltage range of 1.5 V to 3.6 V covers 1.8 V and 3.3 V logic rails common in portable, battery-powered, and embedded designs — the Rds(on) directly sets the voltage drop and thermal rise at full load. On/Off interface with non-inverting input simplifies enable logic; no external Vcc supply is required.
Industrial temp, slew rate, load discharge
Built-in slew rate control limits inrush current during turn-on, reducing supply droop on a shared rail. The load discharge feature pulls the output to ground when the switch is disabled, preventing floating output — critical for sequencing or when the downstream load is sensitive to indeterminate states. Fault protection includes undervoltage lockout (UVLO) on the input.
Active production, DSBGA-4 package
The part is ROHS3 compliant. Package is 4-XFBGA, DSBGA, supplier device package 4-DSBGA (0.88x0.88 mm). The ultra-small footprint (0.88 mm per side) suits space-constrained designs but demands a fine-pitch assembly process — confirm your PCB fab and pick-and-place capability for a 0.4 mm ball pitch.
