The Texas Instruments TPS22913CYZVR is a single-channel, high-side P-channel load switch in a 4-bump DSBGA package measuring 0.88 x 0.88 mm. It handles a load voltage from 1.4 V to 5.5 V and delivers up to 2 A continuous output. Typical Rds(on) is 60 mOhm, which keeps conduction losses low for a 2 A rail. The switch is controlled by a simple On/Off logic input (non-inverting) and does not require a separate Vcc supply — the gate drive is derived from the input voltage. It is suited for point-of-load power gating in portable devices, SSDs, set-top boxes, and other space-constrained electronics where a small footprint and low on-resistance matter.
Built-in fault protection includes reverse current blocking (prevents back-feed from output to input when the switch is off) and undervoltage lockout (UVLO) that holds the switch off until the input voltage is high enough for proper gate drive. The slew rate controlled turn-on limits inrush current into capacitive loads, and the load discharge feature pulls the output to ground when the switch is disabled — no floating rail, no surprise hold-up.
For volume production or dual-source planning, the base product number TPS22913 covers multiple package and tape options — confirm the exact suffix (CYZVR) for the DSBGA variant.
