TPS22811LRPWR

TPS22811LRPWR is TI’s single-channel high-side load switch used to power-gate a rail in low‑voltage/battery-powered systems. It sits between the supply and a load (e.g., MCU peripherals, sensors, memory) and is controlled by an EN pin for simple on/off sequencing.
Key features (typical):
- Low-voltage operation (Vin in the low‑voltage range, commonly 0.9–5.5 V)
- Enable control (logic-compatible EN input)
- Built‑in current limit, overcurrent protection
- Reverse-current blocking when off
- Thermal protection and fast/controlled turn‑on (soft-start)
- Low quiescent current for long battery life
- RoHS-compliant, in the LRPWR package variant (leadless power package)
Applications: power gating for microcontrollers, sensors, memory, displays, wearables, and other IoT/battery-powered devices.
Note: Exact electrical specs (on-resistance, current limit, EN thresholds) and packaging details are in the TPS22811 datasheet for the LRPWR variant.

TPS22811LRPWR is a TI 1-channel load switch with current limit and enable. For exact equivalents, please specify: (a) TI-to-TI cross-reference or cross-vendor, (b) input voltage range, (c) max load current, (d) required current limit, (e) packaging. With those details I’ll provide precise part numbers.

TPS22811LRPWR features (highlights):
- Single-channel high-side load switch with current-limit and short-circuit protection
- Enable input to turn the switch on/off
- Undervoltage lockout (UVLO) to prevent unwanted turn-on
- Reverse-current protection (output-to-input blocking)
- Slew-rate controlled turn-on (soft-start) to limit inrush
- Thermal/overtemperature protection
- Low quiescent current in both ON and OFF states (ideal for battery-powered apps)
- Very small, RoHS-compliant package (LRPWR) suitable for compact designs
Optional notes:
- Integrates protection and control suitable for portable electronics, power-management, and any system needing safe, efficient load switching.

- Pin count: 5 pins
- Function: A single-channel high-side load switch. It gates VIN to VOUT under control of the EN (enable) input; GND is ground; one pin is No Connect on this package variant. Used for power-gating downstream circuitry with built-in protection/current-limit features.

Manufacturer: Texas Instruments (TI).
What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits; one of the world’s largest semiconductor producers, headquartered in Dallas, Texas.

TPS22811LRPWR is a high-side load switch with protection used to gate power rails. Typical application areas:
- Power distribution and sequencing for portable/battery-powered devices
- Gating for CPUs/MCUs, memory, sensors, and RF modules
- Consumer electronics (phones, tablets, wearables, IoT)
- Automotive and industrial electronics needing soft-start and protection (overcurrent, reverse current)
- Hot-swapping of supply rails and USB/peripheral power switching
- Power-gating to reduce standby leakage and extend battery life
It provides enable control, protection, and controlled startup for reliable PMIC architectures.

TPS22811LRPWR comes in an 8-pin VSON package (2.9 × 3.0 mm), RoHS Pb-free.
