TPS22995RZGR

TPS22995RZGR thumbnail
Power Switch/Driver 1:1 N-Channel 3.8A 6-WQFN-HR (1.5x0.75)
The TPS22995RZGR is a high-current, low ON-resistance load switch designed for power distribution and power sequencing applications. It features an integrated N-channel MOSFET capable of handling high load currents while maintaining minimal voltage drop. The device includes controlled rise time to reduce inrush current, making it suitable for sensitive power rails and battery-powered systems. It also integrates thermal shutdown and overcurrent protection, ensuring safe operation under fault conditions. Its compact package and low quiescent current make it ideal for portable and space-constrained designs.
Key Features
Ultra-low ON-resistance (RON) Wide input voltage range High continuous output current capability Controlled slew rate for inrush current limiting Low quiescent current Thermal shutdown protection Reverse current blocking (when disabled) Active high enable pin (ON pin) Compact WQFN package
Electrical Characteristics
Input Voltage Range: 0.5 V to 5.5 V ON-Resistance (RON): Typically ~5 mΩ (VIN = 5 V) Continuous Output Current: Up to 6 A (typical, PCB dependent) Quiescent Current: Typically < 10 µA Shutdown Current: Typically < 1 µA Enable Threshold Voltage: ~0.9 V (typical)
Functional Description
The TPS22995RZGR operates as a load switch that connects or disconnects a power supply to a load using an internal MOSFET controlled by an enable (ON) pin. When the ON pin is asserted high, the device turns on with a controlled rise time, limiting inrush current. When disabled, the switch turns off quickly and prevents reverse current flow from the output to the input. Integrated protection features such as thermal shutdown ensure reliability during abnormal operating conditions.
Absolute Maximum Ratings
Input Voltage (VIN): -0.3 V to 6 V ON Pin Voltage: -0.3 V to 6 V Output Voltage (VOUT): -0.3 V to VIN + 0.3 V Operating Junction Temperature: -40°C to +125°C Storage Temperature: -65°C to +150°C
Package Information
Package Type: WQFN (RZG) Package Size: 3 mm × 3 mm Mounting Type: Surface Mount Pin Count: 12
Applications
Power rail switching Portable electronics USB power distribution Solid-state drives (SSD) Battery-powered systems Embedded systems power management
Advantages
Minimizes power loss due to low RON Reduces system inrush current Enhances system reliability with built-in protections Suitable for high-current, compact designs
