Data sheet:
The TPS22991I is a small, low RON, single channel load switch with controlled slew rate. The device contains an N-channel MOSFET that operates over an input voltage range of 1.0V to 5.5V and supports a maximum continuous current of 3A. The switch is controlled by an on and off input, which is capable of interfacing directly with low-voltage control signals.
For space constrained, battery powered applications, the device is suitable due to its small size and low RON. The wide input voltage range of the switch applies to many different voltage rails. The controlled rise time of the device greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop. The TPS22991I further reduces the total solution size by integrating a 150Ω pulldown resistor for quick output discharge (QOD) when the switch is turned off.
The TPS22991I is available in a small, space saving 0.85mm × 0.75mm, 0.4mm pitch, 4-pin UQFN package. The device is characterized for operation over the free-air temperature range of –55°C to +125°C.
- Integrated single channel load switch

- Maximum continuous switch current: 2.7A
- Typical ON-resistance: 28mΩ
- Low quiescent current:
- IQ at 3.3V VIN = 6µA (typical)
- Ultra-low shutdown current:
- ISD at 3.3V VIN = 200nA (maximum)
- Controlled slew rate:

- Version C, CN: rise time (tR) at 3.3V VIN = 662µs
- Quick output discharge (QOD): 150Ω
- Thermal shutdown protection
- UQFN package: 0.85 × 0.75mm, 0.4mm pitch
