TPS22998
Product Details
describe:
The TPS22998 is an AOD454A single-channel load switch that provides a configurable rise time to minimize inrush current. The device contains an N-channel MOSFET that operates over an input voltage range of 0.2 V to 5.5 V and supports up to 10 A continuous current.
The switch is controlled by an on and off input (ON) which can be connected directly to a low voltage control signal (V IH = 0.9 V). The TPS22998 has a fixed fast output discharge when the switch is off, pulling the output down to ground.
The TPS22998 is available in a 1.5 × 2.0 mm, 0.5 mm pitch, 10-lead WQFN package (RYZ) and operates over the natural air temperature range of –40°C to +105°C.
