TPS22902BYFPR

The Texas Instruments TPS22902BYFPR is an integrated P-Channel load switch designed for low input voltage applications, operating from 1 V to 3.6 V. This device features a low ON-resistance, with typical values as low as 78 mΩ at 3.6 V input. It can handle a maximum continuous switch current of 0.5 A.

The TPS22902BYFPR boasts very low quiescent current of 82 nA at 1.8 V and a shutdown current of 44 nA at 1.8 V, making it suitable for power-sensitive applications. It includes features like controlled slew rate to avoid inrush currents and quick output discharge. The device is housed in a compact, four-pin wafer-chip-scale DSBGA package measuring 0.8 mm x 0.8 mm with a 0.4 mm pitch and 0.5 mm height.

This load switch is designed for applications requiring efficient power management and protection. Its low ON-resistance and low quiescent current contribute to reduced power consumption and heat generation. The controlled rise time helps manage inrush current, protecting downstream components during power-up.

Key electrical characteristics include a typical ON-resistance of 78 mΩ at 3.6 V, a maximum continuous switch current of 0.5 A, and a wide operating temperature range of -40°C to 85°C. The device also offers ESD protection tested per JESD 22 standards.
