Microchip Technology, Inc. Power Distribution Switches, Load Drivers MIC94083YFT-TR

The MIC94083YFT-TR is a high-side load switch designed for applications requiring efficient power distribution. It operates within an input voltage range of 1.7V to 5.5V and supports a continuous operating current of up to 2A. The device features a low on-resistance of 67 m,Ѷ, which contributes to reduced power loss during operation. This load switch includes an internal level shift for compatibility with CMOS/TTL control logic and offers a micropower shutdown mode to minimize quiescent current. The MIC94083YFT-TR also incorporates a soft-start feature with a controlled turn-on time of 800 ¬µs, helping to prevent inrush current that could affect the input supply voltage. Additionally, it has an active load discharge circuit that engages a 250,Ѷ load when the switch is disabled, ensuring rapid discharge of capacitive loads. The device is housed in a compact 0.85mm x 0.85mm FTDFN package, making it suitable for space-constrained applications such as portable devices, including cellular phones, personal media players, and portable instrumentation. Its operational temperature range spans from -40¬8C to +125¬8C, allowing for versatility in various environmental conditions.
