MIC94045YFL-TR Description

Short technical summary and product information.

The MIC94045YFL-TR from Microchip Technology is a high-side load switch designed for efficient power management in portable and battery-powered systems. It features an internal 28mΩ RDSON P-channel MOSFET, enabling it to handle up to 3A of continuous current.

 

The device operates from an input voltage range of 1.7V to 5.5V, making it suitable for applications powered by Lithium-ion, NiMH, NiCad, or Alkaline batteries. It supports 1.5V logic-level control and includes a slew rate controlled soft-start function with a typical turn-on time of 1ms to prevent input voltage dips during in-rush current events.

 

A key feature of the MIC94045YFL-TR is its active load discharge circuit. When the switch is disabled, this circuit automatically discharges capacitive loads by switching in a 200Ω load, ensuring a safe shutdown.

 

Packaged in a compact 1.2mm x 1.2mm 4-pin MLF® package, the MIC94045YFL-TR is ideal for space-constrained designs. It offers ultra-low quiescent current and micro-power shutdown current to maximize battery life. The operating junction temperature range is from -40°C to +125°C.
