MIC2090-2YM5-TR

Product Overview

Microchip Technology MIC2090-2YM5-TR is a surface-mount P-channel high-side power switch with a 1:1 input-to-output ratio and one output. It switches loads from 1.8 V to 5.5 V, supports up to 50 mA, and uses an On/Off non-inverting input with a status flag. The device is specified for junction temperatures from -40°C to 125°C in a SOT-23-5 package.

Key Features

• P-channel high-side switch topology with a 1:1 input-to-output ratio and one output.
• Load voltage range of 1.8 V to 5.5 V and maximum output current of 50 mA.
• Typical on-resistance of 700 mΩ, On/Off non-inverting input, and status flag.
• Latch-off current-limit recovery and operating junction temperature range of -40°C to 125°C.
• No separate supply voltage is required.
• Surface-mount SOT-23-5 package (SC-74A, SOT-753).

Applications

• Switching low-current loads in portable electronics.
• Controlling power to sensors or small peripherals from a single On/Off signal.
• Load switching where a status flag is available for monitoring.

Design & Procurement Notes

Designers should verify that the load current remains at or below 50 mA and that the load voltage stays within 1.8 V to 5.5 V. The non-inverting On/Off input and status flag should be connected to match the required control and monitoring behavior. Latch-off current-limit recovery affects fault handling, so system protection strategy should account for it. The -40°C to 125°C junction temperature range and SOT-23-5 surface-mount package should be considered during thermal and PCB layout planning.
