Overview
The MIC2091-2YM5-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a P-channel MOSFET with an output current limit of 100mA and a maximum on-resistance of 1.2 ohms. The device operates within a load voltage range of 1.8V to 5.5V and supports non-inverted input control. Key protection mechanisms include latch-off overcurrent protection, short-circuit protection, and thermal shutdown. It is housed in a surface-mount SOT-23-5 package and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a P-channel power switch with integrated current limiting and latch-off fault protection.
- Provides comprehensive safety features including short-circuit protection and thermal shutdown capabilities.
- Supports high-side switching applications with a non-inverted logic interface for easy control.
Applications
- Power distribution in portable consumer electronics
- Load switching in industrial control systems
- Peripheral power management in embedded computing devices
Procurement Notes
Verify the specific suffix YM5 against the manufacturer's latest datasheet to confirm pinout compatibility and electrical characteristics. Ensure that the latch-off feature aligns with system reset requirements, as this differs from auto-restart variants. Confirm RoHS compliance status and check for any recent PCN updates regarding assembly or material changes before finalizing procurement.
Selection Notes
Select this component when a high-side switch with permanent latch-off protection is required to isolate faults completely. Compare the 1.2 ohm on-resistance against system power loss constraints. Consider the operating temperature range and package size relative to PCB space limitations. Evaluate if the latch-off behavior suits the application compared to auto-restart alternatives like the MIC2091-1YM5-TR.
Part Context
This part belongs to the MIC209x series of power distribution switches from Microchip Technology (formerly Micrel). The series includes variants with different current limits and protection behaviors, such as auto-restart versus latch-off. The MIC2091-2YM5-TR specifically denotes the 100mA current limit version with latch-off functionality in a SOT-23-5 package.
Replacement Considerations
MIC2091-1YM5-TR offers similar specifications but features auto-restart current limiting instead of latch-off protection. Verify if the system can tolerate automatic recovery from fault conditions. Other MIC209x variants may differ in current ratings or package types; consult the official datasheet for direct pin-to-pin compatibility and electrical equivalence.
