MIC2505-1YM-TR

The MIC2505-1YM-TR is a single-channel high-side load switch from Microchip (Micrel) with built‑in current limiting and protections. It is designed to power a load (e.g., LEDs or a power rail) from a DC supply, with easy on/off control via an enable pin.
Key points
- High-side switch with programmable or selectable current limit, suitable for LED drivers and simple power rails.
- Protections include overcurrent/short-circuit protection, undervoltage lockout, thermal shutdown, and reverse-battery protection.
- Status/diagnostic option (fault/flag output) and a fault-safe shutdown when limits are reached.
- Small package and Tape & Reel (TR) option for automated assembly.
Typical use
- Use Vin to supply, Vout to the load, EN to enable/disable, and ILIM (via external resistor) to set the current limit. Useful for LED backlights, portable devices, and power sequencing.

6 pins. It is a single-channel high-side load switch with an enable input. When EN is asserted, IN is connected to OUT to power a load; it includes current‑limit/overcurrent protection with GND as reference (ILIM/FB pin typically used to set/program the limit).

Manufacturer: Micrel, Inc. (now part of Microchip Technology). Micrel was a fabless semiconductor company specializing in analog, mixed-signal and power-management ICs. In 2015, Microchip Technology acquired Micrel, so MIC parts are now marketed under Microchip’s analog/power-management portfolio.

MIC2505-1YM-TR is a high-side load switch with current limit, overcurrent protection, reverse protection, and thermal shutdown. Typical application areas:
- Gating/protecting power rails in portable/consumer electronics and IoT
- Automotive and industrial systems
- Power sequencing for CPUs, GPUs, FPGAs, DSPs, and sensors
- Hot-swap/backplane protection in motherboards and power supplies
- LED backlight/power rails
- Any system requiring safe turn-on/off with fault protection and rail control
