概述

Description

The MIC94040YFL-TR is a single-channel, high-side load switch from MICREL (now Microchip) with built-in current limiting and protection. It provides a fixed current-limit and fault protections (thermal shutdown, reverse current protection) plus an enable/shutdown input, enabling simple power gating with low quiescent current. It’s suitable for hot-swap protection, LED Driver/strings, and battery-powered circuitry where you want to safely limit fault current to downstream loads. The YFL suffix denotes a specific package variant, and TR indicates Tape-and-Reel packaging. For exact electrical specs (input voltage range, current-limit value, on-resistance, enable logic, quiescent current) and pinout, consult the datasheet on Microchip/Micrel’s site or from distributors.

Package

8-pin MSOP package (MSOP-8), in Tape & Reel (TR).

Pinout

Pin count: 8 pins (8-pin package, e.g., MSOP-8/SO-8, VFL/TR style).
Function: High-side load switch with current limiting and thermal shutdown; includes an enable input to turn the switch on/off, providing Vin to the load with protection against overcurrent.

Manufacturer

Manufacturer: Microchip Technology Inc. (brand used for Micrel parts after Microchip’s acquisition; MIC94040YFL-TR is a Micrel/Microchip part).
What kind of company: Microchip is a global semiconductor company that designs, manufactures, and sells microcontrollers, analog and mixed-signal ICs, memory, and other embedded-system products.

Application

- High-side load switch with current limit
- Power-gating for battery-powered devices (on/off control with protection)
- Rail sequencing and protection for microcontrollers/peripherals
- LED driver or backlighting switch
- Automotive and consumer electronics power distribution with fault protection
- Hot-swap/soft-start for safe power-up and rail isolation
