Overview

Description

MIC4690YM is Microchip/Micrel’s single-channel load switch with built-in protection. It provides a protected, controllable power path from a supply to a load, suitable for MCU-driven or portable designs.
Key features (typical): low-voltage operation (roughly 2.7–5.5 V), on-chip current limit, overcurrent protection, thermal shutdown, reverse current protection, undervoltage lockout, and an enable input to turn the switch on/off. Some variants offer fault/status feedback; check the datasheet for exact details.
What it’s used for: powering LEDs, sensors, small motors, or other loads directly from a supply rail while protecting the load and controller from faults or backfeeding.
Package note: the suffix YM indicates a specific Microchip packaging version (an 8-pin small-outline style). For exact pinout, electrical ratings (current limit, delay, dropout), and application guidance, refer to the MIC4690YM datasheet.

Features

Here are the typical features of MIC4690YM (variant-dependent; check datasheet for exact options):
- Low-dropout linear regulator
- Output current up to about 100 mA
- Fixed and adjustable output versions
- Input voltage range: ~2.7 V to 5.5 V
- Very low quiescent current
- Low dropout voltage at rated load
- Internal current limit and thermal/shutdown protection
- Enable/disable control
- Fast transient response
- Available in compact YM package
Note: Exact voltage options, quiescent current, and protection details vary by specific MIC4690YM variant.

Package

MIC4690YM is in an 8-pin small-outline package (SOIC-8).

Pinout

Pin count: 8 pins (YM denotes an 8‑pin package such as MSOP-8/SOIC-8).
Function: High‑side load switch with current‑limit and thermal‑shutdown protection, with an enable input to turn the switch on/off (used to power a load from VIN).

Manufacturer

MIC4690YM is manufactured by Micrel Semiconductor, which is now part of Microchip Technology. Micrel was an American fabless semiconductor company that designs analog and mixed-signal integrated circuits, including power-management and high-performance analog products (acquired by Microchip in 2015).

Application

MIC4690YM is a high-side load switch with current limit and thermal shutdown. Applications:
- Power gating for microprocessors and peripherals in portable/consumer electronics
- Automotive and industrial rails needing overcurrent protection
- Hot-swap and rail sequencing for multi-rail supplies
- LED backlight/display power rails requiring controlled turn-on
- Battery-powered devices needing short-circuit protection and safe shutdown

Equivalent

MIC4690YM is a Micrel/Microchip part; exact equivalents depend on its function (regulator, switch, or supervisor) and the electrical specs. Please specify the function and key specs (Vin, Vout, Iout, dropout, enable, package). I can then give precise cross-references from TI, Analog Devices, ON Semiconductor, ST, etc.
