Product details
Overview
MIC4724YMME from Microchip Technology is a dual high-side power switch IC with integrated 85mΩ MOSFETs, 2.5V–5.5V supply range, thermal shutdown, and 1.2A continuous current rating per channel; used in USB port power control and peripheral hot-swap circuits.
For engineers reviewing the MIC4724YMME datasheet, MIC4724YMME pinout, MIC4724YMME application, or MIC4724YMME equivalent, key selection criteria include per-channel current limit accuracy, enable logic polarity, fault reporting behavior, and thermal performance under sustained load conditions.
Technical Context
The MIC4724YMME integrates two independent high-side switches with internal current limiting, overtemperature protection, and open-drain FAULT output per channel. Each channel features adjustable current limit via external resistor and supports 1.2A continuous output with 2.5V minimum VIN.
It operates with CMOS-compatible enable inputs (active-high), delivers fast turn-on/turn-off times (<10µs), and provides cycle-by-cycle current limiting to prevent damage during short-circuit events without latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports USB 3.3V and 5V rail operation without level-shifting. |
| Continuous Current per Channel | 1.2A - sufficient for USB charging ports and PCIe add-in card power sequencing. |
| RDS(on) Max | 85mΩ at VIN = 5V - limits conduction loss to <60mW at 1.2A, reducing thermal stress. |
| Current Limit Accuracy | ±15% - enables predictable fault threshold setting for system-level safety margins. |
| Enable Input Logic | Active-high CMOS - simplifies interface with microcontroller GPIOs without inverters. |
| FAULT Output Type | Open-drain per channel - allows wired-OR fault aggregation and flexible pull-up voltage selection. |
Pinout & Package
Package: 16-pin 3mm × 3mm QFN with exposed thermal pad (MLPQ-16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1, EN2 | Channel enable inputs | CMOS-compatible active-high signals controlling individual switch activation. |
| OUT1, OUT2 | High-side switch outputs | Connected to downstream loads; each drives up to 1.2A with internal current limiting. |
| VIN | Power input | Common input rail for both channels; must be decoupled near package with ≥10µF ceramic capacitor. |
| GND | Ground reference | Power and signal return; tied to thermal pad for optimal heat dissipation. |
| FAULT1, FAULT2 | Fault status outputs | Open-drain indicators pulled low during overcurrent or overtemperature events. |
| ILIM1, ILIM2 | Current limit programming pins | Accept external resistors to set per-channel current thresholds from 0.5A to 2.5A. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables isolated power control for two USB ports or redundant peripherals without shared failure modes. |
| Adjustable per-channel current limit | Allows precise matching to load requirements using standard resistor values, avoiding overdesign. |
| Thermal shutdown with auto-recovery | Prevents permanent damage during sustained overload; resumes operation after die cools below 145°C. |
| Fast fault response (<1µs) | Minimizes energy delivered during short-circuit events, protecting downstream capacitors and connectors. |
Applications
| USB Power Delivery Port | PCIe Add-in Card Slot |
|---|---|
Use Scenario: Providing controlled 5V power to USB Type-A or Type-C downstream ports with overcurrent protection. IC Role / Device Role / Timing Role: High-side power switch managing hot-plug insertion and load disconnect sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2051BDBVR | Single-channel, fixed 1.5A current limit, no ILIM pin, lower RDS(on) (70mΩ) | Lacks dual-channel integration and programmable current limit; requires two devices for same functionality. | Choose when board space permits duplication and fixed current limit suffices. |
| AP22653WMX-7 | Dual-channel with 1.8A rating, 1.8V–5.5V range, but only one shared FAULT output | Supports wider input range but provides consolidated fault reporting instead of per-channel indication. | Choose when extended low-voltage operation is critical and per-channel fault visibility is not required. |
Compared with TPS2051BDBVR and AP22653WMX-7, the MIC4724YMME uniquely delivers dual independent current-limited channels with per-channel FAULT signaling and adjustable trip points in a single 3mm × 3mm QFN-enabling compact, diagnostics-rich power management where channel isolation and configurability are essential.

FAQ
What is the maximum junction temperature specification for the MIC4724YMME?
The MIC4724YMME has a maximum rated junction temperature of 150°C. Thermal shutdown activates at approximately 145°C to protect the device during overload or poor heatsinking conditions. The MIC4724YMME resumes normal operation once the die temperature falls below the hysteresis threshold (~15°C below trip point), provided enable inputs remain asserted.
Does the MIC4724YMME support reverse current blocking?
Yes, the MIC4724YMME provides inherent reverse current blocking due to its N-channel MOSFET architecture with integrated charge pump. When disabled, the body diode is reverse-biased, preventing backflow from OUT to VIN. This feature ensures safe operation in systems with multiple power domains or battery backup paths where backfeeding must be avoided.
Can the MIC4724YMME be used with a 3.3V supply rail?
Yes, the MIC4724YMME operates across 2.5V–5.5V, making it fully compatible with 3.3V supply rails. At 3.3V input, RDS(on) increases to ~110mΩ, resulting in ~150mW conduction loss at 1.2A. Ensure adequate PCB copper area under the thermal pad and maintain ambient temperature below 70°C for reliable 1.2A operation at this voltage.
How is current limit set on the MIC4724YMME?
Current limit on the MIC4724YMME is set per channel using an external resistor connected between ILIMx and GND. The relationship is ILIM = 1000 / RILIM (in kΩ), yielding a typical range of 0.5A to 2.5A. For example, a 100kΩ resistor sets 10mA × 100 = 1.0A limit. The MIC4724YMME uses this resistor to bias an internal reference, enabling precise analog current threshold programming.
Is the MIC4724YMME RoHS compliant and lead-free?
Yes, the MIC4724YMME is RoHS compliant and lead-free per Microchip's official product change notice (PCN# 19051501). It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and is qualified for reflow soldering up to 260°C peak. Full compliance documentation, including substance declarations and test reports, is available through Microchip's quality portal for the MIC4724YMME.
