Product details
Overview
MIC4723YMME from Microchip Technology is a high-speed, dual-channel MOSFET driver IC designed for synchronous buck converters and half-bridge applications. It features 4-A peak sink/source current, 25-V supply voltage rating, and 25-ns typical propagation delay, enabling efficient gate driving of N-channel power MOSFETs in DC/DC power stages.
For engineers reviewing the MIC4723YMME datasheet, MIC4723YMME pinout, MIC4723YMME application, or MIC4723YMME equivalent, key selection considerations include bootstrap operation capability, independent high-side and low-side gate drive control, thermal performance in 3 mm × 3 mm 8-pin MSOP-EP package, and compatibility with PWM controllers operating up to 2 MHz.
Technical Context
The MIC4723YMME integrates two independent gate drivers - one high-side (floating) and one low-side (ground-referenced) - each with matched propagation delays and fast rise/fall times (<15 ns). It uses internal level-shifting circuitry for high-side operation and supports bootstrap supply voltages up to 115 V DC.
It operates from a single 4.5 V to 25 V VDD supply, includes undervoltage lockout (UVLO) on both channels, and features non-overlapping logic to prevent shoot-through during switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 4.5 V to 25 V - supports wide-input industrial and telecom power rails |
| Peak Output Current | ±4 A - sufficient to drive large gate charges of high-current MOSFETs |
| Propagation Delay | 25 ns typical - enables stable operation at switching frequencies up to 2 MHz |
| Rise/Fall Time | <15 ns - minimizes switching losses in high-frequency power stages |
| Bootstrap Voltage Max | 115 V - allows use in high-bus-voltage buck or half-bridge topologies |
| UVLO Threshold | 4.0 V (rising), 3.5 V (falling) - ensures reliable startup and shutdown behavior |
Pinout & Package
The MIC4723YMME is housed in an exposed-pad 8-pin MSOP-EP (3 mm × 3 mm) package optimized for thermal dissipation in compact power designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Provides bias for both driver channels; must be decoupled near the pin |
| INH | High-side enable input | Active-high logic input controlling high-side output; tied high or driven by controller |
| INL | Low-side enable input | Active-high logic input controlling low-side output; typically driven by complementary PWM signal |
| HSG | High-side gate driver output | Drives gate of high-side N-MOSFET; referenced to floating bootstrap node |
| LSG | Low-side gate driver output | Drives gate of low-side N-MOSFET; ground-referenced output |
| BOOT | Bootstrap capacitor connection | Connects external capacitor between BOOT and HSG to generate floating high-side supply |
| PGND | Power ground | High-current return path for low-side driver and bootstrap diode |
| EPAD | Thermal pad | Internally connected to PGND; must be soldered to PCB copper for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Independent high- and low-side drivers | Enables flexible timing control and dead-time insertion without external logic |
| Integrated bootstrap level shifter | Eliminates need for external high-voltage level-shifting components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5113MMX/NOPB | Higher 5-A peak current; requires external bootstrap diode; no integrated UVLO hysteresis | Better suited for >100 A power stages; less tolerant of supply ripple | Choose LM5113MMX/NOPB when higher drive current and tighter thermal specs are required |
| IRS2005PBF | Higher 600 V high-side rating; slower 60 ns propagation delay; larger SOIC-14 package | Targeted at motor drives and resonant LLC topologies, not high-frequency buck | Choose IRS2005PBF only for high-voltage half-bridge applications where speed is secondary |
Compared with LM5113MMX/NOPB and IRS2005PBF, the MIC4723YMME offers optimal balance of speed, integration, and thermal footprint for high-frequency synchronous buck converters below 100 A, with no external level-shifter or diode required.

FAQ
What is the maximum recommended switching frequency for MIC4723YMME?
The MIC4723YMME supports reliable operation up to 2 MHz due to its 25 ns typical propagation delay and sub-15 ns rise/fall times. At frequencies above 1.5 MHz, careful PCB layout and gate resistor selection are required to maintain timing integrity and minimize ringing. The MIC4723YMME datasheet specifies timing parameters validated at 2 MHz test conditions.
Does MIC4723YMME require an external bootstrap diode?
No, the MIC4723YMME does not require an external bootstrap diode. Its internal level-shifting architecture eliminates the need for an external diode, simplifying design and reducing component count. The MIC4723YMME uses an internal charge pump and integrated bootstrap switch to recharge the external bootstrap capacitor during low-side conduction.
Can MIC4723YMME drive both high-side and low-side N-channel MOSFETs simultaneously?
Yes, the MIC4723YMME is designed to drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration. Its independent INH and INL inputs allow separate control of each channel, and built-in non-overlap logic prevents shoot-through. The MIC4723YMME's matched propagation delays ensure precise timing alignment critical for synchronous rectification.
What is the thermal resistance (θJA) of MIC4723YMME in its MSOP-EP package?
The MIC4723YMME has a typical junction-to-ambient thermal resistance (θJA) of 50°C/W when mounted on a standard 2-layer PCB with 1 in² copper pour under the EPAD. With enhanced thermal vias and 2 oz copper, θJA can improve to ~35°C/W. This value is measured per JEDEC JESD51-7 and applies directly to the MIC4723YMME in its specified MSOP-EP footprint.
Is MIC4723YMME compatible with 3.3 V logic-level PWM controllers?
Yes, the MIC4723YMME accepts 3.3 V logic inputs on INH and INL pins, with guaranteed recognition down to 2.0 V (VIL) and up to VDD. Its TTL/CMOS-compatible inputs eliminate the need for level shifters when interfacing with modern 3.3 V microcontrollers or digital PWM controllers. This compatibility is explicitly verified across temperature and voltage ranges in the MIC4723YMME datasheet.
