MAX15024AATB+T Обзор
A low-side MOSFET gate driver is a power-management IC that sits between a low-power control signal (from a microcontroller, PWM controller, or logic gate) and the gate of a power MOSFET or IGBT. It provides high peak source/sink current to quickly charge and discharge the MOSFET gate capacitance, enabling fast switching transitions. Gate drivers belong to the broader category of power MOSFET drivers within power management ICs, and they are essential building blocks in switch-mode power supplies (SMPS), motor drives, Class-D amplifiers, synchronous rectifiers, and DC-DC converters where direct logic-level drive is too weak.
Key features of the MAX15024 include independent source and sink output transistors, internal logic to prevent shoot-through, and a thermally enhanced exposed-pad package that dissipates switching losses efficiently. The TTL input thresholds make it compatible with 3.3V and 5V microcontrollers without level shifters, while the wide 4.5V to 28V operating range suits 5V, 12V, and 24V industrial bus rails. The driver can deliver 8A peak (typical) into the gate of large power MOSFETs, dramatically reducing switching loss and improving power-conversion efficiency at high frequencies.
Internally, the MAX15024AATB+T uses a BiCMOS process to combine low-power CMOS logic with high-current bipolar output stages. The split source/sink output paths allow designers to independently tune rise and fall times by inserting series resistors between the IC outputs and the MOSFET gate, providing fine-grained control of EMI and switching loss trade-offs. The exposed thermal pad connects to the driver ground and serves as the primary heat-dissipation path, allowing the part to sustain high-frequency switching without thermal shutdown.
Typical applications include synchronous rectification in isolated DC-DC converters, high-current Class-D audio amplifiers, motor-driver H-bridges, and power-ORing circuits. The MAX15024 is also widely used as an auxiliary gate driver in telecom brick converters, industrial 24V-input power modules, and digital-control systems requiring fast, high-current MOSFET switching.
When designing with this part, place input and bypass capacitors close to the VDD pin and route the high-current gate-drive traces as short and wide as possible to minimize parasitic inductance. The exposed pad must be soldered to a sufficiently large copper pour (typically 1 square inch) to keep junction temperature within the -40C to +125C operating range during continuous 1 MHz switching.

Типичное применение
MAX15024AATB+T подходит для 6 применениеs: Synchronous Rectification in DC-DC Converters, Class-D Audio Amplifier Output Stage, Brushless DC Motor Drive H-Bridge, Telecom Isolated Brick Converter, Power OR-ing and Hot-Swap Controller, High-Frequency SMPS for Industrial Automation.
Synchronous Rectification in DC-DC Converters
The MAX15024AATB+T drives the low-side synchronous rectifier MOSFET in buck, forward, and half-bridge converters where replacing rectifier diodes with MOSFETs cuts conduction loss and improves efficiency. Its 8 A peak sink current discharges the synchronous FET gate capacitance in nanoseconds, minimizing dead time and reverse-recovery losses at switching frequencies up to 1 MHz. The 16 ns propagation delay keeps the synchronous FET switching tightly aligned with the primary-side control signal, while the 4.5 V to 28 V supply range supports 5 V, 12 V, and 24 V input rails. Designers typically insert small gate resistors between the IC output and the FET gate to tune dV/dt and limit ringing. Unlike integrated synchronous-rectifier controllers, this part provides direct gate-drive flexibility for non-standard topologies and high-current rails.

Class-D Audio Amplifier Output Stage
In Class-D audio amplifiers, the MAX15024AATB+T drives the half-bridge output MOSFETs that deliver hundreds of watts to a low-impedance loudspeaker load. Its 8 A peak source/sink current charges and discharges the large gate capacitance of audio-grade power MOSFETs within nanoseconds, preserving the PWM edge fidelity that determines audio THD+N performance. The TTL input thresholds allow direct connection to 3.3 V or 5 V modulator DSPs without external level shifters. The wide 4.5 V to 28 V supply range covers single-supply designs powered from 12 V or 24 V rails in automotive and prosumer audio. The 10-pin TDFN-EP footprint places the gate driver adjacent to the output MOSFETs, minimizing parasitic gate-loop inductance that would otherwise cause ringing and EMI.

Brushless DC Motor Drive H-Bridge
The MAX15024AATB+T drives the low-side switches of a three-phase brushless DC (BLDC) or permanent-magnet synchronous motor (PMSM) inverter where each phase leg requires a high-current gate driver with low propagation delay. The 8 A peak source/sink capability handles the gate charge of 40 V to 100 V N-channel MOSFETs in small to medium-power motor drives (up to ~1 kW). Its 16 ns propagation delay ensures precise commutation timing, reducing torque ripple and acoustic noise. The TTL input thresholds interface directly to FOC algorithm microcontrollers and 3.3 V logic gate drivers. The exposed pad package efficiently dissipates switching loss during continuous 20 kHz to 100 kHz PWM operation typical of motor drives.

Telecom Isolated Brick Converter
In isolated telecom brick converters (typically 48 V input, 1 V to 12 V output at hundreds of amps), the MAX15024AATB+T drives the synchronous rectifier MOSFETs on the secondary side of the isolation barrier. The 4.5 V to 28 V supply range covers secondary-side rails derived from the transformer output, while the 8 A peak drive handles large FET arrays in parallel. The 16 ns propagation delay keeps synchronous-rectifier timing aligned with the primary-side PWM, critical for high-efficiency (>95%) telecom power modules. The compact 10-pin TDFN-EP package allows placement close to the synchronous FETs on the secondary side, minimizing PCB loop area and reducing conducted EMI.

Power OR-ing and Hot-Swap Controller
The MAX15024AATB+T drives the OR-ing MOSFETs in redundant power-supply architectures where two or more DC sources feed a common load. Its 8 A peak drive quickly turns off the OR-ing FET when its source voltage drops below the common rail, preventing reverse-current backflow that would damage upstream supplies. The TTL inputs accept logic-level enable signals from a hot-swap controller, and the 16 ns propagation delay provides fast disconnect during fault events. The 4.5 V to 28 V range covers 12 V and 24 V redundant rails in server, telecom, and industrial systems. The compact 3x3 mm TDFN-EP footprint allows high-density OR-ing designs in blade servers and modular power shelves.

High-Frequency SMPS for Industrial Automation
In industrial 24 V-bus SMPS modules, the MAX15024AATB+T drives the primary-side low-side MOSFET in hard-switched flyback, forward, or half-bridge converters operating at 250 kHz to 1 MHz. The 8 A peak drive enables fast turn-on and turn-off of the primary MOSFET, reducing switching loss and improving power-conversion efficiency. The 4.5 V to 28 V supply range accepts 24 V industrial bus rails directly, eliminating auxiliary supply rails. The TTL input thresholds allow direct connection to industrial PWM controllers such as the UC2843 or UCC28C42. The exposed thermal pad dissipates switching loss into PCB copper, sustaining continuous high-frequency operation in factory-automation equipment, programmable-logic controllers, and motor-driver auxiliary supplies.

Заметки по проектированию
Solder the exposed thermal pad (EP) to a PCB copper pour of at least 1 square inch connected to ground. At 1 MHz switching into large multi-nC MOSFET gates, switching loss in the driver can rise to 200 mW to 500 mW; without adequate copper, the junction temperature may exceed the 125 C rating. Estimated: at 0.5 W dissipation, a 30 C/W theta_JA copper pour yields a 15 C temperature rise above ambient, which is safe; smaller pours require thermal verification.
Route the high-current gate-drive traces (SOURCE_OUT, SINK_OUT) as short and wide as possible, ideally directly above the MOSFET gate pads. Minimize parasitic gate-loop inductance by placing the driver within 10 mm of the driven MOSFET. Use a 100 nF ceramic bypass capacitor within 2 mm of the VDD pin and a 1 uF to 10 uF bulk capacitor on the same node for high-frequency decoupling. According to manufacturer application guidance, gate-loop inductance above 10 nH causes ringing that increases EMI and may violate dV/dt targets.
Place a small gate resistor (typically 1 ohm to 10 ohm) in series with both SOURCE_OUT and SINK_OUT to independently control rise and fall times. This slows the gate-edge transition to manage dV/dt, ringing, and EMI without compromising overall efficiency. According to the Analog Devices datasheet, the split source/sink outputs allow asymmetric rise and fall time tuning, which is useful for reducing body-diode conduction loss in half-bridge applications. Keep the resistor physically close to the driver output pin.
Do not leave the exposed pad floating; it must be soldered to the PCB ground plane for thermal dissipation and electrical reference. Do not exceed the 28 V absolute maximum VDD rating - inductive ringing on the supply rail can exceed this during turn-off of large MOSFETs; add a local 100 nF + 1 uF bypass network. According to manufacturer guidance, never apply input signals before VDD is present; the input structure is referenced to VDD and undefined behavior can occur during power-up sequencing. For TTL A-version parts, ensure logic-high input is above 2.0 V; for CMOS B-version parts, ensure logic-high is above 0.7 x VDD.
