Product details
Overview
MAX17604ASA+ from Maxim Integrated is a dual-channel, noninverting MOSFET gate driver IC designed for high-frequency power switching applications. It delivers 4A peak sink/source current per channel, features 12ns typical propagation delay with matched delays between channels, and operates from a +4V to +14V single supply. It is used in synchronous buck converters to drive high-side and low-side N-channel MOSFETs with precise timing control.
For engineers reviewing the MAX17604ASA+ datasheet, MAX17604ASA+ pinout, MAX17604ASA+ application, or MAX17604ASA+ equivalent, key selection considerations include its HNM (high-noise margin) CMOS-compatible logic inputs, enable-controlled dual outputs, thermal shutdown protection, and SO-8 package compatibility with industrial-grade -40°C to +125°C operation.
Technical Context
The MAX17604ASA+ implements dual independent predriver stages with internal level-shifting and shoot-through prevention logic. Its input stage accepts HNM logic thresholds (VIH = 4.25V, VIL = 2.0V) with 0.9V hysteresis, enabling robust noise immunity in noisy power-converter environments.
Each output stage provides matched 12ns propagation delay (tD-ON/tD-OFF), 6ns rise/5ns fall time into 1nF, and 4A peak current capability. Internal UVLO (3.5V typ, 200mV hysteresis) ensures safe startup, while thermal shutdown protects against sustained overload conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +4V to +14V single supply - supports wide-input DC-DC designs without auxiliary bias rails. |
| Peak Output Current | 4A sink/source per channel - drives large gate capacitances (e.g., >10nF) at high switching frequencies. |
| Propagation Delay | 12ns typical (tD-ON/tD-OFF) - enables >50MHz effective switching control in resonant topologies. |
| Input Logic Type | HNM CMOS-compatible (VIH = 4.25V, VIL = 2.0V) - eliminates need for external level shifters when interfacing with microcontrollers or PWM controllers. |
| Rise/Fall Time | 6ns/5ns into 1nF load - minimizes transition losses and EMI generation during MOSFET switching. |
| Operating Temperature | -40°C to +125°C junction - qualified for under-hood automotive and industrial power module use. |
| UVLO Threshold | 3.5V typical with 200mV hysteresis - prevents erratic operation during brown-out conditions. |
Pinout & Package
MAX17604ASA+ is housed in an 8-pin SO (Small Outline) package (Package Code: S8+2, Outline Number: 21-0041), with exposed pad not present. The package is RoHS-compliant and rated for JEDEC-standard thermal performance (θJA = 136°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ENA | Enable input for Channel A | Internally pulled up to VDD via 100kΩ resistor; drives OUTA low when grounded - enables independent channel disable for burst-mode or phase-shedding control. |
| 2 - INA | Noninverting logic input for Channel A | HNM-compatible (VIH = 4.25V); directly interfaces with 3.3V/5V controllers without level translation. |
| 3 - GND | Power and signal ground reference | Primary return path for 4A peak output currents; requires low-inductance PCB grounding to prevent shoot-through risk. |
| 4 - INB | Noninverting logic input for Channel B | Functionally identical to INA; supports complementary or independent PWM inputs for half-bridge or dual-phase operation. |
| 5 - OUTB | Channel B driver output | 4A capable push-pull stage; sources/sinks current to charge/discharge MOSFET gate capacitance rapidly. |
| 6 - VDD | Single positive power supply input | +4V to +14V range; requires local 2.2µF ceramic bypass capacitor placed adjacent to pin to suppress high-di/dt transients. |
| 7 - OUTA | Channel A driver output | Matched to OUTB in delay (≤8ns inter-channel skew) - critical for synchronous rectification and zero-voltage switching timing accuracy. |
| 8 - ENB | Enable input for Channel B | Same internal pull-up as ENA; allows independent gating of second channel for interleaved or fault-isolation schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual noninverting outputs with independent enables | Enables flexible half-bridge, dual-phase, or redundant driver configurations without external logic inversion. |
| 4A peak sink/source per channel | Drives high-Qg MOSFETs (e.g., 100nC) at >1MHz with sub-10ns transitions - reduces conduction loss in high-efficiency SMPS. |
| 12ns propagation delay with matched channels | Ensures <8ns inter-channel skew - essential for minimizing dead-time uncertainty in synchronous buck and LLC converters. |
| HNM CMOS input logic with 0.9V hysteresis | Rejects >1V noise spikes on control lines - improves reliability in electrically noisy motor-drive or automotive power systems. |
| Thermal shutdown protection | Shuts down both outputs if junction temperature exceeds +150°C - prevents latch-up or permanent damage during overload or poor heatsinking. |
| UVLO with 200mV hysteresis | Guarantees clean startup and shutdown behavior across varying input voltage ramps - avoids partial turn-on states that cause shoot-through. |
Applications
| High-Frequency Synchronous Buck Converter | Industrial DC-DC Power Module |

FAQ
What logic levels does the MAX17604ASA+ accept?
The MAX17604ASA+ uses CMOS-like high-noise margin (HNM) inputs with VIH = 4.25V (min) and VIL = 2.0V (max), plus 0.9V hysteresis. This allows direct interface with 3.3V and 5V controllers while rejecting common-mode noise up to ±1V - a key advantage over TTL-input drivers in noisy power systems. The MAX17604ASA+ does not require external level shifters for standard microcontroller PWM outputs.
Does the MAX17604ASA+ support independent channel enable control?
Yes, the MAX17604ASA+ provides dedicated ENA and ENB pins, each internally pulled up to VDD via a 100kΩ resistor. Driving either pin low disables its respective output (OUTA or OUTB) independently. This enables phase shedding in multiphase converters, fault isolation in redundant power stages, or burst-mode operation - all without modifying upstream control logic. The MAX17604ASA+ maintains full shoot-through protection even during partial enable states.
What is the thermal performance of the MAX17604ASA+ in SO-8 package?
The MAX17604ASA+ in SO-8 package has a junction-to-ambient thermal resistance (θJA) of 136°C/W on a standard 4-layer PCB, and junction-to-case (θJC) of 38°C/W. At 70°C ambient, its continuous power dissipation limit is 588.2mW (derated 74mW/°C above +70°C). These values are validated per JEDEC 51 standards and confirm suitability for convection-cooled industrial modules where heatsinking is impractical. The MAX17604ASA+ integrates thermal shutdown to protect against transient overloads.
How does the MAX17604ASA+ prevent shoot-through in half-bridge configurations?
The MAX17604ASA+ incorporates internal logic-based break-before-make (BBM) circuitry that enforces a minimum dead-time during output-state transitions - preventing simultaneous conduction of high-side and low-side MOSFETs. This hardware-level protection operates independently of input timing and remains active across the full -40°C to +125°C range. Unlike software-based dead-time insertion, the BBM function in the MAX17604ASA+ guarantees shoot-through immunity even under fast input edge rates or supply transients.
Can the MAX17604ASA+ drive MOSFETs with >10nF total gate charge?
Yes, the MAX17604ASA+ delivers 4A peak sink/source current and achieves 40ns rise/fall times into 10nF loads at VDD = 14V - verified in the datasheet's switching characteristics table. For such high-capacitance gates, the MAX17604ASA+ requires proper PCB layout: localized 10µF+ storage capacitance near VDD, minimized loop inductance, and direct low-impedance GND routing. The MAX17604ASA+'s matched 12ns propagation delay ensures consistent timing even under heavy capacitive loading.
