Analog Devices Inc./Maxim Integrated MAX4428MJA/883B

Overview

MAX4428MJA/883B from Maxim Integrated is a dual high-speed MOSFET driver IC with one inverting and one noninverting output stage, rated for -55°C to +125°C operation in 8-pin CERDIP package, delivering 1.5A peak output current, 10ns/25ns typical delay times (tD1/tD2), and 20ns typical rise/fall times into 1000pF load - used in radiation-tolerant motor controllers and MIL-STD-883-compliant DC-DC converters.

For engineers reviewing the MAX4428MJA/883B datasheet, MAX4428MJA/883B pinout, MAX4428MJA/883B application, or MAX4428MJA/883B equivalent, key selection criteria include guaranteed military-grade temperature range (-55°C to +125°C), CERDIP hermetic packaging, dual-output logic configuration (INVA/INVB → OUTA/OUTB), and compliance with MIL-STD-883 Class B processing requirements.

Technical Context

The MAX4428MJA/883B integrates two independent gate drivers on a single die: one inverting stage (INA → OUTA) and one noninverting stage (INB → OUTB), each capable of sourcing/sinking 1.5A peak current. Its output resistance is specified at 4Ω (typ) over full temperature range, enabling fast charging/discharging of large MOSFET gate capacitances while maintaining rail-to-rail swing within ±25mV.

Delay times (tD1 = 10–40ns, tD2 = 25–60ns) and transition times (tR/tF = 20–40ns) are characterized across VDD = 4.5V to 18V and TA = -55°C to +125°C, with supply current ranging from 0.3mA (both inputs low) to 8.0mA (both inputs high) - optimized for high-frequency switching in harsh-environment power conversion.

FAQ

What does the "/883B" suffix indicate in MAX4428MJA/883B?

The "/883B" suffix denotes full compliance with MIL-STD-883B, Class B testing and processing - including burn-in, temperature cycling, mechanical shock, and hermeticity verification. MAX4428MJA/883B undergoes these tests per Method 5005 and Method 5011, ensuring suitability for defense and space applications where reliability under extreme environmental stress is mandatory.

Is MAX4428MJA/883B pin-compatible with MAX4428EJA or MAX4428CSA?

Yes, MAX4428MJA/883B shares identical 8-pin CERDIP pinout with MAX4428EJA and matches the functional pin mapping of MAX4428CSA (SO-8), but physical package dimensions and thermal characteristics differ. PCB layout must accommodate CERDIP footprint and thermal mass; SO-8 variants require rework for direct replacement.

What is the maximum capacitive load the MAX4428MJA/883B can drive reliably?

MAX4428MJA/883B is characterized up to 1000pF load with 20–40ns rise/fall times. For loads exceeding 1000pF, transition times increase linearly; driving >5nF may require external gate resistors or paralleled drivers. Data sheet confirms stable operation with 1000pF at 18V, -55°C to +125°C - sufficient for most discrete and module-based power FETs.

Does MAX4428MJA/883B require external bypass capacitors, and if so, what values?

Yes - MAX4428MJA/883B demands local bypassing: a 4.7µF low-ESR capacitor in parallel with a 0.1µF ceramic capacitor, placed within 5mm of pins 6 (VDD) and 3 (GND). This mitigates 3A peak supply transients and prevents ground bounce that degrades tD1/tD2 and tR/tF performance - omission risks timing instability and output ringing.

Can unused inputs on MAX4428MJA/883B be left floating?

No - unused inputs on MAX4428MJA/883B must be tied to GND. Floating inputs risk violating the 50ns maximum dwell time between VIH (2.4V) and VIL (0.8V), causing excessive supply current, erratic output behavior, or thermal overstress. Grounding unused inputs reduces quiescent current to 0.3–0.6mA and ensures deterministic logic states.
