Analog Devices Inc./Maxim Integrated MAX15070BEUT+

Overview

MAX15070BEUT+ from Maxim Integrated is a high-speed dual-output MOSFET driver IC with independent 3A source (p-channel) and 7A sink (n-channel) capability, 12ns typical propagation delay, CMOS-like HNM logic inputs, and operation from +6V to +14V supply-designed for precise gate control in synchronous buck converters and half-bridge motor drivers.

For engineers reviewing the MAX15070BEUT+ datasheet, MAX15070BEUT+ pinout, MAX15070BEUT+ application, or MAX15070BEUT+ equivalent, key selection criteria include matched input delays (<500ps), shoot-through prevention logic, thermal shutdown at +166°C, low 10pF input capacitance, and SOT23-6 package compatibility with high-density PCB layouts.

Technical Context

The MAX15070BEUT+ integrates complementary open-drain outputs: P_OUT (p-channel, 3A peak source) and N_OUT (n-channel, 7A peak sink), enabling independent optimization of MOSFET turn-on and turn-off timing. Its internal break-before-make control prevents shoot-through during state transitions.

It features HNM logic inputs (VIH = 4.25V min, VIL = 2.0V max) with ±16V input voltage tolerance regardless of V+, 200mV UVLO hysteresis, and thermal shutdown with 13°C hysteresis-ensuring robust operation in noisy industrial power systems.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for MAX15070BEUT+?

The MAX15070BEUT+ has an absolute maximum V+ rating of +16V, but its specified operating supply range is +6V to +14V. Operation below +6V is not guaranteed-unlike the MAX15070A variant-and may result in undefined UVLO behavior or reduced output drive strength. Always maintain V+ within +6V to +14V for full specification compliance in the MAX15070BEUT+.

Does MAX15070BEUT+ support both inverting and noninverting logic inputs simultaneously?

Yes, MAX15070BEUT+ supports simultaneous use of IN+ (noninverting) and IN- (inverting) inputs per its truth table. When both inputs are driven, the output state follows the logical combination: e.g., IN+ = H and IN- = L activates P_OUT (turn-on), while IN+ = L and IN- = H forces N_OUT (turn-off). This enables flexible control modes including enable/disable, polarity selection, and dead-time insertion without external logic.

How does the break-before-make feature function in MAX15070BEUT+?

The MAX15070BEUT+ implements hardware-enforced break-before-make timing with a guaranteed minimum 2ns dead time between P_OUT turn-off and N_OUT turn-on (and vice versa). This is achieved via internal delay circuitry-not software-configurable-and prevents simultaneous conduction in half-bridge or synchronous rectifier topologies, eliminating shoot-through current even during fast input transitions or supply transients.

Can MAX15070BEUT+ drive GaN HEMTs effectively?

Yes, MAX15070BEUT+ is well-suited for driving enhancement-mode GaN HEMTs due to its 7A sink/3A source capability, 12ns propagation delay, and low 10pF input capacitance-enabling clean, fast gate transitions with minimal ringing. Its +6V to +14V supply range aligns with common GaN gate drive requirements, and the 2ns break-before-make timing helps avoid Miller-induced false turn-on in high-dV/dt applications.

What is the thermal shutdown threshold for MAX15070BEUT+?

The MAX15070BEUT+ triggers thermal shutdown at +166°C junction temperature, with a 13°C hysteresis that resets the device at +153°C. This protection operates independently of supply voltage or input states and is designed to safeguard against sustained overloads, inadequate PCB copper, or ambient temperature excursions-ensuring long-term reliability in enclosed industrial enclosures or high-power density modules.
