Product details
Overview
The MAX15070AAUT+T from Maxim Integrated is a high-speed dual-output MOSFET driver IC with independent 7A sink (N_OUT) and 3A source (P_OUT) capability, 12ns typical propagation delay, TTL-compatible logic inputs, and operation from +4V to +14V supply. It enables precise control of power MOSFET turn-on/turn-off timing in high-frequency DC-DC converters.
For engineers reviewing the MAX15070AAUT+T datasheet, MAX15070AAUT+T pinout, MAX15070AAUT+T application, or MAX15070AAUT+T equivalent, key selection criteria include matched input delays (<500ps), shoot-through prevention logic, thermal shutdown at 166°C, and SOT23-6 package compatibility with high di/dt gate-drive layouts.
Technical Context
The MAX15070AAUT+T implements complementary open-drain outputs: an n-channel sink (N_OUT) optimized for fast MOSFET turn-off and a p-channel source (P_OUT) for controlled turn-on. Its internal break-before-make control prevents shoot-through during state transitions.
Input logic is TTL-level (VIH = 2.0V, VIL = 0.8V), with ±16V input spike tolerance regardless of V+ voltage, and low 10pF input capacitance to minimize loading. Undervoltage lockout activates below 3.45V (200mV hysteresis) to force safe output states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Sink Current | 7A at N_OUT - enables rapid discharge of large MOSFET gate capacitances (e.g., >10nF) for sub-20ns fall times |
| Peak Source Current | 3A at P_OUT - supports fast charging of gate capacitance without external boost circuitry |
| Propagation Delay | 12ns typical - ensures tight timing alignment between IN+ and IN− paths for synchronous switching control |
| Supply Voltage Range | +4V to +14V - compatible with 5V, 12V, and wide-input industrial SMPS rails without level-shifting |
| Input Logic Type | TTL - interoperable with standard microcontroller GPIOs, FPGA I/O banks, and PWM controllers without interface buffers |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and high-density power modules |
| Thermal Shutdown | 166°C junction temperature - protects against latch-up or bond-wire failure during sustained overload or poor heatsinking |
Pinout & Package
Package: 6-pin SOT23 (U6+1A outline, JEDEC MO-178AA), footprint land pattern 90-0175, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting logic input | Active-high enable path; connect to V+ if unused; TTL threshold (2.0V VIH) allows direct MCU interfacing |
| 2 - GND | Power and signal reference ground | Low-inductance return path for 7A sink current; must be tied to solid ground plane to prevent ringing |
| 3 - IN− | Inverting logic input | Active-low control; complements IN+ for push-pull or half-bridge gate drive; 0.8V VIL ensures noise immunity |
| 4 - N_OUT | n-Channel open-drain sink output | Drives MOSFET gate low; 0.32Ω typical RDS(ON) at +12V enables <10ns fall time into 5nF load |
| 5 - P_OUT | p-Channel open-drain source output | Drives MOSFET gate high; 1.2Ω typical RDS(ON) at +12V supports controlled rise time with series gate resistor |
| 6 - V+ | Positive power supply input | Accepts +4V to +14V; requires local 1µF ceramic bypass to GND; peak supply current up to 3A during switching |
Key Features
| Feature | Design Value |
|---|---|
| Independent source/sink outputs | Enables separate optimization of MOSFET turn-on (via P_OUT) and turn-off (via N_OUT) speeds using discrete gate resistors |
| Matched propagation delays | <500ps mismatch between IN+ and IN− paths ensures symmetrical timing in dual-input configurations |
| Shoot-through prevention logic | Internal break-before-make control guarantees dead-time insertion, eliminating cross-conduction in half-bridge topologies |
| High-voltage input protection | Withstands +16V transients on IN+/IN− pins independent of V+, simplifying ESD protection in noisy environments |
| Thermal shutdown with hysteresis | 166°C trip point with 13°C hysteresis prevents thermal oscillation during intermittent overload conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15070BAUT+ | HNM (CMOS-like) input thresholds (VIH = 4.25V, VIL = 2.0V); otherwise identical pinout, specs, and package | Better noise immunity in high-EMI automotive environments; requires higher logic-high voltage than TTL | Select when interfacing with 3.3V or 5V CMOS controllers where TTL thresholds risk marginal switching |
| LM5113SDX/NOPB | Single 5A sink/3A source output; no independent P_OUT/N_OUT; 15ns propagation delay; 8-pin WSON package | Lacks complementary output flexibility; requires external dead-time generation for half-bridge use | Choose when board space permits larger package and system-level dead-time control is already implemented |
Compared with MAX15070BAUT+, the MAX15070AAUT+T offers lower VIH for legacy 5V TTL systems but less noise margin; versus LM5113SDX/NOPB, it delivers true independent turn-on/turn-off control in a smaller SOT23 footprint-critical for compact multi-phase designs.

FAQ
What is the maximum capacitive load the MAX15070AAUT+T can drive while maintaining specified rise/fall times?
The MAX15070AAUT+T is characterized for CL = 1nF to 10nF loads. At CL = 5nF and V+ = +12V, typical rise time is 22ns and fall time is 11ns. Driving >10nF loads increases timing skew and may exceed thermal limits unless gate resistors and PCB layout minimize loop inductance. For 10nF+ loads, parallel 10µF bulk capacitance near V+ is recommended per the datasheet.
Does the MAX15070AAUT+T support half-bridge configurations without external logic?
Yes - the MAX15070AAUT+T's complementary P_OUT and N_OUT outputs, combined with internal break-before-make control, allow direct connection to high-side and low-side MOSFET gates in half-bridge topologies. No external dead-time circuitry is needed, as the IC enforces minimum 2ns non-overlap between outputs per the truth table and functional diagram.
How does the undervoltage lockout (UVLO) function affect the outputs of the MAX15070AAUT+T during startup?
When V+ falls below 3.45V (typical UVLO threshold), the MAX15070AAUT+T forces N_OUT ON and P_OUT OFF - pulling the driven MOSFET gate low for safe default state. This occurs independently of IN+ and IN− logic levels. The 200mV hysteresis prevents oscillation during slow-rising supply rails, and the 2µs falling delay rejects narrow negative transients.
Can unused inputs (IN+ or IN−) be left floating on the MAX15070AAUT+T?
No - unused inputs must not be left floating. Per the Pin Description, IN+ should be tied to V+ and IN− to GND when not actively used. Floating inputs risk undefined output states, increased susceptibility to EMI, and potential shoot-through due to noise-induced switching. Alternatively, an unused input may serve as an on/off control signal per Table 1.
What thermal considerations apply to the MAX15070AAUT+T in continuous 7A sink operation?
At 7A peak sink current, power dissipation depends on RDS(ON) (0.32Ω typ), duty cycle, and frequency. With 50% duty and 1MHz switching into 5nF, junction temperature rise can exceed 80°C/W × 150mW ≈ 12°C above ambient. The MAX15070AAUT+T's 166°C thermal shutdown and 115°C/W θJA (four-layer board) require adequate copper area and airflow for sustained high-current operation above +85°C ambient.
