MAX15070BEUT+T

Overview

The MAX15070BEUT+T is a low-side MOSFET gate driver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4V to 14V and features independent source and sink outputs. The device delivers a peak sink current of 7A and a peak source current of 3A, enabling efficient switching of N-channel power MOSFETs. It utilizes CMOS-like high-noise-margin logic inputs rated for voltages up to 6V. Typical rise and fall times are 36ns and 17ns, respectively. The component is housed in a compact SOT-23-6 surface-mount package and supports an operating junction temperature range from -40°C to +150°C.

Feature Summary

• Independent source and sink output configuration for optimized drive control
• High noise immunity via CMOS-like high-noise-margin logic inputs
• Robust current delivery with 7A peak sink and 3A peak source capabilities
• Wide single power-supply operation ranging from 4V to 14V

Applications

• Low-side switching in DC-DC converter topologies
• Motor control systems requiring N-channel MOSFET driving
• Power management units needing fast-switching gate drivers
• Industrial equipment utilizing isolated or non-isolated power stages

Procurement Notes

Verify the specific suffix 'BEUT' against official Analog Devices documentation to confirm pinout and electrical characteristics match project requirements. Ensure the '+T' designation aligns with tape-and-reel packaging needs. Cross-reference the manufacturer part number directly with ADI databases to avoid counterfeit components, as this series includes variants with differing input thresholds or package options that are not functionally interchangeable without schematic adjustment.

Selection Notes

Select this component when a low-side driver with high peak current capability is required for N-channel MOSFETs. The 7A sink current ensures rapid turn-off, while the 3A source current supports adequate turn-on speed. Verify that the input logic levels (2V VIL, 4.25V VIH) are compatible with the controlling microcontroller or FPGA. Consider the SOT-23-6 thermal performance if multiple devices are placed closely together on the PCB layout.

Part Context

This part belongs to the MAX15070 family of high-speed MOSFET drivers designed for efficiency and noise resilience. The BEUT variant specifically denotes the SOT-23-6 package configuration. It serves as a bridge between low-voltage logic controllers and high-power switching elements, optimizing system performance in compact power electronics designs where space and switching speed are critical constraints.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Variants such as MAX15070AAUT or MAX15070AEUT may share similar electrical profiles but differ in package type or specific suffix designations. Direct substitution requires verification of pin compatibility and exact parameter matching through official Analog Devices cross-reference tools.
