MAX5056AASA

Overview

The MAX5056AASA is a dual low-side N-channel MOSFET gate driver IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4V to 20V and provides independent channel control with non-inverting logic inputs. The device delivers a peak output current of 4A per channel, enabling efficient switching of external power MOSFETs. Key electrical parameters include a propagation delay of 20ns and rise/fall times of 20ns when driving a 5000pF capacitive load. It is housed in an 8-SOIC-EP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Dual independent low-side driver configuration for precise control of two N-channel MOSFETs
• High-speed switching capability with 20ns propagation delay and symmetric rise/fall times
• Robust 4A peak output current drive per channel to minimize switching losses
• Non-inverting logic interface compatible with standard digital control signals

Applications

• DC-DC converter topologies requiring low-side switching
• Motor control circuits utilizing N-channel MOSFETs
• Power management systems needing fast transient response
• Industrial automation equipment with high-frequency switching requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm package integrity and pin alignment against the 8-SOIC-EP specification before integration. Review latest datasheet revisions for any design-in warnings or thermal derating guidelines applicable to your specific operating conditions.

Selection Notes

Select this component for applications requiring dual low-side drive with minimal propagation delay. Ensure the input voltage levels match the logic family used in your control circuitry. Consider thermal dissipation capabilities given the 4A peak current rating and SOIC-EP package constraints during high-duty cycle operations.

Part Context

Part of the MAX5055/MAX5056 series of dual MOSFET drivers designed for high-performance power conversion. The MAX5056AASA specifically targets low-side applications, distinguishing it from half-bridge variants. It serves as a legacy solution in established designs where its specific timing characteristics and drive strength are validated.

Replacement Considerations

Check for MAX5056AASA+T (tape and reel) if packaging format differs. Verify functional equivalence with other dual low-side drivers offering similar 4A drive and 20ns delay specs. Ensure pinout compatibility with existing PCB footprints before substitution.
