MAX15019BASA+T

Overview

The MAX15019BASA+T is a high-speed half-bridge gate driver IC designed for driving N-channel MOSFETs. It integrates two independent drivers supporting both inverting and non-inverting logic inputs. The device operates with a supply voltage range of 8V to 12.6V and delivers peak output currents of 3A for both sourcing and sinking. It features a maximum high-side bootstrap voltage rating of 125V, ensuring robust performance in high-voltage applications. Typical rise and fall times are 50ns and 40ns respectively, facilitating efficient switching. The component is housed in an 8-SOIC package with an exposed pad (EP) for thermal management.

Feature Summary

• Integrates dual independent gate drivers optimized for high-side and low-side N-channel MOSFETs in half-bridge topologies
• Supports both inverting and non-inverting input configurations for flexible control logic integration
• Provides high-speed switching capabilities with typical rise and fall times of 50ns and 40ns
• Features a robust 125V maximum high-side bootstrap voltage rating for high-voltage operation

Applications

• High-side and low-side N-channel MOSFET gate driving in half-bridge circuits
• Motor control systems requiring precise and fast switching signals
• Power conversion topologies utilizing half-bridge architectures

Procurement Notes

Verify the specific suffix 'BASA+T' to ensure correct packaging and pinout compatibility. Confirm that the 8-SOIC-EP package footprint matches your PCB design, particularly the exposed pad thermal requirements. Check current lifecycle status as availability may be restricted or subject to limited stock conditions depending on the distributor.

Selection Notes

Select this component when a dual-channel half-bridge driver with high-speed performance is required. Ensure the application voltage does not exceed the 125V bootstrap limit. Verify that the 3A peak drive current meets the MOSFET gate charge requirements at the desired switching frequency. Consider the 8-SOIC-EP package for adequate thermal dissipation in dense layouts.

Part Context

This part belongs to the Maxim Integrated half-bridge gate driver family, specifically designed for power management and motor control applications. It complements other drivers in the series by offering integrated inverting and non-inverting outputs in a compact surface-mount package. The device is manufactured by Analog Devices Inc./Maxim Integrated, leveraging established expertise in high-performance analog and mixed-signal semiconductors.

Replacement Considerations

The MAX15018AASA+ is a related half-bridge driver from the same manufacturer but lacks the combined inverting/non-inverting input flexibility of the MAX15019. Verify pin-to-pin compatibility and electrical specifications before substitution. No direct public substitute part numbers are confirmed for this specific variant.
