MAX626CSA+

Overview

The MAX626CSA+ is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4.5 V to 18 V and supports CMOS and TTL logic inputs. The device provides independent non-inverting outputs with peak currents of 2 A for both sourcing and sinking. Key electrical parameters include rise and fall times of 20 ns, an output voltage saturation of 25 mV, and a quiescent supply current of 12 mA. It is housed in an 8-SOIC package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Dual independent low-side channel configuration for driving N-channel and P-channel MOSFETs
• High peak output current capability of 2 A for efficient switching performance
• Fast propagation characteristics with 20 ns rise and fall times
• Compatible with standard CMOS and TTL logic input levels

Applications

• Low-side switching control in DC-DC converter topologies
• Gate drive circuits for power MOSFETs in motor control systems
• General-purpose high-current switching applications requiring fast transition times

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot codes against official datasheets. Ensure storage conditions adhere to moisture sensitivity level requirements for SOIC packages. Cross-reference ordering information with current availability data from verified suppliers to prevent counterfeit risks.

Selection Notes

Select this component when dual low-side drive is required with moderate speed and high current capacity. Evaluate thermal dissipation capabilities given the 450 mW power dissipation rating in the SOIC-8 package. Consider input logic compatibility with the controlling microcontroller or FPGA. Assess operating voltage alignment with the target MOSFET gate threshold requirements within the 4.5 V to 18 V range.

Part Context

This part belongs to the MAX626 series of dual low-side gate drivers designed for general-purpose power switching applications. It complements other Maxim Integrated solutions by providing a cost-effective, compact alternative for driving power stages where high-side or bootstrap drive is not necessary. The series emphasizes reliability and ease of integration into standard PCB layouts using surface-mount technology.
