MAX627CSA+

Overview

The MAX627CSA+ is a dual low-side gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 18V and supports CMOS and TTL logic inputs. The device features independent non-inverting channels with peak output currents of 2A for both sourcing and sinking. Typical rise and fall times are 25ns and 20ns, respectively. It is housed in an 8-SOIC package (0.154" width) and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High peak drive capability supporting 2A source and sink currents
• Fast switching performance with typical transition times under 25ns
• Compatible with standard CMOS and TTL input logic levels

Applications

• Low-side power switching applications
• MOSFET gate driving circuits
• Power management IC subsystems

Procurement Notes

Verify the specific suffix CSA+ indicates surface mount SOIC packaging and lead-free compliance. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the operating temperature range meets system requirements of 0°C to +70°C. Check for RoHS3 status if environmental compliance is mandatory for the target assembly process.

Selection Notes

Select this component when dual independent low-side drive is required with moderate speed and high current capability. The 8-SOIC package suits surface mount assembly processes. Verify that the load capacitance and switching frequency requirements align with the 25ns/20ns transition times. Ensure the input logic voltage levels match the specified 0.8V and 2.4V thresholds for reliable operation.

Part Context

This part belongs to the MAX627 series of dual low-side gate drivers. It shares functional similarities with other members like the MAX627MJA and MAX627ESA+, differing primarily in packaging and qualification grades. The series is categorized under PMIC Gate Drivers within the broader power management integrated circuit portfolio.
