UCD7201PWP

Gate Driver Overview

The UCD7201PWP is a digital control compatible dual low-side MOSFET driver manufactured by Texas Instruments. It features two independent drivers capable of sourcing and sinking 4 A of peak current. The device integrates a programmable common current sense amplifier for synchronous buck converter applications. It operates within a supply voltage range of 4.5 V to 15 V and supports CMOS and TTL logic inputs. The component is housed in a 14-HTSSOP package with exposed pad, designed for surface mount installation.

Gate Driver Feature Summary

• Dual low-side gate drivers with ±4 A output capability
• Integrated programmable common current sense amplifier
• Compatible with standard digital control logic families
• Designed for synchronous buck converter topologies

Gate Driver Applications

• Synchronous buck converters
• Digital power supply designs
• Motor control systems requiring low-side switching
• General purpose DC-DC conversion circuits

Gate Driver Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance when sourcing. Confirm the HTSSOP-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your system's thermal constraints. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Gate Driver Selection Notes

Select this component when a dual low-side driver with integrated current sensing is required. It is suitable for applications needing precise current monitoring without external amplifiers. Consider the 14-pin HTSSOP package for space-constrained layouts. Evaluate the 4.5 V to 15 V supply range against your system's available voltage rails.

Gate Driver Part Context

The UCD7201 belongs to Texas Instruments' UCD7xxx series of gate drivers. This family focuses on providing integrated solutions for synchronous rectification in power management applications. The PWP variant specifically denotes the 14-lead HTSSOP package configuration. It complements other single-channel drivers like the UCD7100 in multi-phase designs.

Gate Driver Replacement Considerations

UCD7201PWPRG4 is a direct equivalent with reel packaging. UCD7201PWPR offers the same functionality in tape-and-reel format. Verify that any substitute maintains the ±4 A drive current and current sense amplifier specifications.
