RTQ6056GF

Current Regulation/Management Overview

The RTQ6056GF is a high-accuracy current-sense monitor manufactured by Richtek USA Inc. It supports bidirectional current sensing for both high-side and low-side configurations. The device features an integrated 16-bit ADC to convert voltage drops across a shunt resistor into digital values for load current and power. It operates with a supply voltage range of 2.7 V to 5.5 V and monitors bus voltages from 0 V to 36 V. Key electrical specifications include a maximum gain error of 0.12% and a maximum offset voltage of 10 µV. The component utilizes I²C and SMBus interfaces for communication.

• Bidirectional current sensing capability supporting both high-side and low-side measurement topologies
• Integrated 16-bit analog-to-digital converter for precise conversion of current and power data
• Programmable calibration, adjustable conversion time, and averaging functions for design flexibility
• Open-drain alert output providing warnings for overcurrent, overvoltage, and overpower conditions

Current Regulation/Management Applications

• Servers, storage, and network equipment
• Portable and battery-powered systems
• Point-of-load (POL) modules
• Laptops
• High-end digital televisions

Current Regulation/Management Procurement Notes

Verify the specific suffix GF against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the operating temperature range meets the environmental constraints of the target application.

Current Regulation/Management Selection Notes

Select this component when high precision is required for monitoring both current and power in bidirectional applications. The low offset voltage and gain error make it suitable for sensitive measurements. Consider the MSOP-10 package size for space-constrained designs. Verify that the I²C/SMBus interface aligns with the host controller capabilities and that the alert thresholds can be programmed to suit specific system protection needs.
