HR1001AGS

Power Supply Controllers, Monitors Overview

The HR1001AGS-Z is an enhanced LLC controller from Monolithic Power Systems designed for resonant half-bridge converters. It features adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). The device operates with a supply voltage range of 13 V to 15.5 V and supports switching frequencies up to 600 kHz. It utilizes a SOIC-16 surface-mount package and functions within a temperature range of -40°C to +125°C. Key electrical parameters include a static current of 1.2 mA and a maximum operating frequency of 600 kHz.

Power Supply Controllers, Monitors Feature Summary

• Adaptive Dead-Time Adjustment automatically inserts dead time between complementary gate outputs to ensure zero-voltage switching and reduce EMI.
• Capacitive Mode Protection prevents potentially destructive capacitive switching during output short circuits or severe overloads.
• Integrated 600V high-side gate driver includes a bootstrap diode and offers high dv/dt noise immunity.
• Two-stage overcurrent protection provides both frequency shifting and lockout shutdown modes with adjustable duration.

Power Supply Controllers, Monitors Applications

• Resonant half-bridge converter designs
• High-efficiency AC/DC power supplies
• Offline switch-mode power applications

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (Z or P) when ordering, as it indicates the packaging format such as cut tape or reel. Confirm that the required variant matches the desired overcurrent protection behavior, as the HR1001 family includes variants with automatic recovery or lockout shutdown characteristics. Ensure compatibility with the target LLC topology before finalizing procurement specifications.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring simplified layout through integrated adaptive dead-time control. Consider the HR1001A variant if automatic recovery after overcurrent events is preferred over latch-up protection. Evaluate the need for high dv/dt immunity in noisy environments due to the integrated bootstrap diode. Verify that the 600 kHz maximum frequency aligns with the magnetic component selection for the intended power level.

Power Supply Controllers, Monitors Part Context

The HR1001 series serves as an enhanced LLC controller family within Monolithic Power Systems' portfolio. The HR1001AGS-Z specifically denotes the SOIC-16 packaged version. This component addresses efficiency and reliability challenges in resonant topologies by integrating advanced protection features directly into the control logic, reducing external component count compared to standard LLC controllers.

Power Supply Controllers, Monitors Replacement Considerations

Public documentation identifies the HR1001B and HR1001L as alternative variants within the same family. The HR1001B offers enhanced anti-noise characteristics, while the HR1001L provides a lockout version for overcurrent protection. Designers should verify pin-to-pin compatibility and protection mode differences when substituting these parts.
