HR1001AGS-Z

Power Supply Controllers, Monitors Overview

The HR1001AGS-Z is an enhanced LLC controller from Monolithic Power Systems, packaged in a 16-SOIC. It operates with an input voltage range of 13 V to 15.5 V and features a switching frequency up to 600 kHz. The device draws a static current of 1.2 mA and a working supply current of 3 mA. It supports two outputs and functions within a temperature range of -40°C to +125°C.

Power Supply Controllers, Monitors Feature Summary

• Adaptive dead-time adjustment automatically inserts dead time between complementary gate drive signals to ensure driver signals remain off during half-bridge node dv/dt detection, reducing EMI and improving efficiency.
• Capacitive mode protection prevents potentially destructive capacitive mode switching during output short circuits or severe overloads, safeguarding MOSFETs and ensuring converter reliability.
• Programmable oscillator sets maximum and minimum switching frequencies, starting at maximum upon startup to prevent excessive inrush current before the control loop takes over.

Power Supply Controllers, Monitors Applications

• Resonant half-bridge converters
• Flyback converters
• Forward converters

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix Z for lead-free compliance against RoHS standards. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Check moisture sensitivity level (MSL 2) handling procedures if storage conditions exceed specified limits. Ensure the 13 V to 15.5 V supply range aligns with your system's operational voltage.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring adaptive dead-time control to optimize efficiency and reduce electromagnetic interference. It is suitable for applications needing capacitive mode protection to enhance safety during fault conditions. Consider the 600 kHz maximum frequency for compact magnetic component sizing. Verify compatibility with half-bridge topologies requiring precise timing control.

Power Supply Controllers, Monitors Part Context

The HR1001AGS-Z belongs to the HR1001 series of enhanced LLC controllers by Monolithic Power Systems. It shares core functionalities with the HR1001BGS-Z but differs in overcurrent protection behavior, offering automatic recovery compared to other variants. This series targets high-efficiency power conversion solutions.

Power Supply Controllers, Monitors Replacement Considerations

HR1001BGS-Z is a related variant within the same family, differing primarily in overcurrent protection response mechanisms.
