HR1001BGS

Power Supply Controllers, Monitors Overview

The HR1001BGS-Z is an enhanced LLC controller from Monolithic Power Systems, packaged in a 16-SOIC. It operates with a supply voltage range of 13 V to 15.5 V and features a maximum switching frequency of 600 kHz. The device supports two outputs and includes adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). Operating temperatures span from -40°C to +125°C, with a typical static current of 1.2 mA.

Power Supply Controllers, Monitors Feature Summary

• Adaptive dead-time adjustment automatically inserts dead time between complementary gate outputs to reduce EMI and improve efficiency.
• Capacitive mode protection prevents destructive switching during output short circuits or severe overloads.
• Integrated high-side gate driver with bootstrap diode supports up to 600V with high dv/dt immunity.
• Programmable oscillator allows setting maximum and minimum switching frequencies for soft-start control.

Power Supply Controllers, Monitors Applications

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

Power Supply Controllers, Monitors Procurement Notes

Verify the suffix Z indicates RoHS compliance and tape-and-reel packaging. Confirm the SOIC-16 package dimensions match your PCB footprint. Check moisture sensitivity level requirements for your assembly process. Ensure the 13V to 15.5V supply range aligns with your system design.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring enhanced noise immunity compared to the standard HR1001. Consider the ADTA feature if minimizing electromagnetic interference is critical. Verify compatibility with existing BOMs if upgrading from HR1001. Evaluate the 600kHz frequency limit against your transformer design constraints.

Power Supply Controllers, Monitors Part Context

This part belongs to the HR1001B series, which serves as an improved version of the HR1001 with added robustness features. It maintains pin and BOM compatibility with the original HR1001 while introducing new protection mechanisms. The series targets high-efficiency power conversion applications requiring reliable operation under varying load conditions.

Power Supply Controllers, Monitors Replacement Considerations

HR1001BGS-P is a compatible alternative within the same series. HR1001LGS-Z offers similar features but includes OCP locking functionality. Standard HR1001 variants are pin-compatible but lack the enhanced ADTA and CMP features found in the B-series.
