HR1001LGS-Z

Power Supply Controllers, Monitors Overview

The HR1001LGS-Z is an enhanced LLC controller from Monolithic Power Systems, packaged in a 16-lead SOIC. It operates within an input voltage range of 13 V to 15.5 V and supports a switching frequency up to 600 kHz. The device features two outputs and includes adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). It functions reliably across a temperature range of -40°C to +125°C with a 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 programmable oscillator allows setting maximum and minimum switching frequencies for soft-start control.

Power Supply Controllers, Monitors Applications

• Resonant half-bridge converter designs
• High-efficiency power supply systems requiring adaptive timing
• Applications needing robust protection against capacitive mode faults

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix Z indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Check current lifecycle status as NRND may impact long-term availability. Ensure design-in compatibility with existing BOM requirements before procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring adaptive dead-time control to optimize performance. Consider the integrated capacitive mode protection for enhanced reliability under fault conditions. Verify that the SOIC-16 package fits the thermal and spatial constraints of the target application.

Power Supply Controllers, Monitors Part Context

This part belongs to the HR1001 series of enhanced LLC controllers. It serves as an evolution of previous models by adding adaptive dead-time and capacitive mode protection features while maintaining pin and BOM compatibility with earlier versions like the HR1001B.

Power Supply Controllers, Monitors Replacement Considerations

HR1001BGS-Z is a compatible alternative within the same family offering similar functionality with enhanced noise immunity characteristics.
