HR1001BGS-Z

Power Supply Controllers, Monitors Overview

The HR1001BGS-Z is an enhanced LLC controller from Monolithic Power Systems, designed for resonant half-bridge converters. It operates within a supply voltage range of 13 V to 15.5 V and supports switching frequencies up to 600 kHz. The device features adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP). It utilizes a SOIC-16 surface-mount package and functions across a temperature range of -40°C to +125°C. Key electrical parameters include a static current of 1.2 mA and an operating supply current of 3 mA.

Power Supply Controllers, Monitors Feature Summary

• Adaptive Dead-Time Adjustment automatically inserts dead time between complementary gate outputs based on dV/dt detection to reduce EMI and improve efficiency.
• Capacitive Mode Protection prevents destructive switching during output short circuits or severe overloads to safeguard MOSFETs.
• Integrated 600V High-Side Gate Driver includes a bootstrap diode with high dv/dt immunity for robust operation in resonant topologies.

Power Supply Controllers, Monitors Applications

• Resonant half-bridge converter designs
• Power supplies requiring adaptive dead-time control
• Systems needing capacitive mode protection

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and reel packaging configuration as per official datasheets. Confirm that this component is the noise-immune enhanced version compatible with the original HR1001 pinout and BOM. Ensure design requirements align with the specified 13 V to 15.5 V input voltage range and SOIC-16 thermal constraints before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select the HR1001BGS-Z when enhanced noise immunity and capacitive mode protection are required compared to the standard HR1001. This variant maintains pin and BOM compatibility with the original HR1001 while adding ADTA and CMP features. It is suitable for applications prioritizing reliability under fault conditions and optimized EMI performance through automatic dead-time control.

Power Supply Controllers, Monitors Part Context

The HR1001BGS-Z belongs to the HR1001 family of enhanced LLC controllers by Monolithic Power Systems. It serves as an improved alternative to the HR1001, offering additional protection mechanisms without altering the physical footprint or basic interface. The 'B' suffix denotes the enhanced noise-immune version, while 'GS' specifies the SOIC-16 package and 'Z' typically indicates environmental compliance.

Power Supply Controllers, Monitors Replacement Considerations

The HR1001BGS-Z is functionally compatible with the HR1001GS-Z regarding pinout and BOM. Designers migrating from the standard HR1001 should verify that the enhanced protection features do not conflict with existing control loops. No other direct substitutes are confirmed in the provided documentation.
