HR1001LGS-P

Power Supply Controllers, Monitors Overview

The HR1001LGS-P is an enhanced LLC controller from Monolithic Power Systems, packaged in a SOIC-16 surface-mount format. It operates with an input voltage range of 13 V to 15.5 V and features a maximum switching frequency of 600 kHz. The device provides two outputs and maintains a static current of 1.2 mA with a working supply current of 3 mA. It supports an operating temperature range from -40 C to +125 C and includes humidity sensitivity characteristics.

Power Supply Controllers, Monitors Feature Summary

• Adaptive Dead-Time Adjustment (ADTA) automatically inserts dead time between complementary gate outputs based on half-bridge node dV/dt detection to reduce EMI and improve efficiency.
• Capacitive Mode Protection (CMP) prevents potentially destructive capacitive mode switching during output short circuits or severe overloads to protect MOSFETs.
• Programmable oscillator sets maximum and minimum switching frequencies, starting at maximum frequency during startup to limit inrush current before the control loop takes over.

Power Supply Controllers, Monitors Applications

• Resonant half-bridge converters requiring adaptive dead-time control
• Power supplies needing protection against capacitive mode switching under fault conditions
• Applications requiring controlled burst mode operation for light-load efficiency

Power Supply Controllers, Monitors Procurement Notes

Verify that the specific suffix P indicates the correct tape and reel packaging configuration required for your assembly line. Confirm that the component meets RoHS compliance standards if mandated by your project specifications. Ensure handling procedures account for moisture sensitivity levels as indicated in the datasheet to prevent damage during soldering processes.

Power Supply Controllers, Monitors Selection Notes

Select this model when adaptive dead-time control and capacitive mode protection are critical for system reliability and efficiency. It serves as an OCP locked version variant within the HR1001 family, offering specific protection profiles compared to standard versions. Consider the SOIC-16 package constraints and thermal requirements for high-temperature operation up to 125 C.

Power Supply Controllers, Monitors Part Context

The HR1001LGS-P belongs to the HR1001 series of enhanced LLC controllers designed for resonant converter topologies. It builds upon previous iterations like the HR1001B by incorporating advanced features such as ADTA and CMP. This component is part of MPS's portfolio aimed at simplifying design while enhancing performance in power management applications.

Power Supply Controllers, Monitors Replacement Considerations

HR1001LGS-Z is a documented alternative within the same product family sharing identical functional specifications and package type. Designers should verify pinout compatibility and parameter equivalence before substitution.
