About This Product

■Summary

The HR1001L is an enhanced LLC controller that offers new Adaptive Dead Time Adjustment (ADTA) and Resonance Missing Protection (CMP) features. HR1001L is an OCP latchoff version of HR1001B. ADTA automatically inserts dead time between two complementary gate outputs by keeping the outputs off while sensing the dV/dt current at the half-bridge switching node. ADTA is characterized by ease of design, low EMI, and high efficiency. The HR1001L has built-in anti-resonance out-of-resonance protection to prevent potentially destructive out-of-resonance switching in the event of an output short circuit or severe overload. This feature protects the MOSFET during abnormal conditions and makes the converter robust. The device includes a programmable oscillator that sets both maximum and minimum switching frequencies. It starts at its maximum programmed switching frequency and decays until the control loop takes over to prevent excessive inrush current. The HR1001L enters controlled burst mode at light loads to minimize power consumption and enhance output regulation. Extensive protection features include two-level overcurrent protection (OCP), externally latched shutdown, power recovery/power failure, capacitive mode protection (CMP), and overtemperature protection (OTP).

■Features and benefits

・Two-level overcurrent protection (OCP): frequency shift and latch-off mode ・Adaptive dead time adjustment (ADTA) ・Resonance loss protection (CMP) ・50% duty cycle, variable frequency control of resonant half-bridge converter ・600V high-side gate driver with integrated bootstrap diode with high precision oscillator with high dV/dt tolerance - Operates up to 600kHz -Latch to disable input for easy protection ・Remote on/off control and power outage protection through BO ・Programmable burst mode operation at light loads ・Nonlinear soft start for monolithic output voltage rise ・Provided in SOIC-16 package
