Results forHL9611

HL9611 is 100-V three half-bridge gate drivers, capable of driving high-side and low-side N-channel power MOSFETs. The HL9611 generates the correct gate drive voltages using an integrated bootstrap diode and external capacitor for the high-side MOSFETs. The Gate Drive architecture supports peak up to 1.0-A source and 1.8-A sink currents. Built-in dead time protection and shoot-through protection prevent damage to the half-bridge. The UVLO circuit prevent malfunction when VCC and VBS are lower than the specified threshold voltage. A novel high-voltage BCD process and common-mode noise canceling technique provide stable operation of high-side drivers under high dv/dt noise conditions while achieving excellent negative transient voltage tolerance. An enable pin (EN) is included so that standby mode may be used to set the chip into a low quiescent current state to realize long battery lifetime. Built-in 12V LDO control circuit and 5.0V LDO for MCU power supply, simplifying the power supply system.
