Description

As a single-channel high-speed low-side grid driver with the peak sourcing current of 4A and the peak sinking current of 8A,SL27511 can drive MOSFET,IGBT and emerging broad-band gap power devices efficiently and safely. With characteristics of low propagation delay and compact SOT-23,it can achieve the MOSFET switching frequency of hundreds of kHz.The chip is applicable to synchronous rectification driving of servers and communication power supply.In this condition,the dead time of the synchronous tube MOSFET leads to direct influence on efficiency of the converter. The 4.5V to 20V wide ranges VDD supply voltage can drive MOSFET or GaN power devices effectively. The integrated UVLO protective function can ensure the output low level in abnormal conditions. The -5V to 24V independent input pin voltage ranges can ensure stable working in condition ofover-shoot caused by stray inductance. The voltage threshold value of the input pin is compatible to the TTL level input.
