Description

The SL27517 is a single-channel 4A high-speed low-side gate driver that efficiently and safely drives MOSFETs, IGBTs, and emerging wide-bandgap power devices. With characteristics of low propagation delay and compact SOT-23, it can achieve the MOSFET switching frequency of hundreds ofkHz.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 V_DD 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.
