SL27511-正面

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.

Characteristics

● 6-pin SOT-23 packaging.

● 4A peak sourcing current and 8A peak sinking current.

● Wide-range VDD power supply as high as 24V.

● VDD under-voltage protection,4.5V to 20V recommended working voltage.

● Dual-input design with both configuration of positive input and that of inverted input. The not used input pin can be used for enabling or discnabling control.

● Negative voltage input as low as -5V.

● Compatible to TTL and CMOS input level.

● Low propagation delay (with the typical value lower than 20ns).

● Output low level during input floating.

● Separated output,and connecting speed and disconnecting speed can be regulated separately.

● Working temperature ranges of-40℃tol25℃.

Applications

● Switching power supply

● Motor control

● AC/DC and DC/DC converter

● Server and rectifier for communication equipment

● EV/HEV inverter and DC/DC convertor

● PV voltage rise and inverter

● UPS

● Applied to emerging broad-band gap power element driver
