Introduction

AI Translation

LF21814N is a high-voltage, high-speed power MOSFET/IGBT high- and low-side gate driver series IC featuring two independent transmission channels with logic ground isolated from power ground, effectively reducing power stage noise interference on logic circuits. The device integrates protection circuits including high- and low-side UVLO and overvoltage clamp circuits, with high-current pulse output capability. Logic input levels are compatible with CMOS or LSTTL logic outputs as low as 3.3V, with a maximum output current of 4A and a maximum floating channel operating voltage of 700V. Suitable for driving N-channel high-voltage power MOSFETs/IGBTs and similar devices. LF21814N is available in a SOP-14 package and operates over a temperature range of -40°C to 125°C.
