MIC5011数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

The MIC5011 is the \"minimum parts count\" member of the MIC501X gate driver family. These ICs are designed to drive the gate of an N-channel power MOSFET above the supply rail in high-side power switch applications. The 8-pin MIC5011 is extremely easy to use, requiring only a power FET and nominal supply decoupling to implement either a high- or low-side switch.The MIC5011 charges a 1 nF load in 60 µs typical with no external components. Faster switching is achieved by adding two 1 nF charge pump capacitors. Operation down to 4.75 V allows the MIC5011 to drive standard MOSFETs in 5 V low-side applications by boosting the gate voltage above the logic supply. In addition, multiple paralleled MOSFETs can be driven by a single MIC5011 for ultra-high current applications.Other members of the driver family include the MIC5013 protected 8-pin driver.For new designs, recommends the pin-compatible MIC5014 MOSFET gate driver.
