MIC5015数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

MIC5014 and MIC5015 MOSFET gate drivers are designed for gate control of N-channel, enhancement-mode, power MOSFETs used as high-side or low-side switches. The MIC5014/5 can sustain an on-state output indefinitely.The MIC5014/5 operates from a 2.75 V to 30 V supply. In high-side configurations, the driver can control MOSFETs that switch loads of up to 30 V. In low-side configurations, with separate supplies, the maximum switched voltage is limited only by the MOSFET.The MIC5014/5 has a TTL compatible control input.Non-inverting and inverting configurations available:MIC5014: Non-InvertingMIC5015: Inverting.The MIC5014/5 features an internal charge pump that can sustain a gate voltage greater than the available supply voltage. The gate driver is capable of turning on a logic-level MOSFET from a 2.75 V supply or a standard MOSFET from a 5 V supply. The gate-to-source output voltage is internally limited to approximately 15 V.The MIC5014/5 is protected against automotive load dump, reversed battery, and inductive load spikes of 20 V. The drivers overvoltage shutdown feature turns off the external MOSFET at approximately 35 V to protect the load against power supply excursions.The MIC5014 is an improved pin-for-pin compatible replacement in many MIC5011 applications. The MIC5014/5 is available in plastic 8-pin DIP and 8-pin SOIC packages.
