MIC5014 and MIC5015 MOSFET 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 2.75V to 30V supply. In highside configurations, the driver can control MOSFETs that switch loads of up to 30V. 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. The MIC5014 is noninverting while the MIC5015 is inverting. The MIC5014/5 features an internal charge pump that can sustain a gate voltage greater than the available supply voltage. The driver is capable of turning on a logic-level MOSFET from a 2.75V supply or a standard MOSFET from a 5V supply. The gate-to-source output voltage is internally limited to approximately 15V.
The MIC5014/5 is protected against automotive load dump, reversed battery, and inductive load spikes of â€“20V. The driverâ€™s overvoltage shutdown feature turns off the external MOSFET at approximately 35V 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 pacakges.
