MIC5014BM Datasheet

PMIC - MOSFET, Bridge Drivers - External Switch


MIC5014BM 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 MIC5014BM 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 –20V. The driver’s overvoltage shutdown feature turns off the external MOSFET at approximately 35V to protect the load against power supply excursions.The MIC5014BM 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.
