MIC5014/5  
High- or Low-Side MOSFET Drivers  
Features  
General Description  
• 2.75V to 30V Operation  
The MIC5014 and MIC5015 MOSFET drivers are  
designed  
for  
gate  
control  
of  
N-channel,  
• 100 μA Maximum Supply Current (5V Supply)  
• 15 μA Typical Off-State Current  
• Internal Charge Pump  
enhancement-mode, power MOSFETs used as  
high-side or low-side switches. The MIC5014/5 can  
sustain an on-state output indefinitely.  
• TTL-Compatible Input  
The MIC5014/5 operate from a 2.75V to 30V supply. In  
high-side 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.  
• Withstands 60V Transient (Load Dump)  
• Reverse Battery Protection to –20V  
• Inductive Spike Protection to –20V  
• Overvoltage Shutdown at 35V  
• Internal 15V Gate Protection  
• Minimum External Parts  
The MIC5014/5 have a TTL-compatible control input.  
The MIC5014 is non-inverting, while the MIC5015 is  
inverting.  
• Operates in High-Side or Low-Side  
Configurations  
The MIC5014/5 feature 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.  
• 1 µA Control Input Pull-Off  
• Inverting and Non-Inverting Versions  
Applications  
• Automotive Electrical Load Control  
• Battery-Powered Computer Power Management  
• Lamp Control  
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.  
• Heater Control  
• Motor Control  
• Power Bus Switching  
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.
