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.
