MIC5018  
IttyBittyHigh-Side MOSFET Driver  
General Description  
Features  
The MIC5018 IttyBitty™ high-side MOSFET driver is  
designed to switch an N-channel enhancement-type  
MOSFET from a TTL compatible control signal in high- or  
low-side switch applications. This driver features the tiny  
4-lead SOT-143 package.  
+2.7V to +9V operation  
150µA typical supply current at 5V supply  
1µA typical standby (off) current  
Charge pump for high-side low-voltage applications  
Internal zener diode gate-to-ground MOSFET protection  
Operates in low- and high-side configurations  
TTL compatible input  
The MIC5018 is powered from a +2.7V to +9V supply  
and features extremely low off-state supply current.  
An internal charge pump drives the gate output higher  
than the driver supply voltage and can sustain the gate  
voltage indefinitely. An internal zener diode limits the  
gate-to-source voltage to a safe level for standard  
N-channel MOSFETs.  
ESD protected  
Applications  
In high-side configurations, the source voltage of the  
MOSFET approaches the supply voltage when switched  
on. To keep the MOSFET turned on, the MIC5018’s output  
drives the MOSFET gate voltage higher than the supply  
voltage. In a typical high-side configuration, the driver is  
powered from the load supply voltage. Under some  
conditions, the MIC5018 and MOSFET can switch a load  
voltage that is slightly higher than the driver supply  
voltage.  
Battery conservation  
Power bus switching  
Solenoid and motion control  
Lamp control  
In a low-side configuration, the driver can control a  
MOSFET that switches any voltage up to the rating of the  
MOSFET. The gate output voltage is higher than the  
typical 3.3V or 5V logic supply and can fully enhance a  
standard MOSFET.  
The MIC5018 is available in the SOT-143 package and is  
rated for –40°C to +85°C ambient temperature range.
