IttyBitty ? High-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.
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

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.
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.
