IttyBitty High-Side MOSFET Driver
Preliminary Information
General Description
The MIC5018 IttyBitty high-side MOSFET driver is de-
signed 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 N-channel MOSFETs.
In high-side configurations, the source voltage of the MOS-
FET 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.
