MIC5018

High-Side MOSFET Driver

Features

General Description

• +2.7V to +9V Operation

The MIC5018 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.

• 150 μA Typical Supply Current at 5V Supply

• ≤1 μA Typical Standby (Off) Current

• Charge Pump for High-Side Low-Voltage

Applications

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.

• Internal Zener Diode Gate-to-Ground MOSFET

Protection

• Operates in Low- and High-Side Configurations

• TTL Compatible Input

• 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

Package Type

MIC5018

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.

SOT-143 (M4)

The MIC5018 is available in the SOT-143 package and

is rated for –40°C to +85°C ambient temperature

range.
