General Description

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.

Features

• +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

• ESD protected

Applications

• Battery conservation

• Power bus switching

• Solenoid and motion control

• Lamp control
