MIC4225 - Low-Side MOSFET Drivers

This page provides the datasheet information for the MIC4225, a member of the MIC4223 Low-Side MOSFET Drivers family.

Description

The MIC4223/MIC4224/MIC4225 are a family of a dual 4A, High-Speed, Low-side MOSFET drivers with logic-level driver enables.

The devices are fabricated on Micrel’s Bipolar/CMOS/DMOS (BCD) process and operate from a 4.5V to 18V supply voltage.

Features

  • a dedicated active-high enable input which is internally pulled high to VDD through 100kΩ, allowing the pins to be left unconnected if it is not required to disable the driver outputs. The driver inputs have been designed to protect against ground bounce and are protected to withstand -5V of voltage swing at -40mA. Driver outputs are also protected to withstand 500mA of reverse current. The MIC4223/MIC4224/MIC4225 are available in three configurations using industry standard pin out; dual invert.

MIC4223/MIC4224/MIC4225 Dual 4A, 4.5V to 18V, 15ns Switch Time, Low-Side MOSFET Drivers with Enable General Description The MIC4223/MIC4224/MIC4225 are a family of a dual 4A, High-Speed, Low-side MOSFET drivers with logic-level driver enables. The devices are fabricated on Micrel’s Bipolar/CMOS/DMOS (BCD) process and operate from a 4.5V to 18V supply voltage. The devices parallel Bipolar and CMOS output stage architecture provides high-current throughout the MOSFETs Miller Region allowing the driver to sink and source 4A of peak current from a 12V supply and quickly charge and discharge a 2000pF load capacitance in under 15ns, while allowing the outputs to swing within 0.3V of VDD and 0.16V of ground.
