MIC4428BM Description

Short technical summary and product information.

The Micrel Inc. MIC4428BM is a highly reliable dual low-side MOSFET driver fabricated on a BiCMOS/DMOS process. It translates TTL or CMOS input logic levels to output voltage levels that swing within 25mV of the positive supply or ground. This driver offers a peak output current of 1.5A and operates over a voltage range of 4.5V to 18V.

 

Key electrical specifications include a typical output impedance of 7Ω, a typical delay time of less than 40ns, and the ability to switch 1000pF in 25ns. It also features latch-up protection to greater than 500mA reverse current and noise spike tolerance on ground pins.

 

The MIC4428BM is available in an inverting and non-inverting configuration and comes in an 8-lead SOIC surface mount package. Its design makes it suitable for driving power MOSFETs, clock lines, coaxial cables, and piezoelectric transducers.
