This datasheet details the MIC4426/4427/4428 family of dual low-side MOSFET drivers, featuring 1.5A peak output current and latch-up protection for driving…
The MIC4426/4427/4428 family consists of highly-reliable dual low-side MOSFET drivers fabricated on a BiCMOS/DMOS process. These devices translate TTL or CMOS input logic levels to output voltage levels that swing within 25mV of the positive supply or ground, offering superior performance compared to comparable bipolar devices. The family is available in three configurations: dual inverting (MIC4426), dual noninverting (MIC4427), and one inverting plus one noninverting (MIC4428).
| Peak Output Current | 1.5 A |
|---|---|
| Operating Supply Voltage | +4.5V to +18V |
| Latch-up Protection | >500 mA reverse current |
| Switching Time (Rise) | 18 ns (Typ) |
| Switching Time (Fall) | 15 ns (Typ) |
| Output Offset | 25mV max |
| Input Protection | -5V |
Yes, they are pin-compatible replacements for the MIC426/427/428 and MIC1426/1427/1428.
The drivers can withstand up to 500mA of reverse current (either polarity) without latching.
