MIC4125 - Micrel Semiconductor

MIC4125 Dual 3A-Peak Low-Side MOSFET Driver

The MIC4123/4124/4125 family are highly reliable BiCMOS/DMOS buffer/driver/MOSFET drivers. They are higher output current versions of the MIC4126/4127/4128, which are improved versions of the MIC4426/4427/4428. All three families are pin-compatible. The MIC4123/4124/4125 drivers are capable of giving reliable service in more demanding electrical environments.
