Microchip Technology, Inc. PMIC - PMIC - Gate Drivers - MIC4423BWM MIC4423BWM

The MIC4423BWM is a dual inverting low-side gate driver from Quarktwin Technology Ltd., designed for driving power MOSFETs and other loads requiring high peak currents and fast switching times. It operates within a supply voltage range of 4.5V to 18V and can deliver a peak output current of 3A. The device features a robust BiCMOS/DMOS construction that minimizes power dissipation and provides rail-to-rail voltage swings. It is latch-up protected against reverse currents exceeding 500mA and can withstand noise spikes of up to 5V on the ground pin. The MIC4423BWM is capable of driving capacitive loads of up to 1800pF with a rise and fall time of approximately 25ns and 35ns, respectively. It has a low output impedance of 3.5Oc and maintains consistent delay times regardless of supply voltage changes. The device is suitable for a variety of applications, including heavily loaded clock lines and piezoelectric transducers, while ensuring that total power dissipation remains within the package limits. The operating temperature range for this part is -40¬8C to +85¬8C, making it suitable for a wide range of environments.
