The MIC4423BM-TR is an IC (Integrated Circuit) component manufactured by Microchip Technology Inc. It is specifically designed for driving capacitive and inductive loads in various applications such as motor control, solenoid control, and power converters. This IC is part of the MIC442x family of gate drivers and offers several key features that make it a popular choice for these applications.
One notable feature of the MIC4423BM-TR is its ability to provide high peak output currents while operating at a low input supply voltage. With a wide input supply range of 4.5V to 18V, it efficiently drives power MOSFETs and IGBTs (insulated-gate bipolar transistors) by delivering peak output currents up to 9A. This enables it to handle demanding load requirements effortlessly.
The MIC4423BM-TR offers robust protection mechanisms to ensure reliable and safe operation. It incorporates an undervoltage lockout (UVLO) feature that prevents the device from operating if the input voltage falls below a specified threshold. This protection prevents the IC from malfunctioning or damaging the load in scenarios where the supply voltage is inadequate.
Another essential feature of the MIC4423BM-TR is its precise output control. It uses TTL (Transistor-Transistor Logic) or CMOS (Complementary Metal-Oxide-Semiconductor) input signals to drive the output stage
