MIC4452VM

Overview

The MIC4452VM is a low-side MOSFET gate driver manufactured by Microchip Technology. It utilizes a Bipolar/CMOS/DMOS process to deliver a 12A peak output current. The device operates within a supply voltage range of 4.5V to 18V and features non-inverting logic configuration. Key electrical parameters include a rise time and fall time of 25ns each, with a propagation delay of 35ns. It is housed in an 8-pin SOIC package (3.90mm width) and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-speed switching performance with 25ns rise and fall times for efficient MOSFET control.
• Provides robust 12A peak drive current capability to handle demanding capacitive loads.
• Integrates functions previously requiring multiple discrete components to simplify design and reduce PCB area.
• Features non-inverting input logic for straightforward interface with standard control signals.

Applications

• High-frequency DC-DC converters
• Motor control systems
• Power supply designs requiring fast switching

Procurement Notes

Verify the specific suffix 'VM' corresponds to the tube packaging variant rather than the 'TR' tape-and-reel option when ordering. Confirm that the 8-SOIC footprint matches the target PCB layout dimensions. Ensure the application environment remains within the specified -40°C to +125°C operational temperature range to maintain reliability. Cross-reference the datasheet for any recent updates regarding pinout or electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a single-channel, non-inverting low-side driver with high current capability is required. It is suitable for applications needing faster switching speeds compared to standard drivers. Consider the 12A peak current rating against the total gate charge of the target MOSFET. Evaluate the thermal requirements of the SOIC-8 package based on the duty cycle and ambient conditions.

Part Context

The MIC4452VM belongs to the MIC4451/MIC4452 family of CMOS MOSFET drivers. While the MIC4451 offers inverting logic, the MIC4452 provides non-inverting functionality. Both share similar electrical characteristics and are designed to replace discrete component solutions. The 'VM' designation specifically identifies the tube-packaged version of this 8-SOIC device.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers. Check for equivalent peak current ratings and propagation delays to ensure performance parity.
