MIC4468BN

Overview

The MIC4468BN is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent non-inverting drivers with peak output currents of 1.2 A for both sourcing and sinking. The device operates within a supply voltage range of 4.5 V to 18 V and supports logic input levels of 0.8 V (VIL) and 2.4 V (VIH). Typical rise and fall times are 15 ns and 15 ns, respectively. It is housed in a 14-pin PDIP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent low-side gate drivers for simultaneous control of multiple power switches.
• Provides high peak output current capability of 1.2 A to ensure rapid switching transitions.
• Features non-inverting logic configuration compatible with standard CMOS and TTL inputs.

Applications

• Motor drive systems requiring multi-phase control
• Power supply circuits utilizing synchronous rectification

Procurement Notes

Verify the specific manufacturer source, as this component may be distributed through third-party entities such as Rochester Electronics. Confirm RoHS compliance status and moisture sensitivity level prior to procurement, as these attributes can vary depending on the production batch and distributor channel. Ensure the package type matches the required PCB footprint.

Selection Notes

Select this component when a quad low-side driver configuration is required for cost-effective multi-channel power management. It is suitable for applications needing moderate switching speeds with 15 ns transition times. Consider the 14-pin DIP package for through-hole assembly requirements. Evaluate thermal performance if driving high-capacitance loads continuously.
