Overview
The MIC4469ZN is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent drivers in a 14-pin DIP package, supporting supply voltages from 4.5V to 18V. The device provides peak output currents of 1.2A for both sourcing and sinking. Typical rise and fall times are 14ns and 13ns respectively. Logic input thresholds are defined at 0.8V (VIL) and 2.4V (VIH). It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides four independent low-side drive channels for N-channel and P-channel MOSFETs
- Supports CMOS logic inputs with specified voltage thresholds for reliable interfacing
- Delivers high peak current capability for rapid switching of power devices
Applications
- Low-side switching applications for power MOSFETs
- Industrial motor control systems requiring multiple channel drives
- Power management circuits utilizing CMOS logic interfaces
Procurement Notes
Verify the specific suffix ZN indicates the commercial/industrial temperature range and PDIP packaging configuration. Confirm RoHS compliance status as some sources indicate non-compliance. Check for obsolescence notices or active replacement part numbers such as MIC4469YN before finalizing procurement plans.
Selection Notes
Select this component when four independent low-side drivers are required in a through-hole DIP package. Ensure the application voltage remains within the 4.5V to 18V range. Verify that the 1.2A peak current meets the load requirements. Consider the operating temperature range of -40°C to +85°C against environmental conditions.
Part Context
The MIC4469ZN belongs to the MIC4467/8/9 series of quad output CMOS buffer/driver ICs. These devices extend earlier single and dual output designs to provide four channels. They are designed for driving power MOSFETs in various industrial and consumer applications requiring robust gate drive performance.
Replacement Considerations
MIC4469YN is listed as a direct substitute. TC4469CPD and TC4469EPD are noted as similar alternatives. Verify pinout compatibility and electrical specifications before substitution.
