Overview
The MIC4469BWM is a discontinued quad low-side MOSFET gate driver from Microchip Technology, housed in a 16-SOIC package. It provides independent inverting and non-inverting outputs with peak source/sink currents of 1.2A each. The device operates on a supply voltage range of 4.5V to 18V, supporting logic thresholds of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 14ns and 13ns respectively. It functions within an ambient temperature range of -40°C to 85°C.
Feature Summary
- Provides four independent low-side drivers with dual input logic gates for flexible signal configuration.
- Capable of driving highly capacitive loads such as power MOSFETs with high efficiency and fast switching.
- Built using BCD process technology ensuring latch-up protection and immunity to ground noise spikes.
Applications
- Driving heavily loaded clock lines
- Coaxial cable transmission
- Piezoelectric transducer actuation
Procurement Notes
Verify component obsolescence status before integration. Confirm availability of direct substitutes like the MIC4469YWM if production continuity is required. Ensure design reviews account for the end-of-life notification timeline to mitigate supply chain risks associated with discontinued semiconductor inventory.
Selection Notes
Select this component for applications requiring multiple low-side drivers in a compact form factor. Consider the specific operating temperature range and supply voltage constraints. Evaluate the need for inverting versus non-inverting channels to minimize external logic components. Verify compatibility with the target MOSFET gate charge requirements.
Part Context
Part of the MIC4467/8/9 family of CMOS buffer/drivers designed to replace multiple single-input driver packages. This series improves system reliability by reducing total system cost and component count through integrated quad-channel functionality within a single 16-pin package.
Replacement Considerations
The MIC4469YWM is listed as a direct substitute. Verify pinout and electrical parameter equivalence prior to implementation.
FAQ
What is the maximum peak output current for each channel?
Each channel supports a peak source and sink current of 1.2A.
