Overview
The MIC4417BM4-TR is a low-side gate driver IC from Microchip Technology's IttyBitty series, housed in an SOT-143 package. It features a single non-inverting channel designed for driving N-channel MOSFETs. The device operates with a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). It delivers peak output currents of 1.2A for both sourcing and sinking. Typical rise and fall times are 14ns and 16ns, respectively. The component functions within a junction temperature range of -40°C to 150°C.
Feature Summary
- Provides high-speed switching capability with typical rise and fall times of 14ns and 16ns.
- Features robust peak output current drive of 1.2A for efficient N-channel MOSFET control.
- Supports wide supply voltage operation from 4.5V to 18V for flexible power system integration.
Applications
- DC-DC converter synchronous rectification
- Motor control bridge drivers
- Power supply load switches
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the 'B' variant matches required thermal or electrical specifications against the official datasheet. Ensure the SOT-143 footprint aligns with PCB layout constraints. Check RoHS compliance status as per the latest manufacturer documentation before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact, low-side driver with moderate current capacity. The SOT-143 package suits space-constrained designs. Compare peak current requirements against the 1.2A limit. Ensure input logic voltages are compatible with the 0.8V/2.4V thresholds. Consider the 150°C junction temperature rating for high-thermal environments.
Part Context
This part belongs to the MIC4416/MIC4417 family of IttyBitty gate drivers. These devices are engineered for small form-factor power management solutions. The MIC4417 specifically offers a non-inverting configuration, contrasting with the inverting MIC4416. Both share similar electrical characteristics and packaging options within the Microchip portfolio.
Replacement Considerations
MIC4416YM4-TR is a related model but provides an inverting output configuration rather than non-inverting. Verify logical signal inversion requirements when substituting. No other direct public substitutes are confirmed in the provided data.
