Half-bridge driver for N-channel MOSFETs
The Microchip MIC4104YM is a high-speed half-bridge gate driver designed to drive two N-channel MOSFETs in a half-bridge configuration. The independent channel architecture lets you control the high-side and low-side FETs separately, while the bootstrap-ready high-side driver supports a floating supply up to 118V.
The 9V to 16V supply range aligns with standard 12V bias rails found in industrial and automotive systems. Logic input thresholds of 0.8V (VIL) and 2.2V (VIH) are compatible with 3.3V and 5V controllers, so no level-shifting is needed when driving from a typical MCU or PWM controller. The non-inverting input type means a logic high on the input turns the corresponding output on directly.
Surface-mount assembly keeps the profile low for dense boards.
No last-time-buy or obsolescence risk is indicated.
