ONSEMI MOSFET Driver Low Side SOT-23-5 3A

The ONSEMI MOSFET Driver Low Side SOT-23-5 3A is a high-speed, low-side gate driver designed for efficient MOSFET switching in power management and motor drive control applications. It delivers high peak current pulses during short switching intervals, ensuring fast and reliable switching of N-channel enhancement-mode MOSFETs.

Featuring dual-logic inputs, this driver can be configured as non-inverting or inverting, with an enable function for added flexibility. Internal resistors automatically turn the driver off when no inputs are present, enhancing safety and preventing unintended operation. The under-voltage lockout (UVLO) circuit holds the output low until the supply voltage is within the operating range, protecting the device during power-up and brown-out conditions.

The advanced MillerDrive™ architecture combines bipolar and MOSFET technologies to provide high peak current during the Miller plateau stage, minimizing switching losses while delivering rail-to-rail voltage swing and reverse current capability. This ensures high efficiency in high-frequency power converter designs, making it an ideal choice for demanding power electronics applications.
