MC33151P

Overview

The MC33151P is a dual low-side MOSFET gate driver manufactured by onsemi, designed for robust switching control in power electronics applications. It features two independent drivers capable of sourcing and sinking up to 1.5 A of peak output current. The device operates within a supply voltage range of 6.5 V to 18 V, supporting standard logic levels with defined input thresholds of 0.8 V (VIL) and 2.6 V (VIH). Electrical performance includes a propagation delay of 100 ns, with rise and fall times of 31 ns and 32 ns respectively. The component is housed in an 8-pin PDIP package suitable for through-hole mounting, ensuring reliable operation across an extended temperature range.
