MC33151D

The MC33151D from On Semiconductor is a dual inverting high-speed gate driver. It is specifically designed for applications requiring low current digital circuitry to drive large capacitive loads with high slew rates. This device features low input current, making it compatible with CMOS and LSTTL logic. It also includes input hysteresis for fast output switching, independent of input transition time.

The MC33151D has two high-current totem pole outputs, ideally suited for driving power MOSFETs. It also incorporates an undervoltage lockout with hysteresis to prevent erratic system operation at low supply voltages. Typical applications include switching power supplies, DC-to-DC converters, capacitor charge pump voltage doublers/inverters, and motor controllers.

This component is available in an 8-SOIC surface mount package. It operates over a wide temperature range of -40°C to 150°C (TJ) and supports supply voltages from 6.5V to 18V. The device provides 1.5A of output current per channel and features independent channels.

Key electrical characteristics include a logic voltage compatibility of 0.8V and 2.6V, with rise and fall times around 15ns for a 1000pF load, though specific values in the database show 31ns rise and 32ns fall.
