Overview
The MC33151DR2, produced by ON Semiconductor, is a high-speed dual MOSFET driver designed for applications requiring low current digital circuitry to drive large capacitive loads with high slew rates. This device features two independent channels with high current totem pole outputs, making it ideal for driving power MOSFETs. It is compatible with CMOS and LSTTL logic inputs and includes input hysteresis for fast output switching. The MC33151DR2 also includes an undervoltage lockout with hysteresis to prevent erratic system operation at low supply voltages.
