Product Description

Product Overview

The NFA32512L72 is an advanced Intelligent Power Module (IPM) designed for high-performance inverter output stages in AC Induction, BLDC, and PMSM motors. It integrates optimized gate drive for built-in IGBTs to minimize EMI and losses, along with multiple on-module protection features including under-voltage lockouts, over-current shutdown, thermal monitoring, and fault reporting. This module simplifies design by requiring only a single supply voltage and translating logic-level gate inputs to high-voltage drive signals. Separate negative IGBT terminals are provided for flexible control algorithm implementation.
