NFAM2065L4B

Power Driver Modules Overview

The NFAM2065L4B is a fully integrated three-phase inverter intelligent power module manufactured by onsemi. It operates with a collector-emitter maximum voltage of 650 V and supports a continuous current of 20 A. The device integrates six IGBTs, independent high-side gate drivers, low-voltage IC logic, and a temperature sensor (VTS). It utilizes a DIP-39 through-hole package and functions within an operating temperature range from -40 °C to +150 °C. The module includes built-in under-voltage lockout protection and internal bootstrap diodes for high-side gate drive enhancement.

Power Driver Modules Procurement Notes

Verify the specific ordering suffix and RoHS compliance status against the official manufacturer datasheet before procurement. Confirm that the DIP-39 through-hole package matches the target PCB footprint requirements. Ensure the selected component meets the required UL1557 certification standards if applicable to the end equipment safety regulations.

Power Driver Modules Selection Notes

Select this module when a compact, fully integrated solution for three-phase motor control is required. The integrated gate drivers and protection features reduce external component count compared to discrete designs. Consider the separate lower-leg emitter connections if precise individual phase current sensing is necessary for the chosen control algorithm.
