The new ON Semiconductor intelligent power modules in 15 A and 20A versions integrate a power factor correction (PFC) converter, three-phase inverter output stage, pre-drive circuitry and protection in a single, compact package to reduce part count and board space. Microcontroller-compatible low-voltage input and status outputs support further component and space reduction by eliminating the need for photocouplers between a host micro and the IPM.
The devices feature built-in cross conduction prevention, which reduces the possibility of system malfunctions caused by noise, and over-current protection for both the inverter and PFC section. Under-voltage lock-out ensures IGBT gate shutdown in the event of abnormal conditions. The devices are certified to UL1557 and offer an externally accessible embedded thermistor for high-precision monitoring of the temperature of the insulated metal substrate.
